I am preparing to build a car for a new local adult race, and have some leeway that I am not used to with our standard scout rules. I can modify wheels and axles as I wish, and weight can be more than 5 ounces. I have to use BSA wheels and axles, and we are using a wooden track. Questions are as follows:
1. I think I read somewhere that there is a point of diminishing returns regarding weight, somewhere around 6 or 7 ounces. Has it been tested? I'll test it myself...
2. I plan to lighten the wheels, but have never done razor wheels. Are they stable with heavier cars?
3. Is it worth drilling holes in the side of the wheels to lighten them?
4. I'll be doing grooved axles for the first time. Is it worth it?
5. I'll have four wheels, but one will be raised as always. DFW will be done with the 5K method (delrin rod). This allows me to do any degree bend I want. I have had success with as much as 5 degrees, but never tried more. Is there more speed to be had with a different angle? 7, 8 or more?
6. We have to use graphite. Not sure about using Pledge in the axle process, since there are so many kinds. Which Pledge should be used, and how much does it help?
7. I usually have a COM of 3/4" to 7/8", as the track is bumpy. I plan to do the same again.
8. Other than getting perfect alignment using the Silver Bullet, is there anything I should definitely do (i.e. fenders, COM, etc.)?
Thanks.
