Doesn't the new aircraft specs spell out what servo's you should use? Well, not specifically what servos, but what type of servo to use.

I will repeat what I wrote in another forum. Consider the Spektrum DX7 radio system. It uses the JR 821 digital servo and is expandable to include other aircraft. Other servo's will work with the RX. The main point with this radio is that it is completely free of inteference issues and can be operated no matter what other radio systems are being used at you field. And, it comes with four of the JR 821 servo's. (labled Spektrum, but they are the JR digitals.)
