Whoa, are you talking about the Parkzone fighters that run 130 bucks per setup?? You do realize that there is a LOT of touching going on in combat, touching that will inevitably end up destroying planes.
BUT you could build some electric combat planes that are designed for combat, both in streamer pulling, maneuverability, controllable flight speeds AND cheap replacement.
Things like these:
Simple Foam Delta Wing, for fun or...COMBAT!
and
WWII Combat planes
and
I'm also missing the flat ones but I think they're on this forum.
