so I have this mr slotcar mazda, and was wanting to move a rear wheel out a little for tire/chassis clearance. Seems the normal slot.it type tool doesn`t fit the set screw. I looked for a reveiw but had no luck, anybody know the correct size grub tool?
Here's a link to a review, but post #33 by MRSlotcar says they are M2 screws, so they should be same as a SlotIt, also you could give Professor Motor a call, he's the US distributor.
Yes I agree they are M2 thread, but the standard 0.90mm - .035" driver is to small for the set screw. I know it`s not just my car because I tried it on another persons car.
Then I would hazard a guess that it is .035, and your SlotIt driver/allen wrench is has worn the the corners off, it takes very little wear to be useless, and the SlotIt versions are decent but not the best, get a high quality unit like the WIHA, or Sloting Plus, they fit much better than even the new SlotIt stuff.
Go back and try that Slot.It wrench again. If it does not work then replace it.....not with another Slot.It tool but with a high quality .9mm wrench. Let the tool do its' work. Don't try to force the tool into the screw, line up the tool correctly and no force will be needed.
Then I'm at a loss unless the screws themselves are stripped, I don't have any of MR Slotcar's product so I can't comment to the quality of the screws they source, but I've had some of the Chinese ones on SlotIt's go off. A M2 screw pretty much has to be a .035", set screws are made in huge batches and a there's no way a small slotcar company is going to be able to afford to get a screw manufacturer to make a special unit.
Be cautious with that Scaleauto driver though, as it has adjustable torque so you can screw things (like expensive wheels) up very easily when re-tightening if you haven't backed this off a bit from factory setup.
Both rear wheels and gear on mine are stripped out of the box.
This is what I was wanting to see, maybe this was the case from ist assembly. Evidently not to many have tried to remove the wheels. It`s not my 1st time fellas, I am very aware of how to do the task. Thanks for the input !
