RE: Dave Brown in Feb04 Model Aviation
Volture,
I know you didn't ask me about the recommended VNE for the AMA's max speed but I'll give you a good starting point....Go with the manufacturer's recommended VNE. For example: VNE on a BVM Composite Bandit-250MPH, VNE on a Composite ARF Rookie-200 MPH, VNE on a BVM BobCat 175 MPH.........To tell you the truth, most guys adhere to the manufacturer's recommended VNE anyway.
As far as a weight limit---How about 50 lbs dry. All along we have stated that there are 55 lb (wet) 40-50% aerobats that only carry around 2 liters of fuel. They don't need to carry much fuel as they are pretty miserly compared to jets. At 50 lbs dry this would allow the jet to go over 55 lbs when fully fueled at takeoff but be under the 55 lb weight limit upon landing.
Your last question just requires common sense----If you have to ask if it is risky then it probably is.
