I am finishing a Dean's model of HMS Kelly. I would like to run each motor independent of the other, so I can reverse 1 while going forward with the other. Does anyone have a recommendation for what radio I should use? I have access to a Futaba Skysport 4 but it is set up for and aircraft so I would have to change the frequency. Can I do this myself or would I have send it for servicing?


Thanks

It is unlikely that a transmitter for aircraft use will be adaptable for ground use. I would suggest you opt for a 2.4 Ghz system which can be used for either ground or air. For dual prop control you will need at least a four channel set ( I don't think you can get a 3 channel) unless you fit a mixer on the throttle channel. The choice of manufacturer depends on how much you want to pay.

Thankyou!

You can do this with any 2-channel system - using a V-tail (Delta wing elevon) mixer from an aircraft & 2 speed controllers.

The rudder control drives the rudder servo & the differential for the speed controllers & the throttle signal works both speed controllers whether they be both forwards, both backwards or one of each. (you will need some servo Y leads).

The motor direction is derived from the rudder signal + throttle signal

forward & rudder central = both motors forwards
reverse & rudder central = both motors reverses
forwards & right rudder = left motor forwards, right motor reverse
forwards & left rudder = right motor forward, left motor reverse
etc.
