I have not tried this Arc200 but I have a general remark I want to make not directed at anyone in particular.
I see people all the time stating their settings.
Without a log to know how many amps you actually draw, settings mean absolutely nothing.
It is equivalent to saying I have setup my turbo car to operate at 2.0bar and 500bhp.
Unless you have actually used that, then we will never know if it can take it without the pistons going through the hood, will we?
Only downside is i heard its difficult to set up? Or do they now have a user friendly gui? And sizeā¦ But vesc6 isnāt small eitherā¦
No itās tough to setup. What I mean by that is the config process is very different from the VESC. FreeFly has a great youtube video that walks you through the setup process though.
Itās slimmer than a VESC 6 but longer, takes about about the same total space.
The FreeFly Arc200 has logging capability, Iām happy to get you some if your interested. I might have some on my home notebook, Iāll check tonight.
With that being said, I did log data when testing the Arc200ās and it is impressive. When I sayā¦
ā¦Iām not telling fish tails, I actually did it.
Yaāll should talk to Jake, @longhairedboyās kid. He has been trying to demolish some since Nov 2018 I think.
Iāve been using the esk8 1.2 controller from esk8.de and Imo they are a better focbox. Higher quality components, better price, actually ship when you order them.
Been running 12s FOC at 70 battery Amps without an issue.
Only issue is they are rarely available I was gonna link the website and it had 2 and stock so I had to buy them before I share the secret.
Ohh and it supposedly comes with a 2yr warranty 
Attila (owner) has done a good job about this.
Wrong topic.
I notice this a lot on my VESC 4.12 skate. Just a bit under top speed it feels like the nitrous kicks in.
Of course about 30 seconds later the ESC starts throttling because the FETs are too hotā¦
We would all have used RC based ESCs like the HW Max6 Iāve been using?
Nah. Iād have gone full retard and kept my ZombieSS FETzilla 36fet controller from back then and certainly come up with a deathly machine in the end. Many e-bike ESCs available since long, itās big but some are slim and pack a lot more power than what we have even now. Which is not really needed for e-boards, truthfullyā¦
VESC gave a big boost thanks to itās advanced feature (like a full fledged bike ESC) + high power + tiny form factor!!
I wasnāt being exhaustive with the number of options. Some use car ESCs with an AS5047 encoder quite successfully for finer control. Some of the fastest race esk8s today use Castle Creations Mamba XLX ESCs.
Interested in what motor you used to pull 120A?
Sure but itās all about practical factor too, if you compare our ESC to bigger ones, we were just late to the party when it comes to things like FOC for example.
Thatās what I meant.
I just noticed this yesterday with my Maker-X 4.2ā¦ it had one hell of a sudden burst of torque at the top end compared to my 6.6.
Now I understand what my relatively newbie friend was complaining about as he rode along with me. 
A heatsink goes a long way towards eliminating this problem. Of course when you solve the vesc overheating you are left with overheating motors and not much can be done about them
The VESC 4.12 design uses the FETs that are not conducive to adding heatsinks, unfortunately. (They put the heat into the PCB itself) Really just need to change the ESC next time Iām in there, but this skate is so reliable that I havenāt been in there for a long time. Really if the ESC doesnāt die, then it will probably stay as-is. No reason for me to crack open a skate that hasnāt broken. If it aināt broke, donāt fix it 
If I conformal coat my Focboxes, can I just use PC thermal paste between it and my heatsink?
Woops wrong thread lel
I have a 1/2" alumimium plate to which the vescs are bolted on.
My Focboxes used to thermal throttle constantly, after using the heat sink they never got over 80C
Yes but the problem is thatās a 4.12 not a FOCBOX. I also love the OG FOCBOX
