Using crashed equipment from totaled out airplanes is a " Bad" idea!
"You mean to tell me",,, thats a crashed Rx in your brand new plane? ( I'll let you finish that one
)
The chances of your new plane or the backup plane surviving the next flight are perty slim.
Spend the petty bucks,,, send it in and have it checked out.
