Another guy in our local PRA chapter was trying another route for same gearbox (Rotax C) & engine, but the fellow he paid to waterjet cut the parts did not do a good job, and ducked responsibility to correct the mis-aligned holes...
Couldn't have been me, I never sold anything to anyone in Oregon, PRA member or otherwise, to the best of my recollection. I do have a customer in Washington for a YG4i (Apex) kit, but his order has not shipped yet and he is a FW guy, not gyro clubber.
Hey guys, about using the Tango YG3 adapter, just a word of caution if I may: Tango uses hollow Luga props (also sold as Kool Prop), which are found on many eurotubs like MTO, etc. A prop strike with a hollow Luga prop is no way to prove adapter strength - it is more like a hot knife cutting through butter, near zero resistance.
Put a Warp Drive solid carbon fiber prop on one of these things and you are asking for trouble. The rotating inertial mass of a WD is far greater than a Luga, and that means a lot more stress on the attachment points of the adapter, etc. My advice to anyone using the Tango YG3 adapters is to stick with a Luga prop, and you should be OK with that combination.
Luga props were rated for 130 HP, so not enough to stand up to the muscle of a YG4, let alone a YG4i. They have a new product that is rated for 170 HP now. I am a dealer for Warp drive, Luga, and SPG gearboxes. I may try to become a Whirlwind dealer, and have received the info for Pezske as well. Prince is just to expensive, I'll never go that route.
Anyway, happy Fourth!
