according to my maths, with 4, 91kv direct drives and 120mm racing tires, 12S and 60a battery limit per motor, over 50mph can be sustained on a 35% grade.
Not many people actually go up 30 degree hill. Usually, it’s about 20-25. You can see an example here https://www.youtube.com/watch?v=tEEgINoP2-o
But you could easily power up over the hill 20+ mph. Probably more but a face plant on a hill is worse than a face plant on a regular street. I’ve probably only ever gone about 20-25mph uphill but that’s because I ride like grandma. I’m sure others have went up faster.

No way mate. That is because we are sensible and humble e-skaters

Okay then. TORQUEBOARS 90KV DIRECT DRIVES it will be.

@Alvin They ride a 4WD 90KV TB DD. @Tello1969 @Kellag They said it pretty much almost keeps up with 4WD Gear Drive setup.

I also recommend upgrading your remote from a flipsky vx1 if you want to that speed.
Or at least i would, not sure about others
Like the OSSR,Hoyt, or maytech r2 waterproof remote. You could always start with flipsky and see how you feel but with that much speed i would get a remote with more throttle range

Do I need a loopkey like this one.
Because the 12s4p battery does have a on off switch.
12s4p has a built in on off switch so you don’t need a loop key or on off switch separately.

Okay, is it a cut out for the on off button in the enclosure that comes with the battery?
Yeah

Yes for sure we got the set up and the location to really put these to the test I’m sure they’ll do great

the steepest street in san francisco is about 32% i believe, which is about 17.7 degrees. a 30 degree slope is actually about 58%
so the 4, 91kv direct drives with 120mm tires, 12S and 60a battery limit per motor could theoretically sustain over 50mph on a 35% slope which is about 19.2 degrees, or steeper than the steepest block in san francisco.
degrees is an angle where as % slope is the percentage height gained versus the horizontal distance traveled, so 32% would be 32 feet height gain for 100 foot horizontal travel, or about 17.7 degrees.

Hi I recently received my Tampa wand remote with preflashed NRF after installing 1.19 of vesc tool and updating to the latest firmware. I can’t seem to get my remote to sync with the VESC. I’ve reconfigured the motors, no problems everything fine. Then when I go to configure input I don’t get an option for my vesc, though its only a single vesc so im not sure I would. When I try and pair the remote I follow instructions and it just doesnt sync. The only thing I dont know is if 4.12 vesc specifically Tourqueboards one is NRF capable Trampa couldn’t give me any solid answers on 4.12 compatability with the wand despite me checking prior to purchase. does any one know if 4.12 is nrf capable or if they might have any suggestions or first hand experiences with the wand.
@Alvin suppose you had only (2) 91kv direct drives (instead of 4) at 12S with 60a battery limit per motor, and you wanted to know what wheel size gets you up a 35% slope as fast as possible… it works out to 75mm tire diameter for 32.5mph on 35% slope / 17.7 degrees.
