Differential thrust for seaplane, Futaba T7C
Hi there:
I have a MR. Aerodesign CL-415 water bomber that I would like to set up with differential thrust to ease in water taxiing.
The plane is currently flying with one ESC hooked into channel 3 and the second ESC hooked to channel 7, I have used a P-mix to slave the second ESC to the first (channel 7 slaved to channel 3).
After landing I would like the ability to throw a switch and then have the throttle functions linked to the rudder. If I input left rudder I would like the right engine speed to increase ahead of the left engine with throttle application so that the plane will steer to the left. The opposite for right rudder input.
Can this be done with the 7C radio? If so how?
Thanks for the help, Terry.
P.S. there was a thread on one of the discussion boards about a fellow who did this with a Spectrum 7 radio, but I can find the link at the moment.
Here's that link to the Spectrum discussion.

Yes, this can be done with your 7C.
The set up for this is basically just the way he did his in the link you provided.
Since you already have the mix set for your throttle channels, you will simply need to do two Mixes for the rudder.
The first mix will be set up with Master as Rudder and Slave as Throttle. I did this at my desk and set this mix to switch A at a rate of 50% both ways.
Next you'll want to set a mix with Master as Rudder and Slave as CH7, this mix I put on switch D and set these rates at 50% both ways.
Now my twin throttles work together with no rudder with both switches in the up position, but as I flip either switch the motor on just that side is activated with my rudder.
