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.

I've been running these for several years, probably a dozen now in planes 20A on up to 40 A, never a failure. They're identical to Mystery, just a relabel.is all.

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

They measured wrong. The heatsink is 23 but the board itself is 25.5 including heatshrink.

Every motor I've tried with this ESC runs VERY hot. Also my battery time is shorter. You can to better in this price range.

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.
