Re: Geetting COM Under 1/2" ???

Sure. The issue going less than 3/8th of a inch. Is it become very hard to control the car. More drift needed. Friction from more drift. Then becomes a factor. When you start trying to go less than 3/8. The number of people who can do it and go very fast with it. Becomes a very small list. I recall ...

Re: District Results -- Car slowing way down

After you check your alignment. If you find no changes there. It is also possible. There was not enough weight placed on the lower part of the track. Below the legs for staging section of track. There's always a few things to look at. Freedom track has a slightly different arch. The one at one of th...

Re: small diameter axles vs larger?

I'll try to get a pic in today of my BSA axles. I've got ones already polished sitting at .090". I think we're all kind of wondering. If youre micrometer is reading wrong or if you got a hold of some axles that are what many scouts would like to have. If you truly got some .091 reading. Bsa sc...

Re: District Results -- Car slowing way down

Alingnent.

Other then that. Staging.

Could have had ruff stop section that caused a axle to hit.

Uneven lane.

Many things can cause it.

Re: small diameter axles vs larger?

Every stock BSA axle is oblong where the wheel rides. Have been for years. .091 on the high side and .084 on low side. All I can say. Because I have no interest to get into this as a debate. I personally have not ever gotten a .091 reading on a stock bsa scout axle. Since I started checking them. T...

Awana and other axles are.langer then stock be a axles. Those larger size axles. Changes my reply. That information was left out of yo...

Re: small diameter axles vs larger?

No. Because a oblong axle. Stock size. Is still not filling the wheel bore gap. It's not resolving the gap. It's still a .086 axle. People use too and maybe still do. Make the wheel bore smaller. Melted plastic. Ect. Several coats of wax. it is harder. Much harder. Because you have to have the tools...

Re: Times for 35' Best track

Bill. the hardest thing with that. Is packs or others. 1. Have the track set up the same way. Height. Starting system. Timer system in the same place. So it's hard. 2. Then reaching out to find someone who has same rules . Hard also. 3. I'm sure there are cara and same track that have gone faster. S...

Re: Air Ram & Ram Jam, Projects, Prototypes

Interesting. It's nice to see someone tinkering with the idea. I agree. Weight and added overall mass . Will be a issue. That why in my tinkering I did things a bit didifferent. However. You can tape and cover the hole for a run or two and see if you see a time difference. I wanted to do this with m...

Re: Rail rider question

However, its the design my son came up with and wanted so I wasn't about to tell him no. Thanks to your he...

Re: To Shave or Not to Shave the Hubs

Back in late 2098. I modified mine. And I think it's very important to reduce hub to axle head friction. In fact I had posted on here. How I would polish my hubs to a nice shiny plastic before burnish some graphite. In graphite racing. Faster car and times don't drop off as fast. In a longer running...
