@ Tres if you want to go for no flex in the chassis you are better off going for the milled chassis as it is from 3mm carbon and as it is milled these areas are strong than cutouts, but the cost is high, the new "Ion" spec chassis with the cutouts will sell for £67.50 a lot less than the milled version, and had a tad more flex but is still a lot better than the standard chassis, even better if you use the carbon fibre top deck
@ Jimmy glad you got on with it well, hopefully you should of gained some more steering from the reviesd battery layout.
Hopefully the "Ion" spec chassis will be avaliable in around two weeks, I will still produce the milled "Atom" spec version but they are made to order.
