Similar to frizzen's mod is shown in the pic. This mod seems to be very easy to do although I've never tried it. With the setup shown, your best bet would be to dual-cell your bit with the zipzap SE batteries which are 10mm dia x 10mm lg. You can order them through zipzaps.com (look for the faq section). You simply split the two batteries by cutting the shrink wrapping in the center, bending the contact so the batteries lie side by side and finally solder wires from the battery contacts to the bit charging contacts (it's easier to solder the wires on the batteries first). The batteries should fit in the open space shown in the pic (between the purple suspension bar and the motor). This is the easiest way to dual-cell a bit. Unfortunately the batteries are only 70mah in capacity, but if you utilize two motors that should make up for it.
In my opinion, dual-celling with a heavier high capacity battery and a high torque motor is the limit in terms of speed for actual racing. Any faster than that, your bit will flip which will pretty much knock you out of the race. But then again, I only use single speed bits. Also, at the very least you need to widen your rear wheels as shown in the pic. Zipzaps have the extra wide wheel kit which will fit the bit chassis, but traction is not so good. The best wheels to glue together are Motorworks wheels (sold at Walmart). They have knobbies which will give you the best traction.
Also, if you widen the rear wheels and your antenna is stiff enough, your car can probably recover by itself if it flips over. I have my car designed where the rear wheels will always make contact to the ground when it is flipped over. I hit reverse and my bit will fly forward and land upright. Dual-celled mosfetted or dual-motor bits are faster, but in my opinion too fast for racing due to their size.
