Hey I’m trying to build an electric longboard as cheaply as possible, but would like the option to upgrade in the future, so my current plan is to have 2 3S 5000mAh 25C batteries in series, a 6354 260kV motor, and this ESC. I will also use a 36:16 gear ratio. If my calculations are correct this should give me a top speed of around 18mph with relatively little torque.
In the future I would like to get another motor/ESC and go dual drive, at this point I think I would change the gear ratio to something like 36:20. This would raise my top speed significantly at the expense of torque, but from what I understand that loss would be easily outweighed by the gained torque from dual motors. Is this correct? Is there anything wrong with running this kind of gear ratio?
I’m trying to keep an 6S setup since ordering a VESC will cost me about 150$ and the one from hobbyking is a third of the price, on top of that I get to pay less for batteries. I figure if I can achieve a top speed of 20-25 mph with a single motor 6S setup at the sacrifice of torque, I could fix that by adding another motor and I would be able to build a dual motor 6S board for the same price if not cheaper than something using 8-12S. So I guess the question is, should I save up and go for a higher voltage build? Or will my current plan suit my needs?
