Gp-61

Do not have much time on my xion props. The 24x9 seemed nice. 24x10 bogged the motor it was on down, but it was brand new. If you are after noise reduction the Mejzliks tend to be better than the Falcons. 24x10TH will not disappoint. The only CF props I have been disappointed with are PT gas, but to be fair I have only tried them in oddball sizes.

I'm not having good luck with the piston retainer clip on my two GP61's. Just had my SECOND engine crap itself in flight. Both times I had the exact same part failing in flight... Both times in the same way: fouling the cylinder, piston, and ring.

Waiting to hear back from Kole as I bought it from him. He took care of it last time, as It's under warranty of course, and surely he'll warranty this engine too... but I'm still frustrated with my luck. :(

Jeez Gary, what did these poor engines do to you to deserve your luck.... LOL

Are you running snake oil or something???

VP 50:1 premix.

Not exactly snake oil ;)

Just bad luck I suppose. Hope Kole can't get me fixed soon.

First time I've seen the inside of a GP 61.....the cir clip design isn't good for that displacement size. Needs the con rod, piston and cir clip redesigned IMO

Just heard back from Kole [MENTION=2452]Limitless Aero[/MENTION].

He's sending me a replacement cylinder, piston, ring, gasket, and redesigned clips. It's all shipping tomorrow. Awesome service as usual... And with the redesign, it shouldn't happen again.

Thanks Kole :)
