On going build, yet to fit Fire monitors and sundry over fittings, first launched 19th March 2013 at Etherow Park, Stockport. initially using a 25amp speed controller, found very slow and stuttery a little disappointed, but all went well on up grade to 50 amp and change to 2 blade racing prop, at lakeside, reverted to original 3 bladed prop after altering angle of blades to same as twin bladed prop with little loss of speed, did think of fitting two motors, but well pleased with set up as is, steers well forwards and in reverse unusual for a single prop.
