Hi do all you pro's and non pro's alike! Our scout race is fast approaching, and in typical Duck fashion, I am WAY over thinking things, and making myself nervous! We had a tech day Saturday, the 22nd and my goal is to see how our cars do and hope for the best.

The problem is with a strict rule set, I don't feel like there is much I can do to fix any problem. Must use slots providing, no drilling. no bending. Each wheel must ride flat on the ground. All four wheels touching. Must use axles that come in kit. Must use wheels that come in the kit. How do you fix a wobbly wheel or misaligned rear end with those rules?

Needless to say, I've spent HOURS obsessing and working on these little cars with little to work with, trying to figure out how I can get it to run correctly without breaking the rules. This is how I set them up to run:

4" drift over 4', with one wheel floating. It still turns, technically touches, but just barely. Then I took 4 feet of plastic test track and let them ride down that. All of my cars scrapped the rail with the back wheels! They shouldn't, should they? I spent painstaking hours to get them to not to. So now they run 4" over 4' and on a 4' test track, at the end of the track the back wheels center the center lane. They also all seem to run down my tuning board fast, comparative to other cars I've worked on. I'm confident they are fast.

Is this right? Or would I have been better off leaving the back wheels as is, scrapping the rail. I'm worried that I've gouged and turned and pushed and pulled the axles into submission in there slots and slowed them down too much! They still seem to be fast, minimum wobbles, not erratic...but...

Overthinking this!

I guess basically what I'm asking is if I set my cars to drift 4 inches over 4 feet, and finagle the axles so that at the end of a 4 foot test track, they are center on the rail...should I be good?

Or would I have been better off leaving the back wheels as is and taking my chances. I don't want a back wheel to be fighting a front wheel for alignment at the cost of speed, but also don't want to scrap the rail with the back.

By the way, i'm TERRIFIED our cars won't pass inspection! After all the adjusting, and above all else, after dealing with the imperfections of the slots, it took maddening amount of times just to get 4 wheels touching! The stock slots...not a single one of them...when you insert the wheel, they do NOT like to be flat, not perfectly. Or straight for that matter. I just don't see how they can expect ANY scout to be able to get a car to touch all four wheels and be flat on the ground...when I can't even do it!

It's all good. My kids and I have made three cars so if one fails, next up in line. My sincere hope though is their main ones, the ones we spent all our time on and I feel will be the fastest. The ones going 4' over 4" and avoiding the center railing....that those pass.

Thanks you guys in advance for easing my fears, or heightening them.

PWD God's be with me now!
 
The 2 dumbest rules are graphite only and 4 wheels must touch
Agreed! I worked on both graphite cars, my kids, and oil cars, mine this year. And by FAR oil is less messy! Antiquated rule in my opinion. Guess they are worried about oil on the track, but much more graphite gets on the track than oil applied correctly.
 
I would took 1/16 off the front sanded it real good so it blends in and say your block must be crooked
Spoken like a true pro! I honestly may do that. I think they are pretty lax on check in. It's volunteers and we've never had a problem before. But I've worked on these cars HARDER this year, and if we did have a problem, simply pulling an axle out would kill everything I've done!

I may see how there cars do Saturday, and if they don't do well, build one more car each...if my wife doesn't kick me out of the house for the idea of MORE cars (18 and counting). Go ahead and shave off the 1/16 and hope it isn't noticed and if it is say I go a bad block...er TWO bad blocks! Heck, I guess why I'm at it bend a few more rules.

No, I don't know, definitely don't want to teach my kids the wrong thing! Thing is, I don't want to cheat, I just want to alter to make the stock block of wood straight like it should be! I think that's what I've done.
 
Thats the problem with these dumb rules the cant really enforce
Yes. I KNOW what they are trying to do. They want to even the playing field for the have and have nots. I'm definitely a have not, but willing to put in the time, resources, thought, engineering and effort to run a have car for my kids.

I'm not even worried about my race, just don't want to let them down.

Thing is, with a strict rule set, they are trying to even the playing field, BUT what they don't seem to realize is very few blocks of wood have four wheels touching out of the box! And getting them to touch is way out of a scout skill level. So the race boils down to who has the straightest block of wood, who has the least out of round wheels, who has the straightest axles out of the block. Luck. To me, it's about hard work and research. If a few scouts want to make there car fast, let them, don't leave it up to chance of manufacturing defects. And they shouldn't require a car to have four on the floor and flat, that means dad's have to get too deeply involved to fix it. The blocks are imperfect, allow for that so the scout can do the work.
 
I build a few cars. I drill them with drill jig then cut the slots back in and half of those dont touch..so i have break the rule and put slight bend un the axle no other choice..its stupid
 
I know I'm about to get preached too...I know I need a jig, and DO plan to buy one. But has anyone use The PRO Driller Tool?

If I end up making another car, thinking about picking this up so I can at least drill straight holes and give them a chance, I think it will still make use of the stock slots and go unnoticed. Seems to have good reviews, and might work for a scout level car and in a pinch for a non-financially-gifted dad.

It is! I worked for HOURS to try to get the darn wheels to touch. I was bending the axle in the slot til it touched, then gluing in place, which got wonky. I then decided I would try wire. I have a few gauges of wire. If the wheel is far off the ground, I cut a small length of larger diameter wire and insert it into the slot and put the axle in. Usually works. If that's too much, I use little thin floral wire. I can bend this back and layer it 1,2,3, etc... deep and get whatever heigh I want. To make one wheel barely touch, I put the floral wire in the slot of the dominant wheel, it seems to give it just enough boost so the other wheel touches and rolls, but otherwise spins freely.

And I admittedly DID break down and bend an axle or two, but not to gain advantage. To try to get it to touch and straight! I finally said screw it, they can't fault me. I've worked on this darn wheel for too long. I'm not going to cheat, but I am going to bend it and be done.
 
By the way, I should mention. I DO have a DD4H body with 4 wheels touching. I'm semi-curious to put it through the inspection process, see if they pass it.
 
Too much slop all the way around. I'd eat pb&j for a week or two and buy a better jig, e.g. clear jig.

Duck, you are beyond disappointing your kids. You are spending time with them and teaching valuable life lessons. Hug and kiss your kids. Tell them you love them and that you are doing this together. Sure, derby night will be exciting. But the big payoff will come years down the road.
