Yes the price is great but they will not work on my Futaba 7C 2.4. There is a problem with the servo going full 90 degree when you turn on the receiver. It takes millect to bind receiver to transmitter. There is some electrical differences in the way HD servoes are made and Hi Tec, and Futaba. So far I have no problem with HI Tec servoes or any Futaba servoes. Do any of your friends fly Futaba 2.4. If so please ask them to check out your servoes . This will not hurt the servo it just turns 90 degrees and then goes to center.which then it works great, It sure would tear up control surface while it binds to the transmitter though. This could answer all my questions on the servo.
