Soon I will be building a 4WD MTB board (9inch tyres). I’m going to run this at 20s. Now I am looking for motors, but I want some input from the community.
The motors will be mounted on the Finality AT Gear Drive. I still have the option to go for 1: 4 or 1: 5 and 8 or 10mm axle (but I prefer 10mm).
I’m thinking of going for 6364 or 6374. But I don’t see many options to choose from.
This APS motor has my interest, 130kV would give me a speed of 70km/h. But I am looking for alternatives…
After seeing this geezer, I’m wondering whether there could be any practical need to go bigger than 4x 6374s. Just getting the most out of those alone will get you through 4 new soft, wide tyres every 100 km and you’ll need the core physique of a Greek God.
Whatever happened to those ReacherTech motors? I think @3DServisas was messing around with them. Can’t remember who else. Are they up to scratch?
def following - would love to know how many A you plan on running through the stormys at 20S and why
edit - gotta be honest you might wana use a diff motor than APS - I’ve broken quite a few, and while they do replace them, it takes weeks/months sometimes.
I’m not at a computer so I’m not going to do the maths…
But gear it high, as high as you want.
My 4wd running streetwing (may tech) 6374 motors wheels pins very easily on roads, despite being geared as the following.
12s battery, 190kv motor, 15/58 (I’m pretty sure) on 8 inch tyres.
Around 42-45mph with no rpm limit (but of course there is one)
In the video I was running 7inch tyres.
So yeah, if using it for onroad gear as high as you want, could likely get away with 70mph and still break and accelerate faster than an evolve (not that that is saying a lot though)
If going for off road, I would gear for 25-30mph, and not worry about really high power motors. Even the old trampa motors at 2400 Watts would be suitable.
