Shorty pack for TC, that would be sweet.
I'm seeing an Mi4 with in-line LiPo, servo on the right side and ESC mounted on the left side of the chassis. Three belts, front on the left in-front of the ESC, main belt on the right behind the servo and the rear belt in the same position as it is now. Maybe a bottom loading battery tray like the JRX-S. Loads of cool anodized alloy parts & carbon fibre... drool
OR a sideways LiPo position like 1/12th.
So much you could do with a chassis developed around a shorty. This could be the next revolution in Touring Car. Sign me up.
