RE: new f9 panther at hobby-lobby!
The servos are already installed. What I use on the bottom of my planes that I belly land ... are pieces/strips of the self-stick protective sheets that the RC car guys use on the bottom of their cars. I think this stuff might be made of mylar .... it is very strong ... I even belly land them on asphalt. Tower Hobbies has it (in the RC car section). It is made by Associated. Bob
