Wow...... I have been flying my CX2 for quite a few months with little or no real issues. It has always been my one source of garunteed flight until the other nite. I lifted off and the heli flew up and slightly backwards and about got me in the nose. (Before ya ask...... I do have a fairly good sized honker!)
Checking it out I noticed the ELE servo wasn't responding to TX inputs. So, I did my normal trubble shooting teckneeks and positively identified the servo itself as the problem. Last nite after getting up from my nap I decided to go ahead and check it one more time before changing out to the new S60 I bought at the LHS. Weird enough......it responded fine and I actually flew it for about 5 minutes in the kitchen. Piros and short runs up and down the length of the kitchen were no problem and never once did I ever notice any ELE loss of control.
This morning I decided to snap out a quick flight around the front room and antagonize the fish. Dead servo again. I will go ahead and change it out but I am wondering if perhaps my 4 in 1 has begun a slow descent into the purgatory known as dying electronics.
Servos are not designed to last forever but I am sure it is less than a year old and has maybe 25 hrs of flight time total on it. Anyone else finding the Eflite servos sub par in the S60 size? I know the S75's are not all that and a bag of chips but the S60's I thought had a good rep.
As long as i have owned this CX2 it has never been crashed with power on so I am pretty certain the 4 in 1 has little if any abuse to it. I was running a CSRC 7.4V 8C 800 mAh in it at the time and voltage was right at 8.24V charged with a Astro Blinky balancer to smooth out both cells. The battery is never charged above 1C or .80A.
Weird....but the luck of the draw I suppose.

what tx? - you might make sure its the servo but swapping the elev and ale servo plugs and see if the problem moves - if it does iths the 4-in 1 and if it doesn't then its the servo (or the tx)

i hate intermittent problems - break something else so you have something proper to fix lol


edge

Its the stock TX edge..and i did switch servo leads in channel slots. The forward servo (aka AIL servo) responds in both ELE and AIL slots on the RX. Tis definately the servo and not the 4 in 1. I just found it odd that it crapped out without any glitching or fuss. One day it was fine.....the next it was shot. I will probably end up tearing it apart and see if theres any loose connections.
As far as the TX goes voltage is at 6.1V constant so I am pretty positive its the servo itself. TX glitches tend to build over time unless one has dropped the TX or gotten it wet. For all my other heli's and planes I use my DX6 and with the exception of one of my planks.....glitch free. That one i am convinced is a RX issue and will have to be sent in for repair. I am hoping that HH will honor the warranty on it and fix it for free.

How are the servo-gears? Or is the servo-motor just dead? It sounds like (i used to work with computers, so i compare most things with that ) it may have overheated. CPU/GPU/RAM all start behaving like this (on-off, good-bad, etc) if they've overheated too often even although most systems have thermalprotection nowadays. Good sign/signal that things are 'dying'. Luckily it didn't die suddenly while in mid-air!

Maybe pushed/pulled on/over it's maximum travel for too long? Or it had to apply too much force over too much time?

Yep, had the same problem with my CX2---After only a few flights---I replaced the servo (don't remember which one, now) & no more trouble!---I did disassemble the servo, removed the gears so as to disengage the pot, then plugged it back in & moved the stick, nothing---I then spun the motor spindle with my fingers & it started running---I ran it "Full" stick for a few seconds--- & then again---& then again---Reassembled it & it works normal---Still I don't trust it so I filed it in the "TC"---

Heh........ as I was removing the suspect servo I pulled 2 of the 3 wires right out of the connecter. Pretty well gives away the issue with that servo. I rarely pull on the wires themselves but this morning changing it I figured what the hey. New servo is installed and will solder up a new connecter to the old servo and keep it as a spare. Funny how it just quit like that, usually a intermittant (SP) glitch or 2 would be more normal than just not working.
Good point shufflez.....it most certainly could have decided to quit while in FFF and plow itself into the nearest obstacle. Had it quit with the swash tilted for FF....... It would have been one of those helpless blank stares followed by cursing and wincing as it impaled itself most likely in the hardest possible spot to reach it. Luck was on my side on this one!

there's still a big ole 2-channel toy heli stuck 50 feet up in the tree by the pasture from before i started real mini-heli's


edge

My cx-2 has the same problem. I suspect it was caused from the fact that the wires make a 90degree bend straight out of the connector, if you straighten the wire it works fine.

I had bad servo glitching on my newer CX2 until I re-routed the servo wires as far away from the motors as I could. No more glitching.
