Can I use my old heli controller?

Can I use my old heli controller and receiver 35mhz on a first drone build? It’s a robocat with a cc3d.

Yes I am sure you can use this as long as your receiver outputs PWM on each channel which I think it will.

Although it would be best to upgrade to 2.4Ghz as you progress more with quadcopters system as its much more reliable…
