OK So I had my second event in this car today. I hadn't fixed the batteries yet so I wasn't expecting much. I was really treating it as another opportunity to test the car and identify anything else that needs to be modified. The event was a Khanacross (similar to an Autocross). The car performed almost exactly as I expected. It would launch fairly well (about 0.5 G) but then after the first 10 seconds I would struggle to get more than about 0.1G and sometimes I was only able to maintain current speed with no acceleration at all. You can see I was forced to over compensate in the corners in an attempt to maintain speed. But my suspension needs work as its not turning in very well. The car was far from the slowest on the day and showed a tonne of potential. Even just fixing the batteries (without altering the suspension) would probably have put me up amongst the front runners.
Really I have three things to change:
1.Batteries - If I can achieve consistent acceleration throughout the course I will be awesome.
2.Camber - The right front is at 0 degrees will the left wheel is at about 3 degrees. I think matching them both at 3 degrees would be my best guess.
3.Ackerman angle - The chassis is about 10 inches shorter than the doner car where I sourced the hubs. So the angle of the front wheels when turning is far from correct. As I corner the outside wheel is trying to turn significantly more than the inside wheel. This means they fight against each other and the outside wheel scrubs and pushes resulting in severe understeer.
Here are a couple of videos from today:
