just sent you a P.M. about servos but I will answer it here also for the TF 60 size planes any standard size servo will do just fine such as the Futaba 3004 ball bering servo it has plenty of power for this size plane and is not to heavy.
TF planes tend to be a bit on the heavy side there well built and if you compare them to a Hangar 9 there tanks that fly.you don't need any thing more powerful than that for your plane for sure.
