Re: Tech help needed
It really is what makes this hobby fun is diggin into it!! Don't get discourged, this hobby is not like buying a new car and expecting everything to work perfectly right off the bat, especially with the Chinese stuff. I would be inclined to believe that you have a twenty dollar or thirty dollar ESC thats out.. Have you tried to contact the seller and explain your situation?

Re: Tech help needed
That's exactly what it's doing Reg, I'm dumbfounded. I'm trying to work with the seller who lives in Korea, so there's a bit of a language barrier. They say it was properly tested and has no issues. I beg to differ. Hopefully they will take it back and fix it up. I noticed the hydros were pretty spongy and air bound. Could it have some type of safety switch that disables the pump or something?

Re: Tech help needed
I had some pump esc problems with my bucket loader. If the power was disconnected, the esc may just need to be reprogrammed. See if you can find the esc setup online, and follow the instructions. After I found the instructions for my esc, it has worked great. Good luck.

If the esc/pump is brushless (3 wires) then testing is much harder unless you have a spare motor you can plug in for testing. I have the A9 its a nice radio, go to the monitor window and check that the pump trim is set to dead centre (i would assume) so that the esc can arm Last edited by pyrosrock; 12-31-2014 at 05:15 PM.

Re: Tech help needed
Thanks Steve, it is a brushless motor. I checked all the trims on the radio and they were all set to neutral. It's kind of a funky design, there's a battle switch to turn the pump on, but when it worked it would also turn on apon pressing a stick on the controller, so the pump isn't running all the time. With the battle switch on, it would run all the time. I'd like to check the voltage coming out of the pump esc, but you mentioned it's difficult? I'm pretty handy with a voltmeter, what are the steps involved?

Re: Tech help needed
Make sure you turn the radio on before the model... It may be that the failsafes are triggering, and the esc's are defaulting to the failsafe rather than zero point.
Cheers, Ap |
