Ali, that is a very generous offer. Thank You! I don't have a 3e yet but I do have a Demon Cortex in my ESM PC21 from Troy Built Models. It hasn't been flown with the gyro yet but I expect to ring it out during the upcoming season. However a 3e is in the future for my Reaction X and likely my F-22. When Maine Jets comes around I'd like to have you check the systems out.
