XRAY - Model racing cars

I bought a Hudy Excellent tire truer online but I'm not sure if it's functioning correctly. I'll describe it for you all and hopefully someone can tell me if it's ok or not.

I switched it on and it appears to work fine meaning it goes from left to right and back again. Fine everything is ok with that, but when I try to switch it back to move again to the right from the farmost starting position, it didn't move and the wheel didn't spin. So I clicked the switch back to neutral and then back to move right and it moved.

Q1. Is it normal it to not move right away after completing a full cycle?

During the move right across the tire, when it was a few mm past the tire, I flicked the switch to make it move back to the left and the wheel started stuttering and didn't have the smooth rotation it normally has.

Q2. Is it possible that I switch it too fast in reverse?

Please all answer as much as possible as I only have a few days to return it. Thanks.

I figured out what the problem was. I was using my power supply I use for my charger but it wasn't putting out enough volts. I plugged it into my portable power supply and it works perfectly. At least this is here for anyone new that might have this problem.

The motor in the HUDY tire truer is a very special super-powerful type (which is the big difference between the quality, performance and life of the HUDY truer to all the others) and this motor needs a solid power supply as you already experienced. The alternative is to connect the truer to the full size car's battery.

is there anything the excellent tire truer can do, that the power truer can't? (apart from being fully automatic )?
