Just bought a tug last weekend from ebay, the guy had built it from plans. Single drive motor runs with 2x 6v batts, run it once an was slow i no there not fast but it was slow. Sorry have no idea what motor it is but looks like a 540 stock motor ???. I might up grade it any one no what i should but in it i normal run fast elecric so there no good but something torque an fast maybe?

also any idea the scale its 18inc long-8inc wide-14inc tall?

thanks chris

I just built a Springer to the same dimensions using a 540 motor and it moves very nicely through the water. Its not meant to be fast.
If yours is really slow perhaps its the prop that needs looking at. I use a 4 blade brass 40mm prop.
You can find loads of info. on this site for Springers.
Good luck

That looks like a tidy Springer. Try another prop, that looks like a racing two blader ( coarse pitch.)   A brass (worth the money) three blade of 40mm max dia. might transform performance. Make sure the rotation suits your set-up ie right hand or left hand pitch. Check speed controller is programmed correctly and you can get full throttle.  Move batteries back till waterline is half inch up at the bow. Consider making a regulation sized rudder , square brass sheet soldered into slot on rudder post where the rivets are, (they can be filed out easily) . Take rudder out to solder square blade to post. Add foam insulation/floatation to all spare space, bow, stern. Dont ask why !!!!!

I agree with the prop, that wouldn't pull the skin off a rice pudding, but a nice brass jobbie, try prop shop, Simon is really good to talk to, he has probably got a prop specifically for springers. and also fit anothe pivot point on the bottom of the rudder and fit a skeg from the keelson to the bottom of the rudder, it will make it a lot less vulnerable.
