I just flew my Wonder this morning and it is sitting close to the computer so I can give you my wthrows. The elevator throw is between 3/8 and 5/16 inch measured where the elevator is 1-1/4 inch wide. The ailerons move 5/16 inch measured where the aileron is 1-1/4 inch wide. Not sure how this compares to instructions. I kept the bulky wing tips on however I believe I hollowed them out some, not sure, I know I have a steel screw in one for balance. Mid twenties will be tough. My fuel tank is not round, it is squarish with a slanted front. The fuel tank installation is a challenge.
