Cattermaran controller water cooling control trim control and throttle up ramp to reduce stress on the drive train, and reduce battery drain from harsh acceleration burning up Amps because of Inertia.

Arduino nano captures 4 channels from an HK 6CH RX and an HK-T6A-V2 transmitter. Simplest code I could write

Very simple bit of code no interrupts just pulseIn() and noInterrupts() and the servos don't jitter any more than they do on the RX directly. If you want to hack the RX have a look here this guy seems to have a plan.
There is a wee mix on ch5 pot and elevator done in the code so the pot sets the base trim and the elevator lets you adjust the trim quickly. Will be adding a RTC and a DC water pump on a 20A Turnigy brushed ESC for cooling control. If that goes well may use a hall effect device to monitor current and see if I can implement torque control with overspeed limiting, I think torque control will reduce shock loads when the prop looses grip in the surf.
This is the sketch as maidened with a throttle limit on one of the aux pots
