Bought secondhand with original servo on/off power switch, removed and fitted proper motor esc to give better motor performance and handling, especially when turning.After having an uprated/modified flexI drive made, I have had to replace the original brushed motor with a brushless unit. The space needed for a suitable bigger brushed motor would not fit within the confines of the original outboard cowling. So heres fingers crossed!-- An update when pool tested.
