[CMOTD]

Tried a bit of weight Hub but it didn't make much difference. However, have been mucking about with it so an update on things:
When I glued the errant rear wheel back on I noticed the other one was wobbling as well so some of the problems might have stemmed from them working loose. While gluing the second one I saw that part of the mounting for the front lights was missing and they were rubbing on the front wheel so the lights needed gluing as well. I also took the opportunity to replace the braids with thinner, more flexible stuff and nail varnished the front tyres. I don't usually bother doing anything with the front tyres as Scalextric ones are virtually zero grip on my track anyway but I thought I might as well see if it gave any improvement.

Back on the track and performance is somewhat better, can now lap at close to 6.2 seconds which is 3 tenths better than before but nowhere near a competitive time. It still understeers off at random but not so often and I can usually manage 10 or so laps before it crashes.

Performance assessment is therefore upgraded from 'fairly rubbish ' to 'not very good'.
