My neighbor gave the motor to me as well as an old trailer door . I used the wood panel for the hull . I already had the radio and servos from an old airplane . I made the steering mechanics and engine stand from window frame parts , cd player parts and sheet brass from an old fireplace cover . It sure looks like it will work , I hope it remembers it"s a boat and doesn't think it's an airplane !
I measured out the two largest good pieces of panel to come up with the overall dimensions .
From the output shaft of the motor I measured out a triangle that would allow propeller clearance to get overall width .
Then I basically pieced everything else in from there out either existing or hand - made pieces .
From there I used pieces of card stock and bent them around the wierd curves and angles , I used those pieces as templates for the actual wood pieces .
From there I just kinda eyeballed every thing .
