    Hi Roy

    I can confirm that the one I recommend you get 100% full throttle though I ditched the differential only setup after a painfully twitchy 10min of run, stop, adjust of the manual rudder and added in a working rudder alongside the mixer which made handling a breeze

    Regards

    Hi Happy H Do you know if the power to each motor is 100%? Many years ago I built a mixer electronics kit and the power was shared 50:50 never getting full speed on both motors.

    This is what you need. It's a mixer for rudderless boats. One lead plugs into channel 1 and the other channel 2. The other two leads connect to the 2 esc's and then that's it as it mixes everything accordingly for you. Just make sure you have a right hand and a left hand propeller or the boat will try drag itself one way or another without a rudder to counteract that. That's why you'll always find a small manually adjustable rudder on the differential boats

    Kindest regards
    Scott

    Thanks you all for your help, I think I get the picture
    The tx I intend to use will be a very simple basic one no bells and whistles.
    The boat will not have a rudder, steering via motors only.
    I would woukd like a setup of two stick tx left stick for forward and reverse / speed.
    With right stick controlling steering via motors.
    In this case what is the simplest/ best configuration.
    Many thanks

    I should have mentioned that you can find Andy in the Boats section, both on "Dock Talk" and "Scale Boats".

    PS1,
    There is a gentleman who hangs out on RC Groups, (www.rcgroups.com). His name is Andy Kunz and he is a factory representative for Spectrum. I would suggest that you attempt to contact him and, having your radio model available, explain what you would like to do and ask him for his input.
    It is entirely possible that your radio will allow you to set up mixing to run the motors without having to purchase additional electronics.
    Apologies to the moderator is I am violating protocol here.

    I don't know how to set that up via Spektrum however I know that you can set it up within a few seconds on a transmitter I use. You need two esc's which plug into channel 1 & 2. The transmitter does the mixing for you. It's a Surpass Hobby 6 channel wheel & trigger transmitter and receiver which are available from Amazon at Β£37. Receiver range is approx 350m and it's proven very reliable so far

    From what I've read it's very difficult to control two motors with separate sticks apart from at very slow speeds.

    Better to use one of the mixing boards mentioned - Action Electronics do them and Component Shop supply them though they are showing as out of stock at the moment.
