Hi Trish, good call!
this is what I've done - car is really good.
This is more to kick off a discussion than to come across as a self proclaiming type...
I moved onto the 22 from a CR2. The CR2 was a good improvement over the XXX-CR "out of the box" (just by taking a XXX-CR kit and adding the AC bits) but the CR2 really only became really competitive after you balanced the car and weighted it up (used to run mine at 1710g).
You need to get the 22 onto four small weighing scales (ebay about £5 each from hong kong) and balance the car up 35% front 65% rear. And you need to raise the weight up to about 1700g (this is weight that the C4.1 Centros are running at). My 22 is superb, by far the best car that I have ever had.
I run the following weights;
105g (4mm of stainless) under the rear lipo (
one cell only)
35g over the gearbox
25g of brass around the frontal rear wishbone pivot.
10g - 3 degree stainless steel antisquat shim
35g inside the motor shroud and on the chassis in front of the motor
5g under the gearbox behind the front pivot.
Before I weighted up the car, the rear end was snappy. Now balanced the car is really really good. The back end rolls nicely and generates good grip - I've been clipping the outside row of spikes, gone back to the kit 4.0 LRC pivot and generally using pink rear springs.
I've been looking at all of the various aftermarket chassis' available - frankly I think they all lack imagination. The AC one would be my choice of the lot, but why not use a thicker carbon sheet and mill out an area under the motor for a nice big brass plate to slot into??? I agree with most that the car is a pinch long - I added 8mm to my CR2 and it was a huge improvement, but the 22 is another 6mm longer again....
We could also use a 3 piece gearbox housing - have a brass base that comes up as far as 1/2 way through the diff outdrives and they have plastic from there on up. I'd also like the gearbox to be a little more upright - means the motor could be raised a couple of mm and some weight could go in underneath whilst pushing it backwards also.
Just some ideas.... but I find the car really good - many don't
