Does anyone know at which voltage this is 40A rated? Because 40A x 22.2V = 888W BUT 7.4V x 40A = 296W This is a huge difference!

its about with your motor and to lift how much weight motor usualy works with Lipo cells: 4-6s thats why that is difference i hope i answered ur question

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.
