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!

Can anyone confirm or explain the difference between this ESC and the Mystery 40A if there is one as the Mystery is more expensive.

Can anybody tell me if this will slide inside a 25mm internal diameter tube? being 23mm x 7mm it looks close..

Did you check the radio settings, (mixes and end points) and calibrate the ESCs from the tab in the software. Check this video, the second part may www.link

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.
