Currently:
40" double kick deck (Shorty later)
10s3p 25r with charge only bms
Focbox
6374 170kv sensored from es8 .de (10mm shaft)
Marcmt mount with idlers
Caliber 44°
1/4" risers
15/36 15mm belt
Was 97mm abec 11, not enough torque
Now 83mm…meh.
Gt2b mad monkey complete
I’m a little underwhelmed with the performance.
I know I don’t have a lot to go on, but I do know it’s slow.
**Slow to accelerate, and lacking torque for even small short hills.
As is, it seems it’s not going to work well for its intended purpose, the lunch runner…i.e. Leave my truck at the job site, go find food, eat and return in 30-40 min.
It’s usually only around 2-3 miles or so to wherever sounds good.
I was hoping (on the 97 abec’)…for around 25mph/40km cruise speed with 28-30 mph top.
The basic calculator says 25mph max speed unweighted on 83mm, and it feels like it might do that on a full charge.
Issues:
The mount, motor, belt and 36t pulley are way too close to the ground on 83mm wheels and will no doubt scrape often.
I really want to use the 97’s that I have, but could buy some 90mm wheels I guess.
Smallest motor pulley I can find is a 14t pulley with 10mm bore from beltingonlinedotcom
Direction, I need some.
Any positive experiences with single drives in regards to bunny hills, i.e. 8-10% or 5-6°?
In other news,
I’ve got 107’s and a Hummie’s maplecarbonbamboo deck, and need to start collecting parts for it as well.
Well, my FocBox popped and the magic smoke came out.
Idk what happened. Using vesc tool. Sean, @squishy654 was setting it up. Going through motor detection when it happened I think. I don’t really know more than that.
Sean had a spare vesc in a drawer but didn’t have the correct bullets to hook it up to the original motor, so he hooked me up with a 125kv motor and set it up on foc.
And up and running. It was unbelievably quick on 83’s and even on 97’s it gets it. I’m at 210# and it pushes me up the hills well, even accelerating up the mild ones.
Calc says 20mph, plenty fast for now. Depending on how It gets on with longer hills, I may go to a 18t (25mph top)
Still haven’t got a valid enclosure. I need to make one.
I tried, but not hard enough
Looks like a fet burned… Make me think his old motor was shorted… Have you checked the resistance between phases of the old motor to verify if it’s shorted or not?
It appeared to me like something metallic had fallen in the holes near the phase wires and shorted out between 2 connectors on a fet. It powered up just fine but when we went to do the wizard and the tests it immediately smoked
Thanks for the offer @barajabali …I’ll get it in the post if you’re still game.
Board is working well, have made 3 lunch runs so far, and a few cruises around town.
Had a get-off a few min ago…at full throttle, heading to lunch. the power cut off with no warning. Idk what it was, but it’s happened a few times.
I think I just gave up and jumped off, honestly, as tame as it is, I should be able to stay on it with a chopped throttle, gonna try and practice that.
The PG&E guys saw it and were impressed that I ran it out.
It was many quick steps and I scrubbed enough speed to fall safely, not a scratch…
