Brushed Power System Throttle Reverse
 
This one has me stumped....not hard for that to happen these days....lol

Any thoughts are welcome.......(well almost any)......lol

The TX/RX is an older 2.4ghz (4ch/TX - 6ch/RX)....FMS/ArtTech/BlitZWorks.

The motor is the standard GWS Slow Stick (geared) brushed.
The ESC is a Turnigy Eagle 30amp.
The battery is a 2s, 7.4v, 1600mah.

Everything was in good working order the last time I powered everything up (on a Slow Stick)....been about 8 months ago. Batteries are fine, use them occasionally on the Tiger Moth.

Got back from flying this morning and a buddy was bugging me to bring out the SS again so we can play tag.....lol

So, I dusted everything off and put everything back together.......did a bench test on controls and the motor would not turn over.....no beeps on the ESC and control surface's worked fine.

Powered down everything, check'd reverse tabs.....all ok for this application.....power'd it up again, no ESC beeps, throttle stick down, but motor now running full throttle......Powered down, reversed ch2 (throttle), powered up....same thing, motor running full throttle.....throttle down by pushing stick UP.....lol

Tried three re-binds with throttle stick in 3 different positions......no change and ESC beeps as if it senses the throttle stick NOT in lowest postion (down)....no other beeps and motor turns in proper direction when running (checked it with a prop attached to make sure).

Tried one more boot-up....with throttle stick down, all tabs correctly set and no prop.....same story, ESC has that slow beep...beep....beep like stick not in proper position...and motor blazing (it will stop and slow down as the stick is shoved upward).

Never had this happen before with any application I've built with the brushed slow stick (reversed motor once due to wire crossing)......and yes, I've checked red to red....black to black and plug input to RX....all are as I have done previously...100 times....lol

Really don't want to put the Stick on the DX6i and waste a good RX and selection slot.....but may have to if the cheepy TX/RX has given up the ghost.....it's been pretty good to me for the Stick up until now.....lol

Thanks in advance........:oops:

I've had this happen before and reversing the throttle channel has always fixed it. my guess is the throttle channel isn't actually reversing.

Normally reversing channel works....so I just tried a random test....reversed each channel sperately and powered up 4 seperate times...nothing changed...then set all channels reverse and powered up, now the throttle is correct.....needed to fiqure out what each one was (order) since they do not follow the TX/RX manual order anymore....lol

Have now tested it with new settings 5 times.......seems to be ok. Acted like it was some kind of glitch....even after I re-checked all the wiring for loose connnections (shorts) and re-binded a dozen times... hate not knowing what the actual problem was(is). I'll know once I get her back into the air, at least it's only a Slow Stick.......I'd never take this chance with ANY of my other craft.....::o

Thanks.
