[QUOTE=RCP57;94574]I'm not sure what would cause the voltage drop. I know that happens with my Volvo occasionally because the slew ring I made doesn't always make good contact but I doubt a wiring connection is your problem. I have learned the hard way though that it takes a tremendous amount of power to turn a heavy model on grass or carpet. You may find that your motors are just not up to snuff. The machine looks awesome though and seems to function perfectly on smooth concrete so I'm sure if you can up the power somehow it will be fantastic!
Thanks Reg,
I now have 4s lipo and have set the speed controller to 100%, so at full charge on the battery I get 16.3v. This has made a big difference. The speed is too fast for scale so a change in gear ratio is coming in the next week or so. I am waiting for a delivery from Germany for some new gears from my friend.
This will make the scale speed better and have a lot more torque.
Here is a new video. Hope you like it.
