RE: DA50 or G62
ORIGINAL: Rcpilet
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.

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.

RE: DA50 or G62
I uh, might be willing to put my little G62 up against an 75 or an 80..
She's just over 10yrs old and really starting to loosten up. I can swing a menz 22x10 at a peak of nearly 8700rpm and run it 8200 or so. My new ignition adds a little on to that. A good can would add a little more.
Yep the old girl is starting to loosen up after all these years. I never could afford to buy one of those hi dollar euro imports so I just had to stick with the old reliable G62 (which everyone tells me is a boat anchor with no power.)
go to the gas engines forum and check it out.

There is no way it is turning the 22X10 at 8700rpms, and a ZDZ80 or a 3W-75 would eat the G62,,, is there anyone that would disagree,,,,

RE: DA50 or G62
Well, whats a good tach?
Ill be home on the 30th and will go out and buy another tach. Ive used this one for years and its always worked though. I knew I should have used a couple of different tachs. The next reading will be off though. Its too much of a pita to go back to single spark.
That reading was done leaned out to peak and thats the loudest Ive ever heard that prop. Richened back it runs around 8K pretty well. I should have a 24x10 at home by the time I get there. ( I hope )
I have a 3w75 would you like me to run it and take pretty picture.
Ill try to get the rpms and pics posted with the twinspark and pipe within the next 30 days. Im an airline pilot and havent been home in while so If I dont get some time with the little woman I might have divorce papers delivered sooner than later. She was really excited to be my assistant in the last running. When I called home tonight she reminded me what a great time she had [&o]

RE: DA50 or G62
I would definately buy a DA50 just for the service & support.
I was having trouble starting mine (had bought used here at RCU) & in the process of removing the spark plug (to clear overflooding) stripped out the plug threads from the head. expecting a huge bill, conactted DA & sent the engine in for service.
Got it back within a week with a NEW Cylinder, Piston, Piston Ring, Bearings, Reed Valve etc all covered under warrantty !!!!
Last time I sent it in for service , they replaced the crankshaft, conrod & bearings all under warantty.
DA's service is Awesome...

RE: DA50 or G62
I had bought mine used here at RCU, I had it for around 1-1.5 years with appx 70-80 flights. Prev owner had said that he had 30-40 flights,
Tthe engine did not have seem to have good compression (we were able to swing it with a 12V starter) & would overflood all the time w/o popping. I was having a hard time to get it started & thats the reason I sent it in for service.
Just got it back today & have not started it since.

It is supposed to start up to a DA-50. Still though, hope it fixed your problem. I found on mine I was flipping too much when choked. Changed how I was doing everything. 4 flips with choke on/ignition off then switch ignition on, next flip it pops. Choke off and within the next 2-3 flips it starts.Jarrod

RE: DA50 or G62
Hey Jarrod, Actually I was able to swing the engine with my 12V Hobbico starter at home also ;-)
Spoke with DA & it seems that the engine had low compression which was making hand swinging not fast enough to start it. Have'nt started it after getting it badk & have to break in in etc. Hopefully whatever the issue was have been fixed.
Anyway, the point I was making was that I am VERY impressed with DA service & support, & thats the primary reason that I would buy another engine from them ;-)

RE: DA50 or G62
fyi: Ran the engine today & it starts w/o a problem in 3-4 flips .
Guess whatever DA serviced, fixed the probelms I was having. Now all I have to do is break in the engine with a few flights/gallons...

RE: DA50 or G62
guys im not slashing g62 but do any of you ever consider wing loading. i mean yes, a g62 can out swing a 50. i will not deny that but the fact is...its a brick. check out 3-d flyer or ask any aerobatic pilot, a lighter plane flys better. 1-2 lbs can make a big difference. if you want to learn or advance in 3-d you need a light capable plane and a plane with 2 lbs extra on the nose will not fly nicely. i have also had a bad experience flying a high wing loading plane, i had to land it at 25 mph. if its designed for a 50 save your money and get a nice light 50. is the extra weight worth the extra 500 rpms?

RE: DA50 or G62
Ya know I want even get into the debate but here is what you do to self educate yourself
Get a DA 50 all up weight
engine
spark plug and ignition
offsets or mount
what ever exhaust your using and put it on the scales.
THEN go do the same with a G62 with electronic igniton with tail shaft cut etc.
Check out the number and then think that the 62 is a 62 not a 50. Whew maybe she is not a brick after all. I like the DA50 its a sound design and jewel to look at. Its a great engine for 15-17lbs after that its done, period. The 62 is for a 16-19lb build. I have a "slightly" modified G62 Im thinking of putting in a 33% to save weight.
With weight make sure you are comparing apples to apples. Some one needs to do a web page un biased with all up wts. [&:] Who woulda thunk it

Bob had the G62 listed in there, but removed it because people complained "it isn't a 50cc engine..."
And, Ralph at RCIgnitions has a version of the G62 weighing just over 4#, including mount, ignition, muffler, SWITCH, and BATTERY. And, it costs nearly 20% less than a bare DA, without exhaust.
