MS8 26 Horizontal size adjustment (Aero city)

[theMot]

Everything else on the chassis seems to have a pot except for the horizontal size adjustment. Apparently you need a special tool for this? I have seen the sets available on eBay for $30 or so. Frankly can't be bothered buying a set I have no use for except for this. Is there a work around or does someone know the exact tool so I can just buy that?

I'm short about an inch either size so I don't think it is a matter of changing the size jumper on the chassis itself.

There is a jumper near the flyback and I think that's what you need to move it by an inch on each side. The H size fine tuning is done with the ferrite core pot but I don't think you'd get an inch out of it. They can be fragile so go careful if you do adjust it and only use plastic tools with it. Something like this set is what you want but you can likely find one cheaper with a bit more searching
