though Sub sinker recomends a thruster, I have found that just on rudder alone, it has a respectable turning ability, able to swing round quite nicely for a vessel of its size, using her two thrusters, it can be made to spin on the spot, crab sideways, and be able to manouvre in confined spaces.

I have a prop-shop 5-bladed propeller fitted to the shaft, and it made a BIG difference to the performance, making stopping the vessel in crowded waters MUCH easier, as the prop has better bite.

I recomend a Futaba Skysport 4, 6EXA, F14, on a surface frequency, or Spektrum DX6 or 7 / Futaba 6EX on 2.4ghz.
