However, I will have two flyable planes. If I transfer engine and electroncis from first to second plane, only one can fly.
Just understand that the cycle doesn't stop at plane number 2
I have 6 OS motors that are 18 yrs old and have been in many planes same goes for my electronics my newest tx is 4 years old and been 3 planes. I have servos that I bought with radios that are no longer legal but I still can use the servos.
My point was and is that when you justify the price of that type of plane you need to realize that the entire investment is for that one plane only. If you go the route I suggested you can re-use your gear. This simply makes your initial investment go farther.
