Solid esc

Bought this for a build I'm working on. Been flying one on my ledrib skyliner with absolutely no issues.

F55 PRO II 32Bit 55A 3-6S 30x30 4in1 ESC Solder-Free

I had to purchase a replacement ESC after five flights with my Skyliner MK3. So I don't have faith in the sturdiness and reliability of these units. Thankfully, the replacement process was simple and easy. I hope this unit will prove to be more reliable.

Christopher Reiner
Great ESC

Installed in seconds, was flying immediately after...shipped crazy fast too. Highly recommended!

Easy to install and get back to flying

I’ve put these escs through some serious abuse! I went with the solder free since I already have solder free motors so I was able to change it out and get back in the air nice and quick
