Look, I only go thru all this hassle cause the M05 ball diff does not create any level of confidence. That little 2x25mm diff screw worries me and the outdrives seem to be very soft from the ones I've seen. Tamiya is selling them, the screw, nut and nut holder, for $6. It shouldn't cost them more than 30 cents. Somehow that just doesn't seem right. Nothing against them making a profit, but -------
The 2mm screw is what most TC cars use and they don't have any more trouble with that than with anything else. If a mod TC car can use that screw, I don't expect you would have any more trouble given you have much less power. Try it and see how you go.
I have to mention here, quite a few people at our track broke that screw in TRF cars and my impression grew that it was something to do with Tamiya and their screw/diff. They then changed it to a "normal" 2mm capscrew you can get at most screw places and problems went away. No reason to buy the Tamiya screw if you don't really like it, and I agree it's expensive for no good reason. But then again such is everything with Tamiya.
The only change is that you may have to use a hex driver to adjust the diff if you don't cut a slot in the screw head.
