They need a big block engine and strong truck with steel CVD's to put it in as well. Things like that are where they are lacking IMO.
they need to get rid of the plastic sliders(along with the rest of the plastic in the drivechain) on all their RC's IMO, and replace them with either CVD's, or dogbones both I think would be an upgrade
Hell they can go do that and resell every single RC they make as a new model
