Basis: Design rules and figures from the cited sources; example geometry by Xem Studio

Sizes: see table below
- Rear-motor 2WD buggies hang the motor behind the rear axle, putting weight on the driven wheels for low-grip tracks and strong acceleration but with a tendency to wheelie (RCTech forum).
- Mid-motor layouts centralise mass and lower the yaw inertia, so the car turns in and straightens with less effort and slides more predictably; racers describe them as better on medium-to-high grip (RCTech forum).
- These are racer reports, not measured data.

Rear-motor benefit  more rear weight, low-grip traction  RCTech forum
