Ive built several bait boats now and each time i complete one, i seem to want to build a better one.
my next plan is a cattamaran hull with twin motors, but this time no rudders, i.e. i want to use indivdual motor power to steer left or right. so my question is whats the best way to do this? do i use two speed controllers with a 3 channel radio steering it like a tank or can a two channel radio be used with some sort of mixer?? cheers for any info

2 channel radio and a P94 from Action.

thanks guys that looks like the kiddy, quite expensive though at £76 !! does anyone know of other cheaper brands or second hand or wants to build me one for a pound, lol

Not that expensive when you consider it has two speed controllers and four different mixers.

ok guys, so if i had a couple of esc's lying around would it be a case of just getting a v tail mixer from mtroniks, if so how would this work, is it just push stick left and left motor works push right and right motor works? im assuming that it wont be one motor pushes forwards while the other reverses, can anyone shed a little light, cheers

[lozvik]

does anyone know the answer for the above question, cheers

From memory, having seen one working on Dave's stand at a few shows, the further you move the steering stick, the bigger the difference in speed.  Eventually, the "inboard" prop reverses.  If the boat is not being driven (ie throttle at zero), the two motors drive in opposition.
