Mine too, I usually look for 7200 on the tach.

Exactly the same as any i've owned

Re post #20, "a bunch more power"...Define "bunch"..
Piped G62, 22A prop, 8400 rpm.....What's a piped DA50 do ? Anybody have one ? Just curious.....

[Jamieman]

Wow.
I only get about 6500-6600 out of my early ZDZ60 on Pitts and 22 x 10 Hawk.
Ultra reliable, but not in that class.

The G62 is a good running and reliable engine, but its not in the same class as a DA50/3W50/ZDZ50 in power. You wont see a G62 swinging 22 and 23" props as those listed 50s will. Perhaps a Zinger 22x8.

This is my RC Ignitions G-62 on CF pipe and 16 1/2 pound EF Yak.

It makes just shy of 7.5 hp but that is an estimate off of the Pei Reivers calculator. We do know that the Vess 22A does hit 8400 rpm and the Vess 23A 7800.

YouTube - EF Yak on steroids.

You just gotta let em breath.

How about a MT62, A G62 Clone { for lack of a better word.
Comes with electronic ignition, stand offs and muffler.
4.5 lbs all up with muffler ignition and stand offs
All parts from prop adapter back match G62
Same power and performance for around $410.00

And then there were 4, a little known history of the MT62i, or MTi 101
Tomy Shen is the Chinese source of the MT62i...He has been E Mailing people to sell his engine...
First sold by Adam at BCMA, don't know if he still does...
I bought a few to test....Rich Border has some...Milton Thompson has some...
The two I had were made with the ignition magnet positioned wrong in the hub, timed somewhere around 50+ degrees BTDC...I told Tomy, he changed the magnets...I think some will have two magnets, the second will have the opposite pole facing the sensor so as not to fire twice...Subsequent versions will have only 1 magnet...
There have been reports of the carb insulator block cracking or leaking, he copied the Horizon plastic carb block...
My version has the G10 epoxy board block with an external pulse line, thinner and NO cracking...
Tomy's prop hub is a copy of the old A&M 6 bolt hub...Hollow inside, held on with a nut, with a single bolt adapter on the end held on with 6 flathead allen bolts...
My version is solid 2024 aluminum...The buyer can specify length...
My version has an extra 6202 sealed ball bearing replacing the front crank seal, 2 front bearings are better than 1....
My version has the crank cut off at the rear bearing with a plug replacing the rear seal...
I THINK we all pay the same basic price for the engine...
OK Adam, Rich, and Milton...Anybody wanna play price games ? I will MATCH or sell my better version for LESS than any of you guys....Lets GIT'R DUN
I will guartantee the ignition FOR THE LIFE OF THE ENGINE, no matter who bought it or how many owners it has....
I have been converting and repairing Zenoah engines since 1987..Where were you guys ?????

Hey Milton, the converted Poulan 46 I sent you some years ago is now the Brillelli 46GT...I guess we both underestimated that one....
An question about when it was done, look on rcfaq.com for the picture of my carb insulator....

[rcign]

Repoly to post #30
The first DL 50 I tested a while back turned the 23-8 at 6700 with stock muffler at my 6800 foot altitude....
It was one of the very first, still had the extruded mount....I made a mount for bench testing, didn't trust the original....

Had to be over 5 years ago, I converted about 6 after that, Sold 5 and still have one. I think the 5 I sold are still flying.

Was not trying to step on any toes with my post about the MT 62. Just letting people know they are out there.
You are right about the timing. The first ones I got were off but I changed the sensers to correct them.

One thing anybody who sells China made engines have to do is test run them before they sell them.

There are some good ones but are not consistent in there manufacturing.

[rcign]

Besides being a little weak in the power department, most of the early Chinese engine problems are/were from sellers jumping on the cheap engine bandwagon...Some QC at the manufacturing level and more at the dealer level would have gone a long way..They WILL get it together someday..

In response to "Chris's" post to me:

Ok... so a MODIFIED G62 is stronger than most of the 50s in the class, I can buy that. But a stock G62 out of the box, absolutely not. Like I said, they are great motors, but are no power houses from the factory unless I got a bum one from the factory. I'm not sure where you are getting your RPM numbers from, but my post comes from my experience. Replaced a newer G62 on muffler on a Hostettler Decathalon with a DA50 on a muffler. DA50 out pulled it by far, and that was WITH added nose weight to make it balance. Those were both with no mods, no changes, out of the box stock. Porting, timing, over all design dictate the over all efficiency of an engine. RCIGN has done some great things with G62 platforms, definetly agree on that one, but its all with modification of some sort. If you would like to pull both motors out of the box, pop the same prop on them, same fuel, NO mods, and videotape the RPM pulls you get out of both motors, you might then sway me that a G62 has more power out of the box than a DA50/ZDZ50/3W50. I know sure as **** my G62 wouldnt spin a 23x8 Mejzlik prop like my DA50 or my ZDZ50 would. I wish I still had the motors so I can so tests and really take a look at them, but I dont. Smallest case I have now is 100cc. My one question would be, If the numbers that a G62 can put up are better than any of the new style 50s out there, why would anyone run a 50 when you can get a G62 at alot less cost... But then I dont see too many people opting for the G62 over a newer style 50. Like I said, great engine, and it has tons and tons of applications out of the box, but I just didnt see the comparison between the one I had and my 50s, of which I have had 3 that were all pretty much the same.
