That was with everything, muffler, standoffs, IE, spark plug, gaskets, screws. I did it with my scale that is accurate to 1g, but now that you ask I'm a little nervous about the number. When I weighed it on the dinning room table I put a towel down to not scratch the table, I don't know if that would change the reading or not. My engine is mounted now, so I'll ask Larry to actually weigh one, I think he did, but he's had so many new test engines I'm not sure.

Rich gave you the right weight on the MT50 engine at 3lbs 9.5 oz. The 50 on my website is another 50cc engine. Have been to busy to update the web page. Sorry about the confusion.

Yesterday on another site I made an offer for the new MT57cc that will be out at the end of the month.
FOR THE FIRST MONTH AFTER THE RELEASE OF THE MT57CC ENGINE THEY WILL BE SOLD ON A MONEY BACK IF NOT SATISIFIED
BASIS. THATS RIGHT, MONEY BACK NO QUESTIONS ASKED IF YOU ARE NOT SATISFIED. To the best of my knowledge that is the first time anyone ever made this offer. TOMY R/C and LS PRO ENGINES have that much confidence in the new engine to make that offer. Now I will make the same offer for the MT50cc engine. MONEY BACK IF NOT SATISFIED for the rest of this month. So guys
if you are on the fence to buy or not to buy this is your chance, what do you have to loose.

RE: MT50cc ?
Rich,
Any more news on break in of your new MT50? I am waiting on a shipping quote from Larry at the moment and would like to hear how you are making out with the new machine.

I don't do RC on the weekends, but I did play with updating LS Pro's website today, so some new stuff there. I don't work for Larry, or he would have fired me, the website had gotten really out of date, now it has his specials on he's new motors.
I normally run a canister if I can, but this little plane doesn't have the room. I put a MT62 muffler on it tonight because the MT50's is larger and I'm trying to squeeze this into a small cowl, I'm happy to report the MT62 muffler bolted right up no problem. Doesn't look like I'll be going out soon 19* and 22mph forecasted for tomorrow.

RE: MT50cc ?
Thanks, Rich. I look forward to more updates.
We just got 2+" of snow and it's been -24C for the last couple of days, with -37C wind chill. Another 1.5"-2" forecast for tonight. At least it's supposed to be around freezing tomorrow. In other words, you get no sympathy from me!

RE: MT50cc ?
This is interesting as far as how much hype these MT 50 engines are getting. People are getting excited because it is something “New” in the market hoping that it will be something different. Well, I did some research on the engine and the manufacturer (Tomy RC) and I found that all he has done is machine the casing. In fact the rest of the parts come out of the cheap Chinese moped type bikes. There is no innovation here other than assemble part together. As far as some of the claims that I have been reading about aerospace quality materials… Yeah! The best the moped Chinese industry can offer! The claims on some of the advertisements that are out there say that this engine was specifically designed for RC in mind. Perhaps assembled, but not designed.
At this point I am already skeptic since some of those BOLD statements have been disproved. Take a look at the following links and you be the judge.
This is the head of the engine. You can see it at this link http://www.scooterparts4less.com/web...ylinderKit.htm
Look at this engine! Does this look familiar?
http://www.pocketbikeparts.com/Photo...ode=CGEN302226
The cool blue looking head is nothing more than a choice from one of the yellow, red, or silver heads offered in a mini bikes upgrade kit. You can find this at this link.
http://www.pocketbikeparts.com/product_p/cgcy302100.htm
As you know the MT 62 is nothing more than a G62 on an electronic ignition conversion (nothing special)
The MT-42 is I have been told that it has tons of vibrations and the back plate that mounts the engine on an airframe eventually shears and shatters in multiple pieces. You can imagine what can happen to your model if you fly one of your planes with this thing….
As far as the service I understand that some gentleman that has experience in fixing engines will be doing the repairs (Cunningham), but from what I understand he has reached a retiree age. He might be working for a couple more years, but I wonder for how long in the long term? How long do you think the long term service will be?
The MT 50 seems to have some serious twisting moment potential concerns due to the way the head bolts on the casing. Those long bolts and how they attach to the rest of the setup might introduce twisting and shearing moments especially after the head will reach operating temperature. Especially when the head will expand due to heat, the bolts will apply asymmetric force ultimately distorting the head. I wonder about the long term reliability on this engine.
As far as the MT-57 so far as for what I have seen and read it seems that it has some good potential, but it is too soon to make a judgment call since it has not been in the market yet.

