Anyone else experience some troubles installing the motor in the 07's???
Looks like I have to add spacers inbetween the motor and the heatsink for it to fit comfortably!!!

Ok I have a gold edition m05 with no droop settings what do I need to convert it to a square pack and be able to set droop without putting limiters in the shocks

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 also need to eithe rorder the M05v2 pivot pins, or some longer screw pins for the rear arms. Finally, you need 4 m3 setscrews to do the droop settings.

You'll lose most of the gold.

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?

You actually get a complete set of arms with 54606, no need to order 2.

If you're using an alloy motor mount you'll want to get the v2 version of that too.

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 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.
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.

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

I had already attempted to compensate with the collar adjustment, with 5 or more full turns and it still wasn't enough. The car was tweaked too much for fine adjustments like that to help. Fingers crossed the weather will hold out for some testing this weekend to see if it's now fixed.

Trust us rc guys to over engineer when tape will do. (I'll probably order one.)

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.

That's exactly what I did too, just haven't had a chance to track test the results yet.

Thank you, sir! I design in SolidWorks for a living so I've had some time to develop at least some skills in the software!

If you ever want to try your hand at 3D CAD design download AutoCAD Fusion 360. It is free for hobbyists and there are tons and tons of good tutorials online including excellent YouTube videos.

Well I am an engineer and I'm part German so maybe that explains it! I really don't think this is overengineering though. I personally believe Tamiya should have included a plastic or rubber plug, similar to this one, in the kit. The tape is a Band-Aid and if you listen to the manual and only put tape on the bottom of the chassis it doesn't last more than a run or two.

Which spring set?

The short spring set that is usually recommended for the M-05 is pretty soft. I think you may have one of the hard on-road sets meant for touring cars.
