Hi OneKiwi,
I think also a 410 2wd could work very well, espacially on carpet tracks!
But when i was at the Eos last round here in austria, i saw jorns car a bit closer and i think, there was a bit more front kick up, than on the 4wd 410?
And i think, when he was changing the battery, i saw, that he had a shorty layout, with the motor in the back, like the tc2, but i'm not sure!?
And he was usin alot of waight in the back, too.
When you look at the xb4 and the xb4 2wd chassis, there is also more kick up at the 2wd.
May this help a bit?
