I flew a 33% eXTRA with a G62 and it flew very scale,,, taking off don't keep your nose more than 10 degree abobe the horizon,, it flew like a big trainer

Lighter flies better, nicer and it's a lot more fun,,,, it's also a lot of fun when you can start an engine on the 4th flip of the day or on every 1st flip after tha first flight!!!! like with my DA

AeroDave

Db,
you asked me what the reduced weight if E ignition would yeild. Sorry it took awhile to get back. While the 28% Extra cleanly pulls out of hover, the transition into harrier can at times be a bit critical. Also, when pulling into a hover, unless you go for a full blown wall or a gentle 1/4 loop, it sometimes drops a wing as if its about to snap. Even though I've harriered entire tank fulls with this plane and the stock G62, I feel a lighter wing loading would just make it respond more favorably when pushing past the stall into high alpha flight. Also, it would take less work to get the CG where I like it.

Aero thank you. But budge wise I think im going to go with the stock G62 and upgrade it at a later time. I really like what I have ready about the G62, and feel that it is the motor for me. Again thank you for your help

AeroDave

I know what you mean. I'd like to have a DA 50, but G62 will never be for sale! I've had it in a bunch of airplanes and never had a dead stick landing.

I'll probably never buy a DA. They look nice--but they just won't swing a prop like the G-62 can.

The guys running the DA can talk all they want--but I've never been able to get one of those guys to put there plane next to mine and have a prop swingin' contest. Thats 'cause they know that they'll get their butt stomped.

I did hassle a guy enough one time to get him to put his BME50 next to my G-62. He was talking trash, so I told him to put his money where his big fat mouth was.

The G-62 spanked his BME50 up one side and down the other. It was pathetic. I took his money and smiled at him real big.

Prop for prop--the 62 will outswing the BME50 by close to 1000RPM. Doesn't matter what prop it is. We tried several.

I imagine the same thing would happen if you put a 62 next to a DA50. Never happen though. The DA guys know they'd get spanked.

Anyone wants to call my bluff? Come on out to Colorado with your DA50 and we'll take pictures and videos. Bring your trash bag--your gonna need it after the 62 chews up your DA50 and spits it out in tiny chunks. I'll run one stock and one modified with electronic ignition and aluminum muffler. Spank your butt. Thats an open challenge to ANYONE with ANY 50cc engine that wants to go all out in a prop swingin' contest against a G-62. I'll even supply all the props. We'll go from 20-8 all the way up to 24-10 and everything in between. Probably cost me $500 for all those props--but it would be worth it to shut up all the 50cc guys who think their engines can compete with a 62.

Any takers?

I dont want to cut and paste a whole other post but we had a discusion in the gas engine forum about putting the old 62 on a diet. Mine is not sub 3lbs like a DA50 but its close. Oh yeah its a 62 and not a 50. All the info is in the other forum. (gas engines)

My 62 has had minor port work done buy a 2-stroke motorcross builder. Its been so long since I put I tach on it I'd be affraid to say exact numbers but I do remember a 200rpm increase spinning a 22x10 menz I now swing a 23x10. My 62 is 8yrs old and I will put it up against any 50 out there. .

I am really close to odering a 13-1 compression head for it from Daves motors. My only fear is making it idle rougher, every time Ive done this in the past engines always hit a little harder and shook a little more at idle. However I would'nt be suprised if that and a tuned pipe added 500+ RPM.

It deadsticks all the time though, I cant seem to get it to run without fuel. ONCE I have solved this mystery I shall post my results. Im sure others have encountered this problem with thier 62's.

Good one Rcpilot!

I'm just thinking about the math a little and it seems to me that a G-62 is about 24% larger that a DA-50. How does you G-62 do in a prop swinging contest against a 75 or 80 cc engine.

Rcpilot

My Feedback: (78)

Thats exactly the point.

A 75--80 engine will whoop the pants off a G-62. Myself and noone else that I've ever heard of has EVER said that a G-62 can compete with a bigger engine. That'd be---well, stupid--to think that the 62 could compete with an engine that has 13--18cc more displacement.

It's NOT the 62 guys talking trash and claiming their engines will run with an 80. Noone has ever said that.

But the 50cc guys like to talk smack and they are ALWAYS running their mouths about how this 50 or that 50 will outswing a 62. Can't happen. 12cc is 12cc. You can't compete with that engine displacement. More cubes wins everytime.

