tube choice
« on: October 02, 2011, 08:59:42 AM »
What would be the best tube thickness to use in a front engine truggy that has 435 horse?  I am thinking 1.5 .120 for main structure and 1.25 for the rest. What would you guys use?

Kind of hard to answer without some more details about chassis design.

Also, play car or race car?
1.5 X .120 is going to be the minimum.
1.75 would give you a lot less trouble down the road.
Cross bracing, try to keep the diameter up but go down on the wall thickness, like 1.75 X.095 or .083. Most chassis crack at the welds, the larger tubes have more surface area on the welds and tend to crack less even though they are thinner wall........

 You would save money and a lot of time by buying a set of plans.

Google V drive. They use  it a lot in drag boats to keep the motor in the rear right near the prop.

Also these guys use a type of v drive to keep the motor near the rear. But they do need a axle with a really offset diff.
