Jeti SPIN of another kind

[lutach]

This is just too frustrating. I had 3 Jeti SPIN 200 that I was willing to send to Jeti if only they could have a car software added to them, but no so I sold my SPIN 200s. I already proved that a car software can be added to an aircraft ESC and if anyone says otherwise, well that's just BS if you ask me. There's a market for HV car ESCs and it's just too bad that these so called ESC manufactures can't make them. Maybe I just taking it too far, but it's just frustrating having 3 SPIN 200 and Jeti could even make them available for us car guys. Enjoy the pics.

IMO, it's not "just" software. Car and air ESCs have to deal with different driving characteristics where current peaks are much higher in cars. Well, maybe not compared to helis, but definitely most plane ESCs. Car ESCs need more copper for less I^2*R losses at high burst currents, not to mention the FETs chosen have to be able to handle both the high current peaks and whatever constant currents. And, car ESCs have to be able the extra voltage (above battery voltage) that could be generated during hard braking.

That said, I think it would be easier to add aircraft software to a car ESC than the other way around due to hardware design. Of course, if all ESCs were designed with worst-case scenarios in mind, application wouldn't matter since all bases would be covered. But then cost would be higher and/or physical size would increase and people would complain.

I've done it, so why can't a real ESC manufacturer do it. The SPIN 200/300 has plenty of copper to handle the large scale airplane they were meant to power and the layout of the ESCs are very similar to the old Schulze 40.160 and they even use the same MOSFET (Not sure about the new ones). They could've at least given it a try.

See "FighterCat"..

On another note, that's an awful lot of dang wires coming out of that thing!

I'll wait until they have their car ESCs working good.

To handle the AMPs, you will need them .

Man, that is one serious ESC.
