I love the Unity, but there is a fundamental problem in what you said, “some lemons” are not okay. There should not be a short straw drawing in whether your unity may or may not try to kill you. That is mostly the negativity behind it. Once you know your unity is a good one, you’re safe. The design is not bad and it is pretty durable, but it’s the initial week of whether “will my unity launch my ass into the ground” that is not cool.
And it is basically QC’s fault. the percentage of DOAs are not acceptable for an electronics component like that. DOAs should’ve been weeded out before they ship, and you absolutely cannot blame mis-handling in shipping for a component that needs to withstand the vibrations and abuse of a skateboard. The Unity suffered from bad assembly procedures, from cold solder joints to bad components out of the box.
Mine cut off and kicked back on throwing me off the board it would do it randomly. It wounded up being the Rx board after inspecting it. I was able to replicate the problem with the Rx board.
After going with a different more reliable controller I have had no problems.
Your entitled to your opinion and that’s fine.
I must be one of the lucky ones were mine works fine.
Sometimes you can get around the problem if you use a low battery current for the half of the Unity hooked up to the PPM receiver/transmitter since it puts less strain on the 3v/5v rail which comes from the DRV. But you shouldn’t be forced to use the same battery limits as a 2017 VESC after paying $3-400 and now that enertion disbanded you’re left with a paperweight if you get a lemon.
I’ve never had an issue at high speed but I have a friend who says it has happened. I have really enjoyed the Unity as my first (V)ESC. Brb gotta go ST-Link my Unity because I am an idiot.
To be fair. Unity has put my brown ass on the tarmac more than twice. That shit is traumatizing and that makes it hard to fully trust it after the facts.
But I still love it. All you need to do is treat her with respect. Ride like a total pussy and y’all be aight
The fact there is such a wide range of experience with the reliability of the unity is concerning in itself. I have 5 unities, 3 currently in service. I’ve pushed them to max power on occasions, and every fall I’ve had was completely on my part, they’ve been through crashes and rebuilds and they perform perfectly. But to be fair I have all of them running on UART so maybe the problems are all PPM related.
And of course. The little hiccups that @Kellag is always talking about.
I was also tagged as crazy when I told peep that motors don’t pull evenly under light loads at high speeds. Shit is no lie It’s a reality.
I’ve owned a shit ton of unities and they all have done the same thing
