Thanks to All

This year's cars just left my house destined for check in. Two grandsons, both holding cars that are faster than any of our previous cars, and all the previous cars won first place, so here is to hope. I never ran their current cars against each other because I didn't want to know the results, but they are very equal.
This is to say thanks to everyone who helped me learn and tolerated my questions. Both with current questions and all that have posted in the past that I learned from in my research on this site.
I hope I learn enough to be able to return the favor. This site is a Gold Mine for anyone who wants to get serious about this game. Rock on.

 

Send them in to a league race & get a time, then you have a baseline for the future.

 

Scout challenge at Rocky Mountain Derby would be a great spot to race them!

 

I would like to do that when I get them back. I know that I can get a little more out of them because the rear axles aren't as good as they can be. I learned the importance, and method of tuning the rear 'bent' axle alignment with only a couple days to go, and quite frankly, I wanted them to be as close to each other in performance as possible. They were both beating our previous fastest car equally, so I stopped. I did not run them against each other, because I wanted them to find out in the real race with no pre-determined sense of win or loss.

 

UPDATE
They finished first and second with the youngest beating his big brother by a wheel. This was the youngest ones first race, and he now knows what it feels like to be a champion at something, just like his brother.
