Thanks. :-) Wheelbase is 12.1", so on the shorter side of things...but that apparently makes it more reponsive in the air.
Battery fitment is tricky, but what I've come up with is to use a big, single 5 (or 6)-cell Elite 5000mah 35C LiPo in a custom RC-M battery tray, across the chassis in front of the rollbar and motor. I'm still waiting on funds to complete it, so I can't tell you how it runs unfortunately.
That pack is just the right kind of dimensions to fit without the battery tray showing over the edge of the chassis by much. I'll then just have the steering servo mounted "across" the chassis just in front of the battery, and hooked up to the bellcrank. There are pics of my motor mount design in that thread somewhere; maybe you could do something similar.
