Must be my estimates not in same ball park as others. In which case it may be time for some Eagle Tree on board system measurements. Should not be surprised if a few folks put their jet models over 10-G with their more energetic manuevers. A300ft radius loop with the bottom at 50ft above the deck only takes you up to 650ft. I know its not legal to break thru 400ft, so don't do it on my account

Cheers,

Phil
