Ever consider going wtih one big single. I think if you go fast enough with the duel drives you start to cavitate at speed due to the hull running too high (surface drives). I'd switch to a single motor single drive with an offset rudder. Searching for hardware is kind of painful. Look around on ebay and post the links here of what you think might work.
id really like to stick with the twins due to the fact that i already have built the whole thing with the exception of the drives. it already has a pair of brushless systems in it, octura props, water cooling, graupner u-drives........etc
i just like the idea of the twins
