Gingyer - no pics as yet - maybe someday.
DickyD - as the old saying goes, "Quality is cheap"
I have a set up that is reliable and performs very well from extremely slow speed with just two props turning over slowly to where the boat is planing. As for cost, well it had to have 4 motors and the Graupners are reasonably priced, the relay and circuit breakers are cheap, I make up the cell packs myself from a cheap source and I really don't think the componets from Action Electronics (Aka FLJ) are overpriced.
Apart from the batteries, motors and speaker, I actually have all this mounted on a sheet of 6mm perspex that is held in by a single screw and two peices of velcro tape. I simply unplug the batteries, speaker and the 8 way connector block to the motors and it all lifts out through the hatch - tight but manageable.
