Seeking Info From other Cubmobiler's

Post by sporty » Wed Apr 27, 2005 1:26 pm

As You may have seen on my other post. I am trying to give info and help and tips in building a cub mobile.

I am looking for info from winners of cub mobile racers, including 2nd and 3rd place.

What info I am looking for-

Length of track

Was ramp used or downhill

Weight of Vehicle

tire/rim size used

bearing or non bearing, sealed or non sealed

And If you have the time, example by stop watch of the race.

Thanks

sporty

I wanted to add in,

That Comtech, AKA northwest.

A good Company and good people.

My goal is not to say there product is bad or not good in anyway shape or form.

My goal is to look and find a good competitive rim/tire for cubmobile racer's.

They provide a good wheel at a good cost to cub mobilers. I feel we just need to ensure good data and testing and information.

There may be better tires/rims that can provide a more competitive race for them.

I Don't want them to be face with getting something they feel is fast and to find out that its slower than what you previously have. Like my situation.

We used the 8" Commtech wheels with bearings.
We had a heavy car (we used 4X4s for the front and rear axle beams).
I think the total weight of our car with a 54lb Cub was over 150lbs with a load of 50lbs of bricks... I will try to check our weight more accurately.

Our wheels were supplied with sealed bearings ... 2 per wheel (each side of the hub bore).

We used steering linkage to give control AND to push our CG to the rear (like a Pinewood racer).

Just like a fast Pinecar, we would be even with competitors right to near the bottom of the track, at which point our car would lunge ahead by 1/2-3/4 car length (as our car continued to accelerate since the CG was still up the ramp a bit). This was a tremendous safety advantage too, as many a time in our 6 runs the other Cubmobile would wreck, but we were far enough ahead to be missed :)
