Hello Vince,
i have built the wiggly using scrap box bits there be no advantage using tank steering,,
its a stern wheeler so i would fit a rudder instead , and save a esc , a better turning controle , with rudder ,..
my grandson now as the wheeler which he sails with out , radio , just sticks it on fixed rudder turn ,
on the local pond , ……like a toy not the best stern wheeler,
but still its your choice have a look at the puddle ducks site loads of info on paddlers,
hope this helps cheers Larry…
