... It is similar to the function backflips on a powerboat. u needs to trim these flaps for smooth running high speed.
And the bast ist they will be adjustable. I had also stick transmitters in the past. In Germany that was highly regulated which frequency you had to use for surface (27 and 40Mhz) or air (35Mhz). My surface TX´s had no mixing functions but my TX for 35Mhz for planes.
Than I modified a Graupner MC22 ( I think in USA they caudal JR) TX with a Jeti module for my airplanes and tried to use them also for my powerboat.
When I started, I let move the flaps upward to get faster in gliding. I can not better explain.
While the boat comes up with the back, the mixer moves the flaps more in lower position to "push" the front more to water surface and keeps the prop in waterline. Also I used the right stick for separate trimming. (The left for throttle)
Mainly you can use a mix for you´re function but you have to make a setting to overdrive that.
I think that the CR4T or their clones can handle that but just with the three buttons below the steering wheel.
Trim button for trimming and.override and the push button for switching the mixer on and off.
