Hi Matrix,

The boat you chose is a fast electric, which steers very good when running at speed, hence the small rudder surface.

Making narrow turns with a catamaran at low speed needs a much larger rudder, which will have way too much authority when you run the boat on the plane. The rudder throw must(!) be reduced than, or you'll risk flipping the boat.

A simple way to acheive this would be to mix the throttle and the rudder channel in such a way that the rudder throw is decreased, as the throttle signal is increased.

As a side note; a catamaran is very reluctant to make narrow turns while crawling, due to the hull design.
A monohull will do a much better job at that.

Regards, Jan.
