I have these escs on an old ZMR250 which I just put a new BetaFlight FC on. The site says oneshot 125 compatible but do I need to do anything like flash software to the to use it?

Thanks, Matt

You should be able to select the ESC protocol in the configuration tab of BetaFlight.

They should support OneShot125 without needing any firmware updates. I notice on the RTFQ page that they are supposed to be BLHeli compatible, but I don't see these ESCs in the BLHeli supported Atmel ESCs document.

You would probably be better off replacing them with some nice BLHeli_S ESCs. If you really want to take advantage of the Betaflight F3 flight controller, you need to be able to run Multishot or DShot. If the fastest ESC protocol you have is OneShot125, then you can't have your loop time any faster than 3.8KHz, so you'll be missing out on 4KHz or 8KHz loop times.

He could use fast looptime with slower unsynced esc pwm speed.

I was trying to be brief as I tend to get long winded.
I initially tried flying this with pwm and I had to lower the p gain so much to get rid of the wobbles, that I knew it should do better. My first thought was switch it to oneshot125 so I connected to BetaFlight and clicked on oneshot125 and saved. I can't get the motors to run after making this change so I figured they needed flashed. I tried connecting via BLheli configurator. It acts like it's working but then gives me a failed error. I tried resetting the endpoints of the escs but still no luck.
I was just using this ZMR250 as a testbed for the BetaFlight FC. The frame and motors aren't worth the expense of new ESCs.

Thanks, Matt

The ESCs you linked have SimonK boot loader (and maybe SimonK firmware), so I don't think BLHeli Configurator is going to work. I'm not familiar with SimonK details, but you might try digging into it from that angle.  (The site mentions flashing with USB linker/afro linker/Nano linker tools.)

I've never heard of any of those things. May just try more pid tuning and leave it on pwm.
