1 week to scout race

Thanks MOFAST for getting that on for me. He put blue wheels on left side and red on the right.
 
We're aligning now and on the board I have her dead straight forward with the straightest BSA axle we could polish up for the DFW. The rears go lightly to the heads. Rolling it backwards, the rear wheel behind DFW always wants to turn in. I made a PVC track and she doesn't seem to wobble except my seam isn't perfect which causes her to fishtail for a second then she comes back steady again.

Are we looking to get it to roll dead straight forward and backwards then bend DFW and set drift or shouldn't I work about the backwards rolls? I don't want the rears to fight each other.
 
I think we're set. 2" in 4', our .10 oz tuning weight added 1/3 of the way back from front axle and she runs nice and smooth. It may be my imagination but it even sounded smoother there. I put it behind the rear axle and she still stayed on the track. I guess my DFW weight...COM concerns were all for naught.

Rear wheel behind DFW stays about 1/16" - 1/32" off the rail except for my seam which gives it a little tweak but she turns right back to the rail. Still doesn't go straight backwards but I couldn't get it to.

Thanks all for letting us jump aboard here with you. Maybe my church will go for a derby race with prep sessions and all to bring people in. Now though, I need my sleep.

I have to say too that MOFAST spent considerable time with us before we even hit this forum and if he's a 2-finger typer like me spent a lot of time helping us out. If I would have listened to him closer, sooner we'd be better off yet.

Thanks MOFAST.
 
some nice wood work cutting the BSA out! And very nice patriotic paint job!

You should send this in to the Mid America race as well...Id say it should have a great chance at the categories for most boy scout related design or most patriotic design...

Thanks all. It was a little stressful watching my 9 yo dremel those letters out but he did great. I wish we could paint like that but it's just a photocopy onto photo paper then automotive clear coat.

Now to build the Outlaw car for this Saturday. The plan is a 4wd dual motor electric, 9.6v with switch to turn power on, microswitch for the starting pin to get it going and microswitch on bottom to shut it down at end of track. My 7 yo daughter wants it painted purple, yellow and black stripes.
 
Awwww man! Are you kidding me?

That sounds off the hook! How are you gunna get that done by Saturday.

Please post photos/ video after the race.

Thanks,
 
All built into a stock BSA block of wood. I've got the motors recessed down into the block and have spur gears mounted on the inside of the front and rear left side wheels. Motor pinions run direct to the spur gears on the wheels. Wheels are mounted on solid 1 pc shafts running to right side where those wheels are epoxied onto the shaft. Wheels are "V'd" down the middle to help keep a rubber o-ring straight on surface of wheel.

It won't be pretty by any means and it may not even work as intended. I'll probably be wishing I had just run razor wheels on a 1 lb block of wood. If the cops get called because it looks like a bomb and the race is in a school I may be starting a new thread titled "Bail $ Needed".

If I can figure out the photo thing here I'll put a pic on when it's done.
 
THAT is totally cool.

Win or lose, I would not regret making that thing.

Go to Photobucket and upload photos!
 
Does that alignment method sound OK? Steer it straight forward and backwards on the board then bend DFW and set drift?
 
The Outlaw car has wheels, paint, motors and switches installed. Now that epoxy is dry I can align the motors with wheels and do final attaching of everything. I think a little Krytox on the axles with do just fine. Maybe next year I can Red Rocket the axle bushings on that Outlaw car.
 
I dont have anything to help you, But I wanted to add that that is a great looking car! I am very impressed that your 9 year old was able to handle a dremel in such a manner! I dont think my son would have been able to handle that.

Thanks. My boy knicked into the side a little too much and took off the bottom hook of the "S" with the dremel. He then learned how to epoxy a tiny piece of wood onto the "S" an re-dremel it. He also learned how to spread some wood putty to clean it up. I was a good bit anxious while he did it and probably could have been a little more patient but we both survived. After he cut it he used the palm sander to take it down and that really cleaned it up. Even if the car is a dud for speed it will have been a good lesson for him.

I'll have to taper the bottom in front. The batt is putting out 11.3 volts with fresh charge. U can see the blue ON/OFF switch between the wheels on the side, front microswitch and another on bottom. In front of and behind the wheels is a little white plastic guide so the spur gears don't grab the center rail and climb over. All works well. I hope I'm not having to pay for a new timer assembly.

Hey Davet,
I really want to say that this contraption is beautiful, but I am afraid that would not be the right word for it. It is AMAZING though! You gotta get some video of it! That is so cool!
We definitely have to talk. I have about 100 questions. Totally outta this world. Congrats!
