What size of batteries do you use? I also had some mid-air issues in Dortmund some weeks ago, running rear motor with full length battery (saddles). Last year I did not experience any issues with the original B-Max2 when I used to run with shorty batteries.
Last weekend I compared my old bodyshell (nicer paintjob
) with the MR body, and I sticked to the cab fwd afterwards. Steering was better and the car jumped better, too. If even an average driver like me can notice such a difference, cab forward bodies are not mumbo jumbo at all.
I've got a Finnisher on the way, which I'll probably run in mid-motor. Winter is coming!
