Now Iīve learned that the motors in a normal digi q and in the combats are the same. I think the numbers on it mean that they are selected because the numbers allways come as a pair. The motors have to be the same rpm to go straight. Even this is their biggest problem - if you donīt let them run in for along time(till there is no more changing of the rpm) your combat will allways be trimmed to the left - then a little to the right - more right - to the left..... it never get a stabil straight going.
Btw my motor that kept fooling me - after a second long run in itīs now perfekt. They all need only a little trimming so that all four combats are able to rotate on a point what they call :
The "Super Turning" Function
- Press Right or Left First
- Then Press "Backward"
- Then the Tank can rotate at Same Location
This only works if your trimming is not too much to one side.
One thing I have to say is that you should grease the wheels on their "axles" becauce plastic turning on plastic will wear out after some time espacally the two frontwheels ! When i put them off after a short runtime I saw a little white powder - plasticpowder.
These little guys need some service from time to time.
Last but not least :
Washing the treads from time to time reduces slipping at the inside.
Itīs good to have this forum for charing our thoughts and technical information to reduce mistakes.
Donīt worry - be happy !
