Hey david and please allow me to welcome you to RCU. Indeed your Telly looks like a fine job. I still keep a tired old Senior around for an occasional glider piggyback launch.

From that tell tail muffler your engine is likely a fox and I am guessing maybe a .61. I must say I agree with propworn (dennis) above about that monumentally oversized paddlebladed three point prop. Even though your engine may be larger (over the forty recommendation) I feel that the prop is going to present you with running problems and a loss of inflight reliability.
