Here's my Final setup from Caldicot Indoors Christmas Bash 2010...
B44 Caldicot Setup
Just to confirm, I ran the rudebits lipo tray, but not the straps. Depending on the weight of your lipo's, I would run about 100-150 grams extra around the rear end/lipo cells. My lipo cells are very light (230g without wires), so would really like to have run both Rudebits tray AND straps, but didn't have any straps for today. Car was more 'steery' as the grip came up in the last two qualifiers. If your running the reedy lipos, just run the tray, and see how it goes.
My car is also almost a B44.1, bar new chassis layout, and shock bodies!
Hope this helps anyone.
