I go over all the different things that killed your ESC (Speed Controller) and things you an do to prevent them from dying.

Thanks Preston!
I have a full new build that makes my motors (F60 Pro v3 1750kv) hot no matter what filters or tuning I try. I swapped everything but the new ESC (HolyBro Tekko32 F3 Metal 4in1). I just realized that’s the only component I haven’t swapped out. I assumed b/c is new and cleanly soldered that it couldn’t be the cause. Might the ESC be the cause of the hot motors???
Thank you so much for this video.. Much instructive..much respect.. FL1 for life!!!
Great video! Maybe people will finally stop making fun of me for soft mounting my esc now 🙂
Sweet video! Learned a lot!
The thing i dont get, is that I had no problems with single escs. Going to 4in1 escs last season ive gone through like 7x 4in1s and like 5-6 motors?! Escs Tmotor/aikon ak32/hw 40a/hglrc 428. Motors – tmotor f80 2500kv tmotor pro2 2500kv and avenger 1507 4100kv. The wierd part is that i havent crashed hard. Rather dented gates. When a motor has toasted it has been a different motor eash time. 3x quad setups.
I always conformal coat my ESC’S before I solder them up. Accidents happen and occasionally a soder ball flies off. It’s way easier to pick out and it doesn’t cause any damage if it’s coated :p
Preston – 95% of ESC failures I’ve trouble checked for other people have been caused by the BLHeli 32 setting “Low RPM protect” being set to off. They have this setting turned off – have a prop strike – and the ESC is toast.
The biggest shit i ever heard…. never burned an esc with betafllght. Do your job right and we don’t have burned esc’s. The is only a fl1 thing dude.
Apparently I’m a unicorn, because my most reliable setups are $7 motors, cheap BLHeli_S ESCs, and I’m running 6S mid-KV (2000-2250) and I haven’t had much in the way of issues.
The stack mounting advice is solid, that absolutely helps. I probably will add the common ground strap all the way across the stack to see if that helps.
False advertising on box directions in my case so…but good info on my way
Awesome video Preston. I was thinking the ground pin could be In The center of the connector and have it 0.5Mm longer or how ever much longer the tolerances on the connector would allow. Also no mention on doa esc and what could of potentially gone wrong in QC or shipping ?
Great video man thanks for the content!
Bring on Falcox please …..
I would think this video was in response to something I have seen, A high failure rate with the Flight1 ESC’s that say they can do 6S but really can’t handle a high discharge rated battery. try using a lower discharge rate like under 75C more like 60C at 6S the voltage is what is important. With 32bit mcu’s to much current in to short of a time frame will take out your FETs and melt traces. the lower discharge rated battery will limit the current and control a high speed MCU protecting the FETs and even cheap motors. And there is really no ground in a delta motor config there are 3 coils that the ESC’s sets up AC electrical fields that are out of phase in one direction and the magnet structure in the bell of the motor follows that offset phase around the stator, I have seen bolt32’s just turn in to a fireball with a 6S 90C or 100C battery behind them in the air so that wasn’t a bent pin. It’s just the 32bit MCU trying to switch the FETs to fast with more current available than the ESC’s can deal with, cheap motors or pricy one’s it does not matter. But Nice motors are a lot more fun !!! ESCs losing switching control of the MosFETs is what normal smokes motors and then the smoked motor compleats all the fun by killing the ESC.
Build some current control into the ESC’s , Firmware current limiting is just to slow to protect FETs switching so fast !!!
