I just got an old astro hog, that probalby has not been flown in 15 years. It currently has one servo in the center of the wing driving the ailerons. Is it worth it to try to modify that? The wing currently is attached with rubber bands, should I try to fix that, and if not what size rubber bands and how many? I stretched a couple 64's on there, but they seem very tight. should I use stadard servos on the rudder and elevators? I am thinking about changing the engine from an old 45 to a webra 61.

Thanks

Jon
