Just a few things to note about the Exotek chassis having just fitted one.
Just in case you were thinking of getting one you might want to bare these in mind just in case it doesn't do what you require;
The two holes in the chassis near the centre line used to be used to mount those small plastic nuts as a 'limiter' so the lipo couldn't come into contact with the belt.
On the Exotek they are not far enough to the lipo side so they are no use.
There was also a hole dead centre of the chassis and just in front of where the hole is in the top deck (for the belt tensioner), this is also missing.
The cell tape slots weren't wide enough for my Much More cell tape so I had to enlarge them.
Where the servo mounts near the centre line for the modified servo position, it meant my KO servo mounting 'ears' were actually rubbing against the lower part of the belt.
I have the same servo they use in their pictures, but mine was actually rubbing;
I used the Zeppin steering centre link, but the mounting holes for the ackermann ball joints are slightly lower than the originals (dead centre) so the rod end for the steering link rubs ever so slightly on the belt. Not sure if the Exotek version would solve this.
Apart from the above the fit'n'finish of the chassis is excellent.
Once done the steering now requires a lot more movement from the servo to go from lock to lock, on mine 89% one direction and 115% the other, both were around 60% before.
This gives better resolution to the steering through it's motion of travel, but it also slows the steering down as it obviously takes longer to move further.
I will take some pics tomorrow in daylight to show you waht I mean with all this.
