Before I go on I have to say an engineer who lives in a land where ±1 micron is a large tolerance I have to say how brilliantly the ZX6 goes together, the RB6 is truly world class but this kit is out of this world brilliant in the fit and finish department. The other point I want to make is that before you go throwing masses of aftermarket bling and even the Kyosho upgrades at it build this kit out of the box .... it's all in there, everything you need! I'd arm yourself with a couple of pairs of Xgear springs and take your kit built car to the track, nothing else
needed!
A couple of points from my build ....
1)
M3x18mm cap head screws to bolt the tower mounts to gearbox cases.
I did this on the ZX5 as if you round a head off you pretty much had to destroy the tower mount to get to the recessed head to get it apart .... on the ZX6 some of those recesses are very deep so I strongly suggest you do the same (never rounded off a cap head with a 2.5mm hex)
2)
Shim up the steering assembly - until you build it you'll have no idea of HOW picky I'm being here ....
Kyosho have done an absolutely amazing job of tolerancing all the plastic parts on the ZX6, the fit is out of this world brilliant.
That makes the tiny tiny tiny amount of play in the steering setup stand out like a sore thumb (it is a tiny amount) so I fitted an axle shim under each lower bearing and all play has gone and the steering is like silk.
3)
Aluminium spacers under ball studs
With time and flexing the plastic spacers will yield a little leaving the ball studs a fraction loose ... that play = oval holes = stripped thread.
Kyosho's plastics are without a doubt the best in the business but it is always sound engineering to use metal spacers / washers as they just don't give .... standard for all cars I build.
4)
Grub screws in all empty ball stud holes
Helps keep the plastic flex free and supports the plastic around the holes with ball studs in when you go cartwheeling down the straight ... again standard on every car I build.
Build was truly a pleasure, so much so I want to build another one right now
