Id suggest getting a perfect tune on the stock muffler before you worry about the canister. Setup a throttle curve in the radio to spread the power evenly.
As we mentioned, you don't need to add weight. Quit messing with CG on the ground, and go fly! Get all that weight out!
Thanks Gyro i will try without weight than.
Can someone point me to a tuning for dummies or some simple steps to do to be sure the engine is well tuned? I'm asking this because at my small field there aren't many people using gas plane and no one have big experience with 50cc aircraft. :crying:
Also for Th curve do you use and expo curve? how do you find the right amount to use? The middle stick = 1/2 rpms? :facepalm:
thanks
