After a long work filled holiday, M6, the car built by my current team GDS Racing, is almost ready to run once again in the hands of Camborne School. The change from a chain driven gear hub to a single gear belt drive is finally setup but hasn’t been without its issues.
After repositioning the motor to sufficiently tension the belt, we then encountered the problem of it twisting on its mount. It however gets worse! On inspection of the motor we then discovered the shaft was moving in and out, something that should not happen. This will require a motor replacement on the morning of the race, not great, but with easy access to its mount it won’t take long to install.
If this wasn’t enough to think about, our first test run brought to light the issue of the belt slipping when under the tension of pulling away. On close inspection this was due to driving before full reassembly so easily fixed. This highlights the issue with a bolt together frame. To further help I also increasing the acceleration time on the controller, a more gradual force is now applied helping the car to pull away without the slipping.
All in all I’m quite happy with the prospects of the weekend, obviously not too happy about the morning motor replacement, but needs must. Also thinking levelled headedly, a win is not really on the cards with the teams that will be racing on Saturday, but I feel the aim of 80 miles is more than achievable, as long as we don’t encounter any issues…