Don't try and turn this into an argument where the 62 is compared to an 80. I don't think I've EVER read a post on this forum where someone was stupid enough to compare a 62 to a 75 or 80.

It's about calling out the guys who talk tough about their 50 engines. It's an open challenge to ANYONE with ANY 50 size engine that thinks he can run with a 62.

I've been on my soapbox before about this very subject. I think it's completely stupid and total BS for a 50cc guy to even compare the 50 engines to a G-62. They are in 2 totally different classes. One is a 50 and the other is a 60. Plain and simple. They shouldn't even be compared to each other. But, there is all this myth, hype and mantra--mostly from DA guys--that their engines will run with a 62.

They're in different classes. They shouldn't be compared with each other. But it continues to happen, daily.

I'm just sick and tired of all the trash talking about the 62. People who have never even had one will repeat, time and again, how it's low on power and it's too heavy.

I am willing to buy a BOATLOAD of props just to put this one to bed once and for all. I'll buy 20-8, 20-10, 22-6, 22-8, 22-10, 22-12, 23-8, 23-10, 23-12, 24-6, 24-8, and 24-10 props from various, well known, manufacturers. I'll buy 2 of each.

No excuses. Bring whatever fuel you want to run and I'll run my Husqvarna chainsaw oil at 40:1--just like I always do. Bring your tach. Bring your camera. And bring your drill jig for your engine.

ANYONE wants to come to Colorado--or ANYONE IN Colorado wants to answer my challenge--bring it on. Let's settle it once and for all.

No need to buy two of each. Let him drill the props for his DA50, and you can use the same prop on your G62 with the single 10 mm prop bolt.......

If you are taking the time to install a billet head, the 13:1 (uncorrected compression ratio) dome is sufficiently close to the stock uncorrected compression ratio that the performance gains will be relatively slight. You'll have much better cooling, though.

For a noticeable performance gain, I'd recommend selecting a 15:1 dome, as long as you are comfortable running 100+ octane fuel (easy to find at many gas stations, hobby stores, and motorcycle shops).

I would like to measure a G62. I just couldn't imagine its more than 9.5:1 Thats typically around the std for general purpose 2 strokers.

I buy 110 and 116 for my drag cars but just dont want to give someone an excuse when thy see that old g62 go skyward like a bottle rocket.

My 62 is already ported so buying that new cylinder would mean having that redone as well. That and a pipe would be awsome. The next limitation is the carb. I wish i new of the next biger bore size that would fit the bolt pattern. Wiseco could custom cut a piston also for compression. If you do this you'd might as well over bore it. I KNOW on my motor that would put me around 3lbs maybe a tiny bit over. Probably around 68-70cc. I cant remember how much material is ther to work with.

ryan@ddm

The G62 has a CORRECTED compression ratio of 8.2:1. The '13:1' dome you see is an UNCORRECTED compression ratio, and with the stock port timing on the G62 it's about a 8.8:1 corrected compression ratio when you use this dome.

So the 13:1 dome will give you slightly more compression, but not much.

Hi, I live in Christchurch New Zealand and have just started to put together my 28% 300lx with a G62, I am dead keen to get myself a ignition conversion and wondered if you have an address / e mail for a contact to buy one of these, also can I install the unit myself, i have a pretty good hand with most engine type matters or is it a case of sending the engine away for the set up, which in my case would be unsuitable due to freight costs. As for a muffler I am building a nice light weight alloy one and wonder if there is a perfect volume to the muffler, the prelim model I have made is a tad smaller in internal volume to the heavy bulky stock item and a lot more smooth flow orientated with similar sized outlets.
This thread has made some interesting reading, I was going to get a DA50 but really at the price of the G62 I feel I have not gone far wrong.
also wondering what brand of 2 stroke oil you G62 owners are using? I have had many 2 stroke motorcycles and over a period of time a group of my friends and I all ended up using nitro boosted ROCK OIL, never had a problem in years, smells great and a good price.
Cheers to you all.

anybody else do the ignition coversion for cheaper? is it possible to do it yourself?

I installed the c-h ignition with no problem. You do need to know how to set the timing and find top dead center.

You guys talk about your power with the G62's and having more power than the 50ccers,but you forget to tell everyone that the engine is 12cc's bigger.I have a Evolution 45,DA50R and I am fixing to order a G62 and have had a G62 in the past,they are all good engines,but when you tell it tell it like it is and don't leave anything out,it is a bigger engine so therefore it should have more power.
