[Dagger Thrasher]

All of the McAllister oval shells are skewed with exception to the velodrome shell; I emailed them to check. Annoying, but true. I wonder what shell Nic used (Mod Man, sorry, I'm not sure if you're being serious or joking there?...hard to tell through text lol). I do have another shell that I'm looking into though, which may do the job.

RevRacer, yep...it'll be tricky. But with the right tyres and gyro - even if dialed out at high speed - it should be controllable (Nic demonstrated that with his Intimidator which can't be much heavier...and without a gyro I believe). The stock F103GT uses a material called CSC...at least, something very similar. It's kind of half-way to carbon fibre, with it using fibre glass for every-other layer, instead of carbon for the whole sheet. It's cheaper, and almost as rigid as carbon...but also a fair bit heavier.
An outrunner isn't a bad idea, but it'd require a complete re-engineering of the rear end...and would also mean that I can't have a diff. The current setup should be still quite efficient, and much easier to make. Thanks for the idea though. :)
