These things wont work when flashed with simon k on NTM 25-30 1100kv. I flashed them with BLheli and they now work fine. the 50 amp ones dont flash either. now that i have them figured out i love them. they work quite well as they are pretty fast out of the box

Hi guys, i got problems with this ESC, they are not saving the calibration after exit the Calib. mode. When they are inside the Calib. Mode they take perfectly the calibration and the motors run great, but when exit the mode and arm the APM they just runs like nothing happend. (Not Calibrated) I allready calibrate the 6 ESC independently and all at once, with APM and without APM My question is: is the APM capable to create this problems or is something else?...i really dont want to flash the firm to Simonk. Thanks guys

5 thumbs up!
Wow, I am glad I bought this when I did! This is a fantastic speed control. I hooked it up to my new HK 450MT project and have had no problems. I haven't gotten the chance to really load it up yet, but it runs cool in hovering (test flights).

I deducted one star because it comes with no instructions. While you can build the HK 450 with T-Rex instructions, I wouldn't attempt programming the ESC with them!

Thanks again, HK!

Best ESC so far, will not use others for the time being. Very easy to program with the correct programming card.
