Ear pieces / communication
Investigate other wheel sizes
make F24+ car from RR7

Possible Aerodynamics improvements:

Side air dams
Rear shape
Windscreen shape
Cover in top of rear wheels
Nose cone shape (More air under or over the car ?).
Around driver area
Rollbar aerofoils
Car tilt (Up at back or down at back)

ToDecide

To use or not battery heating ?
Compete with 2 or 3 batteries ? (maybe depends on what other top cars do)

Mid Season Ideas

Priority 1

Anaylse data logs from final and compare with CC. Look to see how gearing affected things etc.
Add GPS module to improve lap-timing accuracy for better average speed control. (JA + TB)
Investigate and Improve Aerodynamics. We need to gain 6% speed, most of this can come from aerodynamics. (GB)
Improve telemetry display on laptop and train younger members on how to use during a race. (Any takers + TB)
Increase the horn volume. Needs PCB designed and built. (GB,DD + TB)
Build battery desulphation units. We are going to have to make our batteries last the season if we can and we will be using these oldish batteries at the final. We need to put the desulpication unit in a box. (Any takers + TB)
Add themostats to new 12volt battery heaters. This will allow us to get the battries to a more even temperature (38 degrees ?) and provide us with more energy either for greater speed or if the speed limit rule is in place greater battery life. Need to make up 2x Maplin circuits and fit to heaters. (Any takers + TB)
Safety audit: Brake tests, Tilt test. (LT)
More sponsorship. (Townsland trust ??)
Seat belt fixing and adjustment for quicker pit stops. (LT)
Fix battery trolly
New chock.
