I have gone through 28flights on my frenzy 50, and I have stripped 6 main gears up to date.

The first one I stripped was because my meshing was too tight. There was grey-ish powder around the area. The subsequent ones was either because it was too loose or too tight. I just couldnt find a perfect meshing.

Could it be other factors that caused e main gear to strip? My friend whom flew a Raptor50SE had the same problem too, but after he change his clutch the problem is solved.

The only mod I did was I change the clutch bell to R50 one. Also, after stripping the stock main gear, I have been using R50 ones.

The main gear usually stripped during mid flight and not during normal to idle transition.

Can anyone please help, i am sick of stripping them.

Cheers!

What motor you using. I went to the delirin Raptor 8.7 ratio main on mine and have had no problems. Just be sure to ck your gear mesh you may have to shim the engine with some brass shim.

Do you live in the cold weather states? That may be a factor.

I've been flying my Frenzy for nine months now, and have sripped two mains. The first was the stock one, and the other was a raptor 85 tooth, I'm now running another stock gear with no signs of wear. The Raptor gear didn't last long at all! The clutch assy. is all stock, and I'm using an O.S. 50 Hyper with an Align gov. The heli. has never been crashed, and I would have to guess I have close to a hundred flights. By the way, my gears stripped just as you described!

Seem to me like I have to try my luck with the stock gear again. Thanks for your inputs. Anyone else had this problem?

Cheers

Whew! I am just putting my Frenzy together and am glad to read that the main gear is not necessarily a problem. By the way, how do you fly for 9 months and not crash! How I wish I could just say I flew a month without crashing! I am sooo jealous!

Sounds to me like too much slop in the gear mesh. Check it on different points on the main gear, ie: it may have tighter mesh on 1 side of the gear then the other. Also check for clutch/pinion straightness.

Thanks for all your suggestions guys. I think I found out the problem. Apparently i havent been doing my meshing properly. Whenever I adjusted the meshing, I simply use my fingers to force the pinion and maingear together and the effect doesnt seem to be much. So I stick my starter in and try to move the pinion, I could actually move the pinion a lot closer to the main gear. I think all along I have been flying with too much backlash. This is my first adjustable clutch block heli, so still a lot to learn in this aspect. I will bring the bird out to fly and see how it goes.

Cheers.
