Cheap "high voltage" esc Quest

[snellemin]

I think I found for an affordable "high voltage" programmable ESC. I got it yesterday and it worked great with 3s1p A123. When I doubled the voltage it blew the stock tiny caps. Brought it to work today and added some better caps. I benchtested it with 6s1p A123 and it worked great. I'll use it on Sunday and see what kind of abuse it can take during dragracing.

I allmost bought this but no information abot this ESC hold me back, i think that its overrated and not so good quality. Blown Caps shows that. Can you tell something about fets?
But tell us how its perform? Trigger reaction? Lets say is it possible to correct car fly trajectory from jump with throttle without delays? Its realy imprtant becouse i race only dont do speedruns. And also tell about BRAKS are they good? strong and smooth?

I think I already have that same combo coming to me as well. I know the ESC is on the way, I don't remember if I got the motor too.

..... I actually bought this last week for one of my boats. I'm going to run 2s and 3s on a 24" cat that I have, but now I may have to drop it in a truck first.

snellemin,
I'm not too surprised you blew the stock caps on 6s a123's. I read your write up on rcu, and know your were pushing the limits. Hey, would you be willing to set up my esc with some 35a caps like yours? If so, send me a pm.

[snellemin]

That is the ESC man, which got more expensive. I used 4.5" wide thick heatshrink and soldered on 3x 330uF 35Volt caps.

To enable the ESC, you have to put in it reverse after the first beep. You'll hear another beep, which tell you that the ESC is enabled.

What were the ratings on the stock caps that came with it?

Hmmmm.........looks interesting.

I also had some problems with mine. I think you have to set your end points. Sometimes mine worked and sometimes it didn't.

end point on my remote? What should they be set at?Do you plug the battery in on full throttle and then go to reverse. I just get the two beeps.

I made a mistake. What I did sometimes is a calibration of the controller. I only played with it for 1 day and I had the beeps like you. So I played with it some more and I held full throttle, plugged the pack and then I went full brake and then neutral. I haven't played with it much as I plan on switching the brain board with another controller.