You make a large number of very inflammatory comments and remarks in your post.
1) Your first link shows a top end that looks nothing like the MT50
2) The second and third links do show parts that look identical to the MT50, SO WHAT? Small engines are anything but custom made and many different engines use common components.
3) To say that Ralph Cunningham has "some" experience with engines is a bit of an understatement. Ralph is well past the point of retirement, he works for enjoyment, not the money.
4) I am curious how you think the top end bolting arrangement will cause twisting? Do you understand what asymmetric means? Four bolts arranged radially around the cylinder is very symmetrical. The separate head/cylinder arrangement may introduce problems and it may not. Many air cooled 2 strokes have been assembled the same way in motorcycles with no issues.
I also note that you joined RCU TODAY and immediately started these posts. If that is not suspicious, I don't know what is. Perhaps you should take your time before throwing up these very biased, venom laced posts or find somewhere else to complain about things.
Note, I have no connection to LS Pro or Tomy. But I do feel that an unwarranted attack like this can't go without a response.

RE: MT50cc ?
this guy has a agenda, he is posting this same post on other boards against the MT50, why would anyone go around on the different boards posting negative comments on a engine if he did not have a reason?

RE: MT50cc ?
Over on the other site , i saw his post and i was the first to confront him about it. Usually when somebody slams a company for his very first post........99% of the time it's because there "IS" an agenda behind it. He said his name was "WIK" , and maybe that's true , but man , talk about an agressive first post!! He went into lengths to slam the MT motor line , and mentioned that they used "other" brand" type scooter motor's and so forth to build the MT engines......SO WHAT! Berelli , FPS , Taurus and many , many more are all some type of an original sach's based type conversion.....correct? Who cares about that.....as long as the engine runs fine.
Wik.....now that i've seen your post ( EXACT same post ) on a couple different sites.....you my freind have an agenda. You must! And since you are so new to all these boards.....why would you all of a sudden join ALL THE BOARDS in one single evening and post the same post?? HAHA , i think it's funny as #*&#!! AND , since you are so knowledgable about all these motor's.......your just now joining a message borad??......hmmm?? I think myself and many others can see right through you like a piece of saran wrap my friend .

RE: MT50cc ?
You are free to comment on my post all you want. We live in country that allows us to express our opinion freely! You keep on saying that I must have an agenda. Well I will post some pictures and you will understand why! The MT 42 is a dangerous engine as it has too many vibrations. I will post a picture of a shattered back plate. This happened up in the air. I bought and MT 42 and a MT 50 from Australia. I guess not directly from China. The 42 raddled my plane to pieces, and on another different plane the 50 after a minute hover on the plane started to sag and loose power. This was on a cowless extra 300 15 lbs. After I landed the plane I realized that two head bolts had come undone.
You are saying that I have an agenda. I guess I am disappointed because I lost one plane (from the 42) and got frustrated form the other (50) and wasted time and money on the engines. Initially I was excited as both engines looked very promising. Actually the 42 has a lot of power, but the truth is that one cannot do much with uncontrolled power (vibrations).
Tomy RC send me a private email confirming that the engines are made from scooter parts. He also told me that the cylinder is not the same one as I pointed out on the link other than the blue head (if you want I can post his comments on this thread) . Well the one that I have here is identical to the link that I posted. Perhaps I got stuck with one of the older releases of the MT 50. I can only speak about what I have experienced.
I have no regrets of what I have posted about the engines since that is what I have experienced. Since you are so militant and observant I am sure that you have read my comments of the MT 57. I said that it seems to be a fine engine, however, nobody knows as we have not tested it yet.
My only REGREAT in respects to my comments is for Mr. Cunningham as he seems to be a fine gentleman that has a lot of passion and dedication for what he does. However, the engines are what they are.
I understand what you are saying that all engines are some type of crossbreed form different parts and I have no problem with that.
I only have a problem with blown out of proportions and untrue statements. In all the forums that I posted the MT 50 engine is advertised as a “specifically designed” with “aerospace engineering materials”, lightest in its class etc. That is bluntly NOT true. My personal experience has shown me other wise and the links that I posted earlier prove that. THAT is the ONLY issue that I have here. I am an engineer by trade (cannot post for who I work for), and inconsistencies like this make me mad as it is not fair to the rest of us.
Scott at Brillelli and Adam at BCMA do not claim that their engines are made out of “intergalactic metals” nor that their engines have been exclusively designed for RC use. They both offer a fine product without undermining their competitor’s products. That I respect! I guess I will post a picture of the shattered back plate and you tell me what you think… Is that fair?

RE: MT50cc ?
Wik....before we debate any further , i would go visit the "other site" in the gas engine forum. You have a way better chance of speaking your opinion there without getting it deleted. I love it on here at RCU , but some time the moderators delete things for no good reason. I replied over on the other site as well.
also..in case you don't go back over to the other site..........we're the engines in question you we're using the "older" versions? Like the ones that we're released about 4-5 months ago??

