I like single speed gearboxes better for some reason. the tan B-36 gearbox is good but the gear teeth are very small (1st counter gear) and can get broken with some wheel hammering. the MN gearbox with a 280 swapped in place of the 260 makes lots of torque, my very overweight D-90 sure needed it. the 4.00 ESC's are OK with a 280 motor, but not enough current for feeding a 380 motor with a load on it, especially in reverse, is about half of the forward output power. not tried this with these little ESC's, but it did work in a full size electric runabout I'd built, used two 12V 60A ESC's wired fully parallel, battery, motor, forward+reverse switch, and the speed pot. the pair of ESC's shared the load no problem, where a single unit would get hot after 10 minutes of running, the pair only lukewarm after 10-15 minutes full throttle with a passenger aboard... they were running a #36 Minn Kota trolling motor, with a slightly higher pitch 3 blade Kipawa propeller on it. different situation for sure, with different rules.. (displacement hull "rule of squares": square root of hull length times 1.56 = max displacement speed, 75-80% of that being its best efficiency. voltage and current told the story, it cruised best at 2/3 throttle, 4 mph. top speed was only 5.2 mph but pulling twice the amps.) not tried it here, but it may be possible to stack+wire a pair of the small brushed ESC's parallel the same way, for driving a 370-380-390 size motor decently.
Good job the 2-speed gearbox is great
🔵🔵🔵👍👍👍😀😀😀🔵🔵🔵
Yes I'm a big fan. 👍👍
Excellent video
Much appreciated. And thanks for dropping by! 👍🙋
Great conversion and programming, nice run
Thank you very much. Thanks for taking the time to comment! 👍👍
Nice wpl,, 😍😍👍
