Found this on the Futaba website. It refers to non digital servos, but may explain the problem.

I have a similar problem on CH2(turret rotation), and CH6(blank firer). It only causes the turret to rotate about 10 degrees left, but the blank firer is a different matter. Having had it go off while bent over it switching it on, I have now fitted a kill switch in the supply line

Hope this helps

Nick, If you have one of the new power supply modules that supplies the power to the receiver. The problem occurs because on a 2.4 ghz TX/RX the handshaking between the two takes 2-3 secs after power up. Because the supply goes to the speed controllers straight away this causes the tracks to turn until the handshaking between the RX/TX is completed. Apparently it happens on some radios and not others. I have proved the point this morning by running the receiver from a separate battery and making sure the green light was on the receiver before pressing the red button on the PSU and lo and behold tracks did not move. I am going to fit a double pole 10 amp switch (with bolth poles connected together thus giving 20 amp capacity) in the positive feed between the power supply and the speed controller and then wait 4 or 5 seconds after pressing the red button before turning it on. Hope this helps. I'll let you know how it goes.

Dennis.

I followed Dennis's advice and used a double pole single throw switch and it all works fine,so thanks to Dennis.
I attached mine to the side of one battery next to my battery connections for ease of access through the hatch,I used the extra strong velcro which I have used to hold all my controll sytem and the batteries.
Its rated at 7kg on a vertical surface and suitable for wet and outside use.
My switches I found at Maplins,the DPST Toggle switch was £3.19 and I used 27amp cable.
If its of interest to any one I found a 30amp SPDT Auto 24vdc relay and I bought it while I was there it seamed a bargain at £1.98.
The SPST version is rated at 30 amp at 24vdc and for Marine and Lorry use so well up to the job.
I might use it on my Comet when it comes.

Hi Phil,
Yes I have been using mine for sometime now with no problems. I think you will find speed control module will be modified by the time you are ready to fit in the Comet.
