Do you think the .55AX can pull a 7 pound Phoenix .55 size F4U Corsair around pretty well? .55 is supposed to be the top end of the Engine Range, but the darn design (too much Plywood) is requiring the builder to add a lot of Nose Weight up front in order for it to balance. I'm hoping that if I move my RX Battery Pack behind the Firewall and scoot the Servos as far forward as I can get them then maybe I won't need to add that much weight in order for it to balance correctly.
