Thanks, will check it out.
Would still like to solve the live telemetry part, so I’m holding off on the puck for now.

Replying to this comment because of conversations I’ve had with other vendors. The motor color only slightly changes the amount of heat in the motors. The biggest thing that I’ve seen with motor temps are losses like copper/iron. I just wanted to update myself there😂.

If you are going for a ride in the blazing summer sun, perhaps it could make a noticeable difference. I assume the coolest motors would be mirror finish, as those would reflect more sun than even white would.
This guy compared the same model vehicle across several colors, (FLIR camera measuring hood of the vehicle) and the difference is surprising:
- white = 112f
- silver = 129f
- black = 159f

Maybe for a stale environment like a car but reachers or a lot of motors in our case have air constantly flowing through them. I’m not saying you’re wrong, it’s just another aspect to consider.

The measurements were taken on the hood of the car, not the inside.
I’m not saying it’s going to make or break your motor thermals, but color has a surprisingly large effect, at least in the instance of a vehicle paint job.

Proud to say that I can finally call this build “done.” Lots more I would like to do, but I might explore some of those ideas on a new build. Thanks again to all that helped out with this build! Super happy with how it came out. More footage incoming in the new year when things warm up.

How does it ride!? How does it feel? No grip!? Madman.

Good questions haha
Tons of torque due to the HV, high gearing, & low kv. I limited the total battery amps to 80 iirc so that I can ride without being thrown off. (Also added an ERPM limit). Have gotten to ~37mph, nothing faster yet. Bike trails are bumpy here in the windy city, and so am being cautious. However, the Jotnar’s wide riding platform & large drops allow for (some) peace of mind at speed.
I considered making it 4wd so that the available power wasn’t so concentrated at the rear, but it is already quite heavy & $$$$. Also, the battery-VESC wiring harness would need to be redone to add 2 plugs for the additional Tronics.
I have had good results with the Qinds, and they grip well. Hopefully BKB/Landsurf/etc develops a esk8-specific 175mm+ flat profile tire. The BKB 150s are fantastic, but too small for this board.
Also swapped in softer bushings than what I originally used, and as a result, it corners very well. Considering a Sabre mount or some more custom laser/CNC bits so that I can record ride footage.

Also, will add that I’m not too sure what the top end is, only because I’m afraid of blowing the Tronics (exactly 24s rated).
Speaking of the wiring harness— no issues with Hummie’s antisparked QS8s. I think the QS10s are a bit overkill for this setup, and the Tronics come preinstalled with QS8s anyways.

Top end is usually around 85% of unloaded top speed. You won’t blow anything up spinning the wheels to top speed on the bench.

Yes, good point. Still uneasy about voltage spikes, but they aren’t that big of a deal. I do still have to watch out when braking though (no regen).

What KV are your motors?

You shouldnt have any crqzy voltage spikes from that motor. But if you do unloaded test slowly ramp up the throttle

Ok thanks, will definitely keep that mind
Siiick dude sounds fun. What were all the theoretical numbers again, torque, top speed, and whatnot?

I guess I should add that “if you’re not pushing the esc upper limits of ERPM” you probably won’t blow up your esc.
@yoyotinker mentioned low kv motors so I think he’d be ok, but I could always be wrong. Time to “mess around and uncover information”

Torque is around 1350N (total Fmax) with a top speed of 65mph at full charge (~4.1v/cell)
