right here we go,been doing some research into these esc's why they are so unreliable
This is a piece iv copied and pasted with permission from a guy who has experience with these esc.
This goes for TFL,SUPPO,HK,MYSTERY ESC
The main cause of failure on these devices is heat, followed by improper assembly. The capacitors on the board are inadequate and can quickly fail if allowed to spark charge on higher voltage setups.
Install an additional capacitor to help maintain voltage under a load. The capacitors on the board are inadequate and will allow the voltage to drop quickly under load. This will cause more heat in the FET's and eventually lead to overheat, failure or even fire.
Install an no-spark resistor. This will allow the capacitors to fill more slowly, helping to prevent premature failure from "spark charging" which causes excessive heat and failure.
DO NOT OVER STRESS THIS ESC
Mart this has come from a reliable scource and has even had these caught fire,he also recomends only 50-75% of total amperage the esc is rated for on 6s,but recomends 4s for longer life of the ESC
He also recomends a 100Ohm no spark resister and a rubycon 4700uf,105* capacitor fitted directly to the the to the esc on the pcb
Reheat shrink when done and use a non acidic sealant to seal the ends to waterproof the esc.
Only giving this help to or any1 else who buys this product and dont want to read youve had a fire or nout thats all
