POSSIBLE MODIFICATIONS TO IMPROVE PERFORMANCE:
- General weight reduction , in particular use carbon fibre axles which
give a weight saving of 120 gm. - Reduce frontal area and improve shape to reduce air drag.
( Drag figures of 0.48 N at 8.4 M/s and 1.91 N at 16.94 M/s were
measured in wind tunnel tests) - Use an aluminium drive wheel to reduce rolling resistance due to the
“O” ring tyre.
