Help!

ESCs will not arm using DX7 or my 9C TM8


My original project includes a GWS IPS-S2 (GW/IPS-DX2BB-2XCS), a CC Pixie 7P wired to an AR6400L.

The system binds, works the servos, but will not arm the ESC. It just blinks on and off so, I thought my wiring to the AR6400L was weak.
Made a new plug wiring, rechecked all my radio settings ie throttle NOR vs REV as well as the arming procedure low 1.5 seconds - move to WOT back to low......
Regardless ESC only blinks with NO beeps. Therefore still would not arm nor will it go into setup mode per steps.

So, I thought I had a bad Pixie 7P, swapped with an ElectriFly C-12 connected to the AR6400L.... No go, same problem.

So, I then bench tested the Pixie 7P using an AR500 and it would bind, control servos, but would just blink as well.

I tested both the Pixie 7P and ElectriFly C-12 using a new AR6400L and an AR500 and both ESCs just blink...... happened with both my Transmitters!

I guess it's not the AR6400L

I can not find the problem, it does it with both my DX7 and my Spektrum converted Futaba 9C with the Spektrum TM8 module.....

It's the lower throttle endpoint that you need. It's at 100% now. Try lowering it towards 150% and you'll hear the bleep as the ESC arms.

I did try the 150+- on the DX7 and 120 +- on the Futaba 9C Spektrum so, I'm going to create "new" models and start over again.......

It's driving me nuts!!!!

The beep sounds that you normally hear come from the motor. So, either you have two faulty ESC's, or...

The motor (or its connector/wiring) is faulty.

...CC Pixie 7P...
This ESC may have a "Safe "Power On" feature". Does your ESC require/use an arming sequence (series of throttle-stick movements to activate the throttle-control)?

Yes it's low, plug in battery leave in low "off" position at least 1.5 sec, then WOT "up", then back to low..... ElectricFly is the same to arm.

I've had esc's with a DX7 and have had to set my throttle to medium before plugging in esc. Then full power and then all the way down for it to arm.