Yes the one released over 5 months ago. So As long as i agree with everyone else I can have an exchange in this forum, but if I disagree I will be kicked out? So much for the cordial freedom of speech. Now you are actually making me mad.

Well I was interested in this engine line when I found out Ralph Cunningham was involved. After reading this thread I’m not any longer. Not because I think the engines are bad. I haven’t any concrete evidence to support that. I’ve got a problem with all the childish attitudes displayed here. Most of all I have a problem with someone that’s suppose to be a professional. A person who’s trying to market a product but when another person has a different opinion they feel the need to make it personal or get belligerent. It makes me think to myself is this the treatment I should expect if I have a problem. I’m not sure I care to take that risk. Don’t get me wrong there is a right and a wrong way to defend your product. Personally I would have chose a different way.
Just one last thing for the record I see many posters in this thread with agendas. One that claims to have owned several of these motors without success, One that wants to sell you these engines and several that are running to the importers defense even though some don’t own the product (it appears) or they might be affiliated with the importer in some fashion. Buying an engine or learning about a new product shouldn’t involve this much drama. What a waste. I wish everyone the best of luck.
P.S. I do hope the mods leave this thread in tack much can be learned by buyers who have a complete picture

That is how I feel too. It sounds like a whole bunch of kids defending their pride and not taking ownership. Any way that is another story.
For some of you that think that I have an agenda, here, I am posting my agenda in the included pic. Enjoy!

RE: MT50cc ?
Hmm, interesting development and talk on this thread.
I have 4 of the MT engines. Two MT -42 and two MT-50. I have tested both engines and to be honest with you they are ok. However, I have the old style MT-50 so I cannot speak for the new upgraded one. I have not tested either one on a plane yet. All my testing has been done on an instrumented engine stand.
I sent an email to Tomy RC to get an upgrade kit for the MT-50NG so that I can compare the old and the new. On a testing stand, I as well experienced the MT-42 back plate braking after 5 hours of nonstop operation. I understand that if mounted on a wooden airframe part of the vibrations would be absorbed thorough the wooden airframe. However, I have not tested it on a plane yet, so I have no opinion on that.
I have been tinkering with balancing the internals of the engine to make it smoother. I am not ready to make any claims yet. I am dynamically and statically balancing the engine. I know that I have worked on a SPE 40 engine in the past and after some standard modifications to the engine I managed to get out of the SPE-40 about 7550 rpm on a Mej. 20X8. Anyways, for whatever it is worth Tomy (Shen Ping ) is a hard working and dedicated man that is trying to develop a good product. Well as far as the slander that I noticed in the last few posts that seems to be childish (form both sides).

You are free to comment on my post all you want. We live in country that allows us to express our opinion freely! You keep on saying that I must have an agenda. Well I will post some pictures and you will understand why! The MT 42 is a dangerous engine as it has too many vibrations. I will post a picture of a shattered back plate. This happened up in the air. I bought and MT 42 and a MT 50 from Australia. I guess not directly from China. The 42 raddled my plane to pieces, and on another different plane the 50 after a minute hover on the plane started to sag and loose power.

If you had posted this info instead of just dumping all over the MT50 we would have responded much differently. I am interested in a new 50cc engine in the next month or so and user experiences, both good AND bad, are important info in my purchasing decisions. I would like to hear more details of your experiences and results with the MT50 engine. How much power, how well it idled and transitioned, etc. Maybe some more details of your installation and how it all worked.
You don't need to run or hide here if you post intelligent, informative posts or honest questions. Your first post can't really qualify on any count for those criteria, though. Stick around and share your experiences, but be sure to include ALL the details and information. I understand why Larry got hot about your post, it was extremely negative with no apparent reason behind it. His response was his choice, leave it at that.
TxDiveBomber, I wasn't running to the defense of LS Pro so much as not being willing to let anyone post invective like that. Regardless of who it is about, that does not belong in a public forum. As I said above, if Wik had posted more details instead of letting emotion run away, it would have been very worthwhile and acceptable. If users have poor results with these engines, I want to know about it before I commit $$$ to one. But to just let it go like he did is going to generate a lot of negative replies no matter who or what you are trashing. You generally get what you give.

I couldn't agree more mark. It wasn't the bash on the MT line of engines , but just the bash itself. It didn't matter which company it was , but the fact that it seemed to be extremely negitive. I can completely understand his frustrations , but we all need to see and hear what is going wrong. I took it the wrong way at first , because it was his very first post , but now that he's replying to the threads , we should help him get to the bottom of his motor problems and get the thing fixed. I think Tomy over at TOMYRC is supposed to a be a really stand up guy and works hard to make his motor's run good. And again , with Ralph Cunningham standing behind these motor's.......you couldn't ask for a better repair man.
I think there is definetly going to be kinks in "new" motors that are being released , regardless of who they are from , but i also believe that TOMYRC is a guy who will do what it takes to get the kinks worked out.

