I can let it run free but there is the metal pushrods on either side of it for the rudder and elevator and i dont want it to touch them.. as metal isn't the antenna's best friend..the only thing i can think of is to fix it on the bottom of the rudder with enough slack between it and the fuz to allow movement without damageing it.. i've done this on a previous plane and it was okay i just dont want to drill any holes in the rudder.. I'll have to come up with something.
