I’ve just been struggling to work out gear ratios. I know big wheels and high KV is already quite a lot of speed but would the other motor bring my torque up to a reasonable amount if I have a 15 to 36 tooth reduction for example?
I have had a look on Esk8 calculator and is says with this ratio, I should get a top speed of 30.99 mph. But I need to know if I’d get enough torque to have fun?
You trade torque for top speed and vice versa, you certainly would not have the ‘gripping’ torque you think you will if your top speed is 30mph with 260kv motors. Look at the motor above and take his advice, hes trying to ensure you wont spend twice. weve all done it
The big problem is that you are running 6s, or about 20 V. The motor can’t handle much more than 60A, 20V * 60A = 1200 watts. That’s a little more than the Chinese boards, but not enough to make it worth the time, effort, and expense.
In diy, the most minimal build plan that makes sense is imo 12s, LiPo, single 6355 200 kv, chain drive, geared to 25 mph. Otherwise it usually makes more sense to buy a Chinese hub motor board or a used boosted.
I’d be using dual motors so hopefully less current would be drawn. I’d upgerade to 12s VESC’s when I can afford it too. So 12s (44.4v) * 70A MAX = 3108 Watts which is kinda reasonable. Obviously, I wouldn’t be running 70A continuous, more like 30? Only 70 maybe starting off.
You’re gonna want caliber trucks at the very least.
If you go with the normal calibers 6364 wont actually fix next to each other.
But you could have one facing forward and one backwards.
Or
Buy @torqueboards 218 truck (basically a longer caliber truck)
Then you could mount the motors next to each other.