RE: MT50cc ?
IN OUR DEFENSE:
I am going to make this my last statement on this utter ridicules back and forth pissing match.
We made no claims that we are using any aerospace materials in our manufacturing of the engine.
How many bikes have you seen with our engines in whole on them?
Milton has tested and sold the MT42 with no problems with the engines
Milton has tested and sold the MT 62 with no problems with the engine
Milton has run tests on the MT50 and it did not meet with his expectations and gave up early and went on to another make 50cc engine.
We got the MT50 engine and although it is of fine quality, in material and workmanship it needed to be fine tuned to get it to perform.
We started with 6200RPM out of the box and with changes in tuning we have it at a respectful 6850RPM with a Vess 22A prop, getting stronger with being broken in. There IS NO ISSUES WITH THE LONG BOLTS!!!!! After having run 3 gal. of gas. Running up to temp stopping to cool and repeat cycles, of hot to cool many times. After sufficient time I can see it turning a reliable 7000 RPM. with a 22” prop.
There was an issue with the MOUNTING PLATES on the MT42 and they are being replaced with a new material. Broken plates can be from many factors, some being the fault of the person mounting the engine.
Milton has some new plates coming his way to replace any bad ones.
There is a difference between having a problem with a product and having a problem and DOING SOMETHING TO CORRECT IT.
Every engine out there has had some type of issues with them in the infant stages, the difference is taking care of the issues and going on.
Until we are sure that any issues that come up with our line of engines we will Check EVERY ENGINE before it goes out the door. This will minimize any problems and also remember we are selling on a MONEY BACK if not satisfied basis.
Ralph Cunningham has had our engine for over a week and is testing and making recommendations, when he is complete with his findings he will issue a report. So far all his feedback has been favorable.
Remember we are a phone call away for support when you buy from us.
Questions before you buy will be handled by e mails. Feel free to ask.

RE: MT50cc ?
The 50 was very hard to start initially. I got an hour workout before I got it to pop. I did all the typical stuff. Wet the diaphragm on in the carb, turn the prop until the fuel in the fuel line reached the carburetor and then a sequence of choke on, flip-flip-flip until it pops, then choke off, 1/8th open throttle and keep on flipping for the thing to start. I got a good work out and then it finally started. The engine idled very smoothly at about 1600 rpm with an NX 20 X10 prop (since I was breaking it in). Oil mixture ash-less 50:1. Top rpm about 7000 rpm with a pull of about 21 pounds. The next starts took about 10 to 15 flips to get the engine started.
Mounted the 50 on a Wildhare Edge 540. All bolts on the head were applied blue thread lock. I used the engine for about 3 months got a 100 RPM increase then one day while hovering at ¾ throttle I noticed a change in pitch in RPM while keeping my throttle constant on my transmitter. It started to lag. Tipped the plane forward corrected it and then shut off the engine. I laded it and a post engine check showed that two of the long head bolts had become undone…
The 42 was on a Great Planes Su-31 (160 size). The engine was mounted directly on the firewall as instructed by the manual of plane not much to it. I also applied blue thread lock on the stand offs on the engine side and on the firewall blind nut side. I flew the plane for about 20 flights I thought it was ok even though I noticed that my ailerons and control surfaces rattled too much at about 3000 RPM. I thought that well it is a gasser and did not pay too much attention to it. One day I was cruising around at about 3000 RPM the next thing I hear is a loud “GUNK” noise and the nose of the plane folded. The prop while still spinning hit the left wing cutting it in half. I was so confused. After taking a look at the plane parts I saw the motor mount in the condition that you see in the picture.
I kept low all this time as I understood that this was a cheap new engine form China that I took a risk on so I accepted that this was partially my fault for making the decision to buy it. I went around my business. What set me off was when I saw the hype and blunt exaggerated statements about these engines. I cannot stand when people claim to false statements, especially when I have firsthand experience otherwise. Yes I was pissed off, in fact I still am. This is my reality.

RE: MT50cc ?
Nice change of style and tone Larry.
This is probably a more professional approach and attitude to have.
On another note I believe that this is one of your ads and posts. I did not fabricate any of my claims about exaggerating what you sell.
Based on your post below this is what I get:
Bullet #1. Like I said moped parts. It is ok with me, but do not make this claim
Bullet #2. How about a DA 50, an AREA 51 or a FA 51?
Bullet #4. Not true again same thing like bullet #1
You get the idea. Do not try to overpromise and perhaps under deliver. I cannot stand that!
