Going through mental checklist of mini parts, th only stuff that is transferable from old to new (besides fasteners, wheel hexes and the like) are the dampers, spur gear and rear axles.

Tony - you mentioned in one of the build vids there was a new ESC on the way. Is this a new HW? Is it really tiny! I've mounted one of my Justocks (old one) and it's a bit of a tight fit.
