I am more worried about the actuators ot being powerful enough for the control surfaces. Is this normaly a problem? Thinking about it-I will probably build two planes one slow one with rudder and elevator and one "hot rod" with ailerons and elevator. I have flown several aero ace type planes and definantly want an elevator involved. OK so assuming money is not a problem what systems would you recomend? I am more worried about the radios than anything--can 72 mhz be used? I have tons of standard 72 mhz transmitters, but can I use them? Will they work with the micro receivers? What about constuction-balsa possible? I would hate to use foam but I guess I can if it's a must.
