Some months ago I purchased a 28 inch fibre glass shovel nose hull from Johnny from, head of the river. I have a Feigao 10 xl brushless motor for it, the max current = 66A. The question is what size and make of water cooled ESC should I get.The hull weighs 500gm.This isn't a rush job, as for Iam getting together another 25 inch classic shovel nose which I got of e-bay, but that came complete, - radio gear. Cheers Wayn.
