Yeah I purchased the tower transmitter. I did not know it was made by futaba, my mistake. I will plug the battery into the receiver and power up the radio and usually when I plug a servo in it will usually position itself in the proper idle posotion, but nothing. So I try to plug the servo in than turn the radio on, still nothing. I purchased 8 servos for my model, and I would say at best half would work at one time. And its to that point where i would not trust four of them with my life. The crystals are the same. 72.830. SHould just scrap them, and order some new ones.
