Well since you gave me a comprehenisve review, I'll try to do the same... :)
Love the car! Especially the 270hp variant, the other two are bit too powerful for their handling, in my opinion. Too easy to overdrive them and end up on the back in the brush. XD
Tested them on Endurodrome, as I do with all of my offroad designs, and they did well, for the most part. But I can definitely tell you focused more on handling smoothness and cutting weight, then resilience. The MacPherson front suspension is a major weakness, in my view. They are notorious for losing wheels very easily if they hit a bump wrong, since they only have one wishbone, as opposed to the Double Wishbone suspension design. If that wishbone snaps, the wheel flies off. None of the three models made it past the second lap on En, and all due to snapped-off front wheels.
Secondly, i believe a simple Ladder chassis would do better, for a heavy duty offroader. Even if it is a bit heavier then Monocoque, it can take more hits and bumps, and keeps the suspension safer.
Other then that, the cars are great. Lighter weight definitely helps, they are a bit more snappy in acceleration then my Lexxa, even the 270hp model. But Lexxa is considerably tougher, on the other hand, so... yes. Different design priorities, I'd say lol .
All in all, great handling cars, for most rally circuits. Just a bit on the flimsy side, when it comes to how much punishment can they take, on a more brutal track like the Endurodrome.
