TA02SN (Short and Narrow), a mixture of new Tamiya bits (TA02 and M03) and homemade bits from aluminium sheet. No expensive specialist carbon/Alloy bits!
Got the idea from the fact that a Manta Ray ball diff set fits both TA02 and M03. The chassis consists of TA02 gearboxes mated to M03 suspension/drivetrain components with an extra set of axles and driveshafts added at the rear, this give a track of about 160mm and a wheel base of about 210mm. The chassis consists of homemade sheet aluminium plates (modelled on TA02 FRP chassis plates), upper suspension/shock mounts, body post mounts (using stock TA02 body posts to M03 layout) and a battery holder made from M03 retainers mounted on another plate. The propshaft uses Carson Joints and a shaft that was turned by a good friend. I have added a selection of TA02 and M03 hop-ups; one way front diff, rear ball diff, rear anti-roll bar, speed tuned gears, carbon gear shafts, steering arms from FRP chassis (with ball bearings on modified TA04 steering posts), a full set of ball bearings, adjustable upper suspension arms, toe in rear hubs, stainless steel suspension shafts, lightweight king pins. Radio gear and ESC is now installed on top deck. The shell is a Tamiya finished one, I don't like the windows but I have nowhere to spray at the moment.
I don’t know if it will handle any better than a FWD M03 but it should have decent speed (stock motor can certainly be improved on) and traction (I have another set of runner wheels with slick tyres).
