I have a w.029 brandenburg that came with floats and recommended electric power plant. I ended up putting a .40 nitro on it and full size servos so to say it’s a bit heavier is putting it lightly. It sits in the water pretty much 3/4 of the way up the floats. I’ve already pumped foam into them but still same. My next move is to add to them. Any recommendations on whether or not I should and or if I should make them deeper or add length? Any advice would be appreciated thanks.
