The rolling chassis is ... rolling!
Very easy build, typical of Tamiya.
The Aeration shocks - very high quality BUT... the standard o-rings completely bind the shock shaft so they have to be rebuilt using the low friction o-rings from Tamiya (part #40530). Once the low friction o-rings are in (with a bit of shock slime) you have to cut quite a lot of coils from the springs. Buttery smooth! I have also removed some of the internal limiters on the front shocks to give more droop. They are super easy to bleed and build bubble free! But if I was buying again I would not waste my money on these and simply get some 3Racing Mini-t shocks.
Also - the Hitec HS-85MG servo fits straight in by cutting about 1mm of the tabs each side and it's also a direct fit to the included servo horn.
My 4100kv motor has not arrived yet so for the moment it has a Tekin 6.9 in as a place holder.
