Thank you to all who post here, what a great source of information! Only wished I had found this forum and DD4H before our pack race and before wasting time and money with out of date and/or bad info and vendors selling bad tools and advice. I got my first DD4H order in today, and I am sure there will be many more to come.
The amount of thought, time, and testing that you guys have put into figuring out the puzzle of building these cars is crazy and at the same time very intriguing!
Despite all the things we did wrong this year including over polishing the axles making them too narrow, using the hub tool and reaming out the tire hubs - we had excessive tire chatter, and the list goes on and on.......... He won first in his wolf den race, and placed 5th in the pack. Only .001 from 4th and .003 from 3rd. The car is a three wheel but has straight axles and straight axle holes both front and rear with a 1" COM and racing on a aluminum track (not sure of the manufacturer).
He gets to compete in the district race that is coming up soon. The district race rules say no construction after the pack races. I interpret that to mean no new car building, but tinkering with tires and axles would be OK?
Is it possible/practical to re-drill and change the two rear wheel holes from straight to a 3 degree cant?
Rules say that the tires can be re-positioned (slots don't have to be used) but the original 4 3/8" wheel base must be maintained. His current car design wont allow for the front wheels to be moved, but for next year is there any benefit to moving the front and rear axles rearward? I understand that the further back the rear wheels are the better, and lengthening the wheel base is better, but is the benefit of moving the rear tire placement counteracted by the front wheels moving rearward to maintain the original wheel base?
Finally, is the axle straightener from Pine Car a worthwhile tool for correcting slightly bent axles or does it cause more damage than it does good?
Thank you all again for the great information and insight given in these forums!
