hello
I have had both and they are totally different ships. The 3 is larger and has a much better engineered wing. Both high and low speed flying are enhanced. The 3 can also be very easily converted to turbine operation. The 2 is small. Not good access to the gear in the nose and is simply inferior to the 3.
Spend the money on the 3 and you will be glad you did..
