Im talking a scale 1/4 mile track and im thinking like Mike Swiss at 1.15 to 1.25 that is what im shooting for. Time will tell.

[CoastalAngler1]

I'm thinking weight and no glue 4wd w resistance on 2 sets of axles and 2 gear meshes...then again there might be some extra horses in that beast H Power...I'll be surprised if she beats 1.35.

Avg 16D proslot motor times with a 90 gram car and glue usually run around 1.00 - 1.05 on a scale 1/4 drag track w 16 volts.

1.55

heck ! Let's just go 36V and smoke all four tires !!

Its comming along bit by bit. I recived my order from PCH nice and fast.

In and out with long John to get the drive shaft done and next time the motor goes in it stays for a while. I cut the tires down to the hight of the ones from the model but im not going to norrow them untill a shakedown.
I did the front body mount and the rear is next.

Really nice Joe!  Now the ultimate question: will it burn rubber...or just burn?    Build-on!

I've gotten some nice soft tires for it and im hoping it will run without glue.
im starting with 16/62 =3.875 gearing so it is not to hard of a hit off the line and I think Lil John should have plenty of torque.

Weight distribution feels really good 4 wheel drive and the drop arm, I think will be a great combination with Little John.

Nice Job Joe, and congrats for getting to this build so quickly - I'd still be thinking about it! 

 

I'm not that familiar with the gearing on can type motors: does it need something that high? (as opposed to the 2.5:1 or so on the padlocks). Especially if it's got as much torque as we assume, should be able to lower it to 3:1 or so. 

 

What kind of gearing do the S16D cars run?

[Joe Mig]

Its got tall tires and I think its a good starting point. S16D close to that ratio with inlines some times higher.
Time will tell when I get to try her out.
we'll see if it runs out of breath before the finish line. I could always change it.

[dc-65x]

Neat build Joe....and John!

 

.............we'll see if it runs out of breath before the finish line........

 

I will lean towards a lower gear too Joe. Personally, I find it easier to tell if a car is "running out of breath" than to tell if it's still pulling.

 

Onward!

I sure hope it goes straighter then that Mike.


So both body mounts complete and this is the stance. A bit high but the olny choice I have wirh the tall tires all around and I wanted the rear to sit the same as the front and not lower.
all in all not bad.

[Joe Mig]

Time for the last chassis bath.
next step is assembly of the motor and chassis running gear.

[Joe Mig]

It lives !
Today I mounted the motor and set up the drive line and fired it up on 6 volts 4 D battery's to get an idea if everything is okay. It was surprisingly smooth so I broke it in at 5 volts on the power pack for a few.

Kind of a special moment when I was setting up the gear mesh on the second side and the tires on the other side were moving. Somthing I've never experienced before.

The tires I used are just for this test because I want to round off the edges on the set I'm going to use.

[Joe Mig]

I have a realy good feeling about this car. Tires and drive train all done for now. This thing is nice and smooth. I did not lock down the guid flag just in case i want to take a few easy laps.

Im going to use the wheel insects from the kit and then do the body next. I think ill put it on the track to get an idea on how its going to run.

Definitely the heaviest drag car I have built so far but with Long John in there it should be like twice the power.

[NY Nick]

Sets nice

[Eddie Fleming]

The stance and the big tires look like an old school short track stock car. Nice work. 

[Samiam]

Looking good Joe.

 

Let me know when you're going to SAL for a test run. I'll meet you there.

Yep I like the old modified stock cars as well.
The Hairy Olds is a twin motor 4 wheel drive drag car.

Love the exhaust pipes...are those hubcaps?

Those are original Tornado wheels made for front wheel drive automobile.

[Joe Mig]

Not bad for the first runs, the first few were in the two second range and I didn't realize the rear drive shaft was slipping and thinking I was spinning tire I use glue a bit disappointed.

After inspection is when I realized the drive shaft was slipping so I had Sam Reesolder it for me as he was at the workbench at Slots A Lot and put it back on the track going a 1.7 at 25 miles per hour.

That was enough I wanted to take it home and clean off the tires and maybe true them down a little bit since I think there was too much tire on the car.

The car leaves the line very nicely without the wheelie bar.

I think I will have to try to find a 17 tooth gear because the car was running out of steam about three quarter track.

[CoastalAngler1]

This thread is too cool, when the car is detailed and tuned you'll have a keeper for sure!  Congrats Joe.

 

Try a set of .435 tires...or even a set of .300...if you can get the wheels to ride somewhere other than the normal glue strip down the track, the car will probably like skinnier tires.  Are you planning this for a bracket beast?

Yes a bracket car for sure and I'm sure going to make it look pretty.

Yes I plan on moving the tires outward just a bit more and narrowing them down.

Ill be happy at 1.5's.
