well guys, I’ve had exactly one full ride in march (Mar 26, 2022 - metr.at | 3CMiF). started with 30% charge and did over 50km. it was nice.
few days after I charged to full, and one of the HDs died when I pulled the trigger (Mar 29, 2022 - metr.at | Jqw3v). I just remember the feeling of falling to the right and the board going to the left under some cars. so the failed HD60 went to trampa, and I should receive it sometimes this week.
however, this is really heavy build. I suppose that I’ll ride it a couple of times this summer, and then sell it to somebody who has an elevator to get to his apparment
another update! got back from norway, tomorrow picking up the hd60 @Trampa sent me. hoping for some luck winding this together on a software level. last time was pain to calibrate. and, well, was also unable to run on 12S
I did new calibration. the new hd60 feels solid, however the old one has some issues. I tried swapping motors on this one (vesc ID 111 and 116), and it started returning correct data. what the heck… apart from the same results on 116. how is that possible?
I tried rolling in my room from one side to the other, and noticed that sometimes one motor has problems listening to go to reverse (running hyst) and takes fraction of a second to respond like the other three.
has anybody tried testing boards under load before real use? like on a threadmill or something. essentially duplicating a dyno for cars. I’d like to have more confidence before going in the streets
I’ve been thinking about a test rig for a while now. I will build one eventually. I think a treadmill with belt might be harder to make consistent than two rollers.
Solid build, I’m sure you can break some ankles with how heavy it is going 20 mph There are some nice off road hills where I live and just straight roads if you got the need for speed, I finished my first build a few months ago. For a budget of 400$, it runs pretty damn smooth. I skate in general so way before this I always went hillbombing, committing to a speed test on my build was no biggy. I got it up to 32mph. 0 speed wobbles from my Caliber III trucks with medium tightening on the bolt to solid balance its the fastest it can go (for now ) Do not sell something you worked on. Especially putting so much time into perfecting it, I’m sure you can find a solution for your living situation. Maybe start off slow and get used to how it performs. Then gradually just increase the speed, tame the beast before you hop on!
. You need some tank treads on this thing
