Greetings All

Are there any AMA, FAIor MAAC rule gurus here who can tell me if using a chair while flying competition is allowed? I have quite a bad balance issue (certified) and it would be far better for me to sit while I fly instead of weaving around like there is a 100kt wind blowing. I do think that this would improve my flying although I have not tried as of yet. I did not want to get my hopes up if it was legal in competition or not.

Thanks for the input,

MJ
