For those interested
I managed a days racing yesterday with the 222.
Track was grass, muddy & quite bumpy in places.
Basic set-up:
Mid Motor.
Shorty packs down the middle of chassis. No added weights.
Front shocks-550cSt/kit springs & pistons.
Rear shocks -500cSt/kit springs & pistons.
Tyres - Front-Worn Schumacher Green spikes with outer row cut.
Rear -Ballistic Green spikes.
5000cSt Diff oil.
The car itself was surprisingly good, took the bumps well, steering good & felt quite stable/predictable. I'm using the ARR electrics (3300kv sensorless motor/HK 60a ESC) & did suffer issues with what felt like interference when racing with other cars but not while practicing alone, maybe a receiver issue & I did notice the lack of 'smoothness' from the sensorless system. Both of these problems didn't make it easy to drive but wasn't the car's fault.
Nothing broke or came loose over the 4 rounds or 1 final. Gearbox/belt were fine, no adjustments needed. No signs of leaking from either shocks or the diff. I noticed the solid rear wishbones like to collect mud, as did the steering assembly to a point so had to keep on top of the mud throughout the day.
After the racing was finished I did notice some outdrive wear:
Time will tell how long they'll last, I have ordered a complete assembled diff plus another pair of outdrives as they're so cheap. Here it is after the racing:
Unfortunately at the end of the day whilst doing some casual laps I caught the piping after a jump, caught the rear wishbone resulting in a broken rear most hinge pin holder.. my bad

Luckily I ordered the last available spare set but a redundant TM2 v1 holder I have looks like it'll fit with some light dremelling.
I'll certainly give the 222 another go, I have a 7.5t sensored motor & a better ESC I can try & I need to sort the interference issue which I suspect is receiver related. Breakage aside I thought it did good.
