Hey guys, recently upgraded to a dual 6374 motor setup and wanted some help as when I get toward the end of my throttle, it feels like one motor spins faster than the other even though the Kv 170 for both. When this happens I get deadly speed wobbles!
should I set a max erpm and see if that helps?
just need to see if anyone has expirenced this, I want to fix this before i end up in a wheelchair
You could check both motors kv. connect the pc to one vesc and enter in the terminal command “kv”. connect to the other vesc and repeat the step to compare the value
It’s unlikely that 1 motor is spinning faster than the other, possible but unlikely. I would look at your bushing srtuo first. Go look the Riptide/@Alphamail, he has dozens of recommended setups.
ive been riding evolve for years, the board that im having the issue on is a pimped evolve gen 2 so i have kept the evolve trucks and everything, just running dual 6374 and focbox with 10s4p vtc6 (120a) its a beast.
Its not to do with my stance i dont think i was riding 45kmph comfortably with single drive so its weird
Without a doubt this
Upgrade your bushings and pivot cups to a harder duro and see. Riptides are your best bet but evolve do sell a full set of differing duro bushings too.
You will not believe how much a proper set up will help with speed issues. It certainly is not the motors spinning up differently. When you accelerate on an esk8 the trucks walk if the bushings are bad.
Evolve trucks are much more prone to in ones because if the double kingpin.
Wobbles are caused by vibrations from outside forces (outside of the truck). The addition of another motor is creating a combination of vibrations that start the wobbles at a certain speed.
A bushing upgrade will keep the vibrations isolated to a degree, but this trucks will always be prone to wibbles.
I feel ya. I like the carve of DKPs but not the lack of stability at speed. SR TKPs are at least as carvy and much more stable at speed. The bushing seat replaces the 2nd kingpin, does a much better job.
