You need to pick up the M05 Version II swingarms, and chassis. You need to order two of the swingarms, as they come in a set of "one front, one rear" arm.

You'll lose most of the gold.

So I think I found out why my M05v2R was pulling left when accelerating. I checked the corner weights using 4 small scales and found that the front right and rear left wheels were carrying a lot more weight than the opposing ones. I checked the preload of the shocks, and the corners carrying the most weight were set quite a bit shorter than the others, yet those wheels touched the ground first when testing droop. :weird: I suspected the chassis was twisted, so I loosened all the screws connecting the front half to the rear half of the chassis, gave it a wiggle, then tightened it back up. The corner weights balance pretty close to even now with roughly equal length shocks. Hopefully it runs straighter next time I take it for a spin.

The pinion access hole in the bottom of the chassis is a huge mistake by Tamiya. Including tape to cover the hole is a Band-Aid that just doesn't work. I designed a reusable plug. I printed mine on my home printer and I'll try it out this week. I have uploaded my design on Shapeways for sale.

I posted this a long time ago but if your car tracks left on throttle while it coasts straight, easy remedy is to raise rear right ride height by a 1/2 turn or so on the damper spring seat collar. The benefit of running the hopup aluminum housing dampers vs the spring perch dampers to get that refined sus tuning. :)

Obviously it works the other way around too.. if tracks right on throttle raise rear left ride height.

I had already attempted to compensate with the collar adjustment, with 5 or more full turns and it still wasn't enough.

I had the same problem. Not sure if it'd help, but I backed off a bunch of screws, twisted the chassis around a bit and tightened it all back up. Seemed to help.

Nice CAD skills! :D Wish I could do stuff like that. For real car mods too.

Ok, my turn.

I put the blue/white spring combination on my M05. It seems excessively stiff. Even the red/yellow setup seems far to stiff.

Is this compensation for the floppy M05 chassis? Or can going down the "really soft setup" rabbit hole be the right thing to do?
