Well, tonight I was cleaning up the wiring in the Sturmtiger and getting her ready for the weekend Tank Expo at Ft. Snelling. Ran into some really strange issues. The first being that when I would fire the marker, my traverse motor would jump. Only in one direction. The switches were mounted right next to each other and installed so that I could kill the 12V power in one fell swoop. That switch fed the trigger switch. I designed it that way so I could disable the marker, but still use the turret traverse. To fix that problem, I remounted the traverse switch on the other side of the tank and put as much separation between the wires as I could. I even ran two separate leads from the secondary 12V battery I installed to run the Vantec RET411 speed controller attached to the traverse motor and the 12V door lock actuator thinking I was getting an induced current in the traverse motor lead when the marker was triggered. But none of that stuff fixed the problem. After messing with that for quite sometime I said to myself, I'll fix it later. I then reconnected the speed controllers to go for a test drive. Hmmm....only one track moving. Found that one of my cables wasn't seated. I thought, problem solved. Then I got no response from either speed controller and they were blinking like they had no signal. I looked at the IMX track mixer and the light was off. I thought it was toast until I moved the traverse and elevation on the gun and it sprung to life. Then I moved the elevation again and it died again. Long story short, it looks like the CS80 1/4 scale servo is drawing so much power that it's taking it away from the mixer. When I unplug the CS80, all is well. Plug it back in and the problems come back. I then put fresher batteries in it and it made the situation better. I'm thinking that I need fresh batteries to resolve the issue completely. With the fresher batteries, the traverse motor jumping occurances lessened when I triggered the marker. My volt meter shows the batteries putting out 6.2V. I guess my question would be, has anyone used a larger battery pack for their reciever when using these large 1/4 scale servos? I know I can't increase the voltage without blowing the reciever, but what about mounting another 6V pack in parallel to accomidate the current draw? I guess another option would be to get a 12V to 6V regulator to run the reciever. Any thoughts? I'm using a Spektrum DX6 radio with BR6000 reciever.
