T-Motor F55A Pro II 55A 3-6s BLHeli32 4-in-1 ESC w/BEC

Things been tough so far :)

Incredible powerful and fast signaling. Super durable so far. Many others also feel the same. T motor makes a great product. Very good looking heat sinks also

Best 4in1 money can buy, a bonifide tank built to blow your quads motors right off the arms.

Worked fine until I used a 6s lipo -some smoke came out and motor 2 was shorting out, but it was the esc causing the issue. Im going to try and return it. I had good luck with the non f3 version just say -n

The Pro I line of this exact ESC was a complete piece of trash, I bought five of them from GetFPV and three of them failed immediately. They are not rated for 6S, I literally smoked a brand new 2750kv TOA motor - as in, sparks and smoke and my Chameleon falling like a rock two feet in front of me - both ESCs died in the same fashion, dead #2 ESC in both after just a few flights each. Then the third ESC the circuit board backing fell off, no adhesive with the companion daughterboard and it heated up to the point of melting the solder joints that were holding it on.So then T-Motor pulls then entire Pro I line during all of this, I processed an RMA with GetFPV and agreed to hang on to them so swap them out for the Pro II line. Later after the Pro II line is released, T-Motor wouldn't honor any replacement citing to warranty even though I had documented via GetFPV RMA all three failed ESCs within a month after purchasing them.Nonexistent company support, badly engineered product, use something else.
