Thanks a lot for all the info! This really helps.
I'm located between Haarlem and leiden, pm for details....
So now i've got to get a hold of some pinions, i'll try bmtuning for them, Although i don't think i spotted these before. Where areyou shopping as I don't want to wait 3 weeks for a pinion from HK.
I also have a ezrun kit with an 8.5 motor but that would be way too fast. I'm searching eBay now for a 17.5 motor or kit.
