IMPORTANT! Startup power was bugged in previous versions of BlueJay up to 20.0 so the recommended min and max startup power for 21.0 or later has changed. See here for the detailed information: github.com/bird-sanctuary/bluejay/wiki/Setup The recommendation for version 21.0 of BlueJay is to gradually increase Min Startup Power (Boost) until your motors reliably start. Then set max startup power 20 points above this.

Hi mr.Chris . i have a question about BLHeli32 . i use 3 Fly Mode rather than acro mode on my 5 inch quad. On that case, i must increase Motor RampUp up to 100% so the motor can rotate on Low Throtle otherwise it will desync. And like you said, it make the motors got more heat . Do i have any option to make the motor rotate on low throttle ? i like to sent you the bench video,if you have discord or instagram.

I flashed v21, and after some testing I only slightly upped my min power to 1050, and set the timing to 15 degrees. I noticed a distinct extra crispness to the handling; not really big, but noticeable enough to make me happy about it. My tune was already pretty tickety-boo as it was. I kept to 48k, tho'. My throttle curve is already at 1.00 for both midpoint and expo in BF, with a custom curve for the throttle in EdgeTX. That setup doesn't like 96k at all. It needs a re-profiled curve on the radio, something I'll get to later. In the meantime, the few adjustments that I have made following your advice are working as promised. Small steps over time add up to big change. Thanks for the accurate info that lets me achieve that.

Great video, Chris! One comment: AFAIK you should not set the power rating to 1S. I'm pretty sure there's still a bug in bluejay that can randomly trigger the overheating protection of the ESC if the power rating is on 1S. And that can be pretty catastrophic if you happen to fly over water when this happens, as I had to learn the hard way.

Hi @ChrisRosser can you also look into whether the timing and pwm freq recommendations are the same for different motor kV? We have a huge variety of motor kV available, from 16000kv to 40000kv. Also, is it affected by esc deadtime? This is also wildly variant (5-70ms)

Chris, please correct my memory about torque, thrust and pwm. I remember that if we increase the pwm value like to 48 or 96Khz, the motors become smoother but it loses the torque. So if we lose torque, that means thrust is jeopardized meaning, it's affected. That means, torque and thrust aren't proportional.
@borisgubanov7558
Ай бұрын
You missed one thing: hover throttle. At 48kHz, my hover throttle is about 38%. Then I can use expo to make the range around 38% smoother. At 96kHz my hover throttle is over 50%. And there is no way I can make the hover throttle smaller and still be smoother. That's why I'm still staying at 48kHz

What about disc unloading while flight? Also you top up the voltage to 4V per cell on a thrust stand. When you consider voltage sag and disc unlaoding, Im sure the whole results of what is best also shifts over to the next parameter. Personally I leave all on 48khz and 22.5 degrees motor timing. Tried others, but this just felt best in flight. We need a wind tunnel thrust stand wothout toping up the voltage. I test all my favourite prop combinations with gps top speeds, acceleration and general flight time efficiency. Of course not on tinywhoops. Usually I take a props with a little more pitch than the recommended ones from the best thrust stand results. Disc unloading in the moving air and voltage sag just changed everything.

I see, this settings name is a bit misleading, you probably know this already, but leaving this for other readers with similar problem. it's actually the min power that each prop will spin, so a higher setting may lift it up the ground a bit, while 100 would make it ineffective since there won't be any flipping force. I tried 20, 50 and 75, and 75 worked really well for a hard floor surface. Thank you, problem solved!
