Watch when u acquire the Axe as with mine the Bluetooth doesnt work from day 1. But drag for me is reasonable for my own use. If u wanna strong drag nothing beats Hh brxl w/crawlmaster pro but all brushed tho! Which I do not mine! Again my opinion, after trying a few brushless I can get my hands on like roc412 both 1800kv+500kv powered by rx8 puller pro 2700kv powered by mamba x, hw axe 2300kv system, I found out I m a brushed person!

New hobbywing axe firmware clearly states must be connected to axe 540 motor, I'm thinking it must be a typo because it just about set my house on fire. The new 01-00.2.01 Might be only for the 550 motors unless I'm just unlucky. Basically as soon as i update to the new firmware the 540 motor only tries to spin but doesn't instead of rotational force I get thermal energy which in certain situation might be great but right now not what I was looking for. Let me know if you had different results. as you can see, it clearly says it should work on a 540 motor.

OK so maybe I found out why it did this, for some f***ing hilarious reason HW decided to cut off the instructions about "AUTOMATIC" motor pairing....

and by AUTOMATIC they mean you have to do it manually...
OR else your s**t might burn up.
Yea im pissed, who knows how much life just got removed from my motor because of this.
And by read below HW meand google for more info we didn't link to on this page...
On a completely different web page I found more information....

I mean seriously If it's going to destroy your product maybe disable the motor until its been done?
Or at least make a popup for when you update the firmware.

If it wasn't for the smell of melting hot glue that holds the receiver an inch away from the motor I probably wouldn't have caught it before s**t got real.

So after the "Automatic motor pairing" the motor works again, seems like the motor surges or pulsates at around 15% throttle, I don't remember it doing that before. It might be because of the 30% overdrive. Ability to select the throttle matching mode is kinda nice.

Welcome to the downside of FOC controllers. The potential for going wrong is far far higher than trap controllers.


Since I'm literally the only person that complained about the velocity loop, sounds like this update is just for me!

Don't know what a velociraptor loop is but it sounds bad, the motor vibrated, for a second I thought my drive train was bound up but nope apparently there's velociraptors involved then?
I tried pushing the car to move and help it along that's when I smelled the velociraptor whatsies trying to set my stuff on fire.

You can't like this so don't even try...
The bad thing about typing is its written right there, obviously I didn't mishear you but if we were talking in person, I totally would have misheard you and this stuff would be funnier... especially because IRL I sound drunk all the time because I had hearing problems, well always... but more so as a kiddo.

So this is how a velocity loop shows itself? I was expecting something faster like a runaway diesel engine.

This is how a mistuned velocity loop shows itself. It jumps around the intended RPM but can't lock on. Its the same as tuning the PID on a quad, except that HW didn't give us the ability to tune the PID.
