Star Wars Patrol Boat (1/6 scale)
It never performed well as it was small and the six "C" cell battery pack weighted the boat down giving very little freeboard (about 3/8 inch) and a slow speed.
I decided to replace the 3000MAH 7.2V Nimh battery with a 2S Li-ion 3500MAH &.4V battery. Last Sunday I took it to the SSMBC meet and it went very well but after 50 feet it died. (It was the motor.) So that is now replace and it will be over two weeks to the next meet.
So, in the mean time I took some photos of the fix-up and "innards". In particular you can see the adapter I made to fit the 2S battery where the hobby battery sat. It is 3D printed. I placed the file on "Thingiverse" (link below) in case anyone else is interested.
I plan to get some videos at the next meet.
