New here. Had a few small battery controlled planes but it's been a long time. Not long ago I purchased my first CG Super Chipmonk kit from 1988. The manual says to use a 4 channel radio. I have never purchased radio controller with servos ect. Can anyone steer my in the right direction of what's the best radio equipment I need for this Chipmonk? Could I go with old original that they sell on eBay?
