I know that since it is a trainer.....I won't be able to do much with it. I just wanted to find a propeller that will take my plane to it's full pontential. My plane is a Carl Goldberg Eaglet 50. It's about a 5-6 year old kit....but a great trainer. The flying weight is: 50 oz. I have set up with 4 channels. Like I mentioned before....I know that it wont do any spectacular stunts......I just want to fly it to the limit (Ok.....well not that far....that wouldn't be to safe) Thanks again for the help
