4PCS 35A ESC Lipo BLHeli_S Electronic Speed Controller Support Dshot 150/300 / 600 Brushless ESC for FPV Racing Drone Multicopter Quadcopter

I used these with a 4S battery, and they work just fine. No issues so far.

Stay away. Catches on fire reliably.I'm an experienced FPV flyer (>500 in flight hours.) Bought a pack of 4 for a 5" quad. On the first day of flights with these, two caught on fire. (Replaced one in the field.) I am a competent builder entering the hobby in 2016, and this has never occurred on literally dozens of other 5" builds. I suspect this product incorporates MOSFETs that aren't rated to the amps needed. The result is a fire.Be very careful, if it happened twice, it's clearly a design issue.

I use these ESCs to drive the weapon in my 1lb combat robot, and so far, I haven't had any weapon issues that I can trace back to these ESCs, and they can handle the current I feed them, so I like them!

I was skeptical on what to expect for this price. Well 20 or so flights later I can say these lived up to their specs and frankly are decent. Bought these to replace a set of ESCs of an Eachine x220 whose vdry literally caught fire after a crash. Not only these at least seem to have overload protection, but I think motors run slightly quiet and cold than before.

They worked fine at first. Not even 5 flights and 2 of the 4 esc's blew. When they worked, they worked fine. Plugged in a battery and it just burst into flames after some smoke. Maybe I was just the unlucky one or these aren't good quality. Not sure.

I been flying 2 drones with these and have at least a hundred 4s battery packs run through them without so much as a hiccup. Reflashed with bluejay firmware so have rpm telemetry to take advantage of rpm filtering. Easy peasy to solder. I wiil keep buying them.

I used these ESC's inside a flite test airplane. I ran 4s to do all my tests and checkouts. Everything worked. Then I moved to the 6s batteries I was going to run and then the fire started. Almost burnt my whole plane... great smell!Be careful running these with 6s. Maybe they are great for 4s but I will not take the risk again. Not using these.

I may have got one defective out of the 4 that was causing the problem, but my quad flew smoothly on 30a little bee escs, but when i tried 6s one failed immediately, so i hot these and right away i took off and knew something was wrong. At between 10-40% throttle it starts jerking uncontrollably. They are very powerful and i did endurance tests and nothing failed, just can't fly with that jerking, i tried adjusting all the settings and checked all the othe equipment, swapped tc to other qwad and its fine, these esc are no good
