Been away from the hobby for about 20 years. Going to build a tri-copter to play with. How is it that Turnigy and others radios are so much cheaper than say a Futaba (which was my favorite radio back when)? Are there that much differences in the radios? I find it hard to believe that a Futaba 6 channel radio is 169.00, and the Turnigy is 50.00. Makes no sense to me, what are the differences? Sorry to ask such basic questions, but the hobby has changed drastically since I've been away!
