Rear. I previously used the older RB5 wide alum hangers. Switched to the new ones with plastic inserts and it's binding (out-B). Any ideas?

Though I'm using these mounts in mid configuration (707 not 706) I used the steel bushings and the rear arms are completely free. Are you sure the plastic bushings aren't deforming?

Seems some people got lucky and scored some from kyosho america. I say they will be everywhere by February.
They're released, but sold out quickly.

Thanks. The delrins are new so no deforming. I will try the steel bushings.

I am using the 521-1 arms so I'll also try removing the 0.3mm hinge pin shim and see if they loosen up. Cheers,

One thing I did today that helped was go to 3.5 toe in. Also went pink front springs. I know sounds crazy but it worked

+1 on the 3.5 rear toe.
It was one of the first things I did with mine and liked the feel

Anyone know where to get Kyosho parts "on the cheap" in Canada?
