ACTion has the answer. See dealers. Pete M

I don't have this transmitter, but most modern computer txs have good mixing built in, so you shouldn't need to buy an external mixer. Basically need to mix throttle and rudder channels. Might get a better response on a model flight group where this tx is actually used.

A problem that you can find is that the inbuilt mixing is geared to aircraft use and is of limited functionality if you want to apply it to a boat unless you use the sticks in other than the normally accepted manner for marine models. My Futaba 6 EXA is like that.

My 9 channel JR aircraft tx has several free mixers, so you can mix any channel with any other. All computer txs I have used over the last 20 years or so have had at least some free mixing.
Mind you, I haven't tried this in a boat as yet, but have a twin-screw kit on the way, and will buy a new radio for it when I've built it, so I might have to eat my words :)
Quick thought after posting ::) Some of the aircraft txs have a 'twin engine' mix built in, which would do exactly what you want, mixes two throttle outputs with the throttle and rudder stick. You might need to change modes so that the radio knows the rudder is on the right stick if that's how use it, as most come as mode 2 (throttle and rudder on left stick) by default.

What model Futaba is it?

I think with the 7C you have to use Heli mode which has 3 programmable mixers.
