Haha, loved the hybrid XXX! Got my XXX-mongrel working ace but it wore out and I reverted to a CR as I couldn't be bothered sourcing and dremelling more odd parts. Check out those kingpin ballstuds!
Would say this is probably the order of Losi 2wd effectiveness in the UK...
Hybrid > XXX-CR > XXX-KE > XXX-BK2
Not counting the venerable XX-CR, which would probably edge the BK2
