Unplug the fan and now, NO REVERSE!!
 

After complete rebuilt, My mmmv3 don't seem to want to engage reverse?
Nothing happen.
I unplug the broken fan. And now, No reverse at all.
Tryed to reprogram, Nothing.
Someone know want it is.
I hope I don't have to send it to Castle!!!

sure reverse isn`t disabled?

Yes, when I try to setup with the recever, mmm keep beeping when I apply reverse.
I connected it to castlelinkand everything seem to be ok.
I have a Futaba 3pm

whats your brake endpoint.

100%

Re-calibrate to the radio?

Yes and when I apply reverse it keep beeping!! Can't finish

Throtle set to normal or reverse?

Reverse

Oh duh, sorry. You already tried that.... Would it be a pain to reset the settings on the radio?

I know I had to reset my maximums for throttle (both forward and reverse) before I could calibrate radio to ESC. Course I dont have a Futaba either. Then it would calibrate and I could make radio adjustments after that.

do u have abs turned on?

Reset everything to default and try again. Did you just uplod new firm ware?

When I plug everything ( without toutching castle link) No Reverse. ( it was correct before that.
Nobodie toutch the trasmitter.
Tryed to upload newer version ( 1.22 Beta) then nothing.
Tryed to reload 1.21 but nothing again.
By nothing, I mean I can't calibrate the Break ( reverse) to the ESC. It keep beeping when I apply full breaking
Everything was working good before I take it apart:grrrrrr::cry:

That's exactly what happens when my throttle channel isn't reversed on my 3PM... but you've already tried that...sorry I can't offer help.
