RE: U.S. 41 ?
Ed,
I had the same engine in the same aircraft. Great combination. I ran mine with an 18x10 or 18x6-10 with great results. The suggested 20x8 should work as well.
If you will send me a PM with your email address, I will send you a copy of the manual. Ok, it is for the Quadra 42, but they are the same. I have both engines.
Have fun with it!

RE: U.S. 41 ?
Thank you guys, you have been very helpful, and I have one remaining question. I have one terminal protruding from the magnito coil, is this where I attach my Kill switch ? And just how important is it that I use a kill switch ? Can I fly the plane without one ? ( whoops ... that's 3 questions isn't it ? [] )

Thanks w8ye. I can now turn it off using the throttle from the transmitter, or by choking the exposed carburetor . The kill switch would be a 3rd way.

RE: U.S. 41 ?
Ed,
Grounding the coil to the engine case through a switch is an important safety feature. I use a good size toggle switch on the forward side of the fuselage that is easily accessible. You never know when you will need it. A remote kill switch is even better, but I have to admit I generally don't use them (part of being cheap). I wished I had one some time back when I had a runaway engine. Stuck on full throttle. Handling was not a problem, but my endurance was. That little 21cc gasser didn't suck much fuel. The problem started about 5 minutes into the flight. About 45 minutes and one relief pilot later she came down uneventfully deadsticked. In today's commonly over-powered birds, a stuck open throttle might be a much bigger challenge to handle - safely, and survivably.
Have fun,
Bedford

RE: U.S. 41 ?
I would like to convert my US 41 to electronic ignition but have been having trouble finding a conversion kit for it can anyone help here. Tried CH but no luck.I need the flywheel and pickup bracket. Also what are the rules about kill switches for cdi engines and mag engines .
