All I know is, a Losi 22 won the EoE Regional yesterday, another came 3rd, the highest placed Cougar went in the bin after the finals
Both 22s were rear motored.
I pretty happy with my 22, haven't run it much, so not fully set up yet, but it feels pretty good rear motored, mid was ok, but our track doesn't really have enough grass for it to suit me.
