RE: bvm super balsa bandit
I agree with averything Harley, the creator of "Egyptoids" [&:], has said. BTW, The Balsa SB was also designed for flying at higher altitudes like CO.
But I think the P80 would be a better choice than the P70 IF you decide to go that route. There is only a few oz of weight difference btween the two.
The Original Bandit was flown with an 8-10 lbs DF, I think the PST600 would fly it fine and it will do 180 mph flat out (the DF did 180mph easily).
For a 1st turbine jet, I do not think the SB is the one UNLESS you have someone guiding thru the building and flying process. Like Harely said, a King cat may be your best bet due to its light wing loading by design and the cost is very close with less building time!!!
