Chieftain turret turn motor strange behaviour on initial switch on

Post by Mark Russell » Tue Jun 30, 2020 9:27 pm

Hi I have some strange behaviour with my turret turn motor only on initial start up. When I turn on the motion pack switch the turret turn motor either rotates slowly or quickly. If I turn it straight back off and on again all is ok. I assume that this shouldn’t be the case? Everything else works and performs as it should. Any ideas anyone? See link below...

Hi Mark

On the assumption your are using a modern radio setup, like the Spektrum, try going through the binding process again. First ensure all your controls are neutral, any trim, sub-trim or offsets are zeroed. When you bind to the receiver, the settings on your transmitter are you failsafe settings. When you initially switch on, until your radio binds, your receiver will be in failsafe. If your turret turn has any offset, it will operate until the radios bind.

Hi Mick thanks for the response. I have already tried this. All controls are centred, sub trims all zero etc with no offsets. I turn transmitter on first so there shouldn’t be an issue? Anyone else seen this issue as I have tried everything to no avail???

Hi Mark I had a similar problem with my Tiger 131 running a Seckrum DX8 on power up it would sit nicely wait then all of a sudden charge off across the garage smashing into the wall, after lots of painful work taking everything apart rebinding I noticed that the small block that carries the two small antenna had dropped off it Velcro as soon as I put it back in its correct alignment everything started behaving itself. Try checking the antenna alignments with your RC’s recommendations.

Which transmitter/receiver are you using ?

A quick test, and you'll need some space, or do it with the turret removed and just watch the motor ;-)

Turn the transmitter on and wait for it to fully boot.
Turn the tank on.
If it starts doing this, move the transmitter stick fully to the left and then to the right and back to centre.
The motion should stop.

Hi Adrian it’s a DX8 with an AR8010T receiver. I’ll try this tomorrow. Are you saying that if I do this then it will stop doing it permanently? The antennas are located at 90 degrees to each other. The interesting thing is that once turned on-off-on if you turn it off and back on within say 30 minutes then it’s ok. Leave it longer and you have to do the on-off-on...

No, unfortunately.

There has been a known issue with some Spektrum receivers and these speed controllers, due to them outputting pulses before they've actually connected to the transmitter. I don't know for sure if this receiver is one of them but the symptoms look similar.

Tried what you suggested Adrian and it makes no difference. The turret continues to turn until you turn if off again and straight back on...
Anyone else had this issue with???
Help...
