I would like to receive any and all feedback from any of you who know anything and/or have any experience with Aeromatic Propellors on Cubs, Champs, C-140/120 aircraft. I have a friend who has, I believe, a Cub of some model, with an Aeromatic prop on it and says it flys as if it has two different engines on it; one for take-off and one for cruise. I am going to see and hopefully fly this aircraft soon to see for myself but wanted to put this out to the community to see if anyone else has any experience with them. I am new at this posting and monitoring proceedure so I will try to keep this site up and respond promptly to any replies and if you need to contact me directly I'll work with that as the time presents itself. Thanks for your input.
