further motor jots-
i forgot to mention the jaycar 50:1 545 motor/g/box
these are a good motor as well+a bit slow in revs , but HEAPS of torque +available in oz (not much is !!)
there is no reason why these motors couldnt be over-driven , to produce enough revs , say 1:1.5 , this has being done on another paddler from ballarat , and the boat is really fast and responsive +driving approx. 200 mm paddle wheel +2
