Spektrum AR636 Receiver Initial Power-UP!


Guys,

I believe I found an Ugly side effect of how the Spektrum AR636 initially powers UP and how it moves the control surfaces. I am certain that this is why my Elevator is acting UP in-flight and WHY the servo ( I am certain it's the Elevator) servo at times makes this loud jamming noise right after AR636 initial Power-UP !

The following Video is my E-Flite AT-6 Texan with the stock Spektrum AR636 and I have been hearing and observing a loud jamming sound from my servos due to the manner in which the AR636 initially powers UP. This is very hard on the servos! That day I flew my AT-6 Texan twice with the new GEN ACES 3-Cell, 2600mAH, 45C Discharge Lithium Batteries and it flew great but, I am still anticipating UP Elevator during turns and other maneuvers, otherwise the model tends to nose down.

Just to be complete, I followed the instructions carefully and TURNED-OFF the help of the AS3X features but, after my AT-6 Texan lands and I hold it, I can hear the Ailerons still moving very slightly! I don't need any help!

The Jamming (at times) is very ALARMING at best because it sounds like the servo is Jamming up on initial Power-UP and Initiation of the Spektrum AR636.

My beloved AT-6 will now be a hanger queen until I will install that spare AR8000 with Satellite receiver.

I have posted the section of manual for the AT-6 Texan so, you all can see that it states:

Once the AS3X system is active, control surfaces may move rapidly. This is normal. AS3X remains active until the battery is disconnected


Okay, here's my Video where you may or may NOT hear the very violent movement of servos during initial Power-UP of the AR636!
