Of the 3 bodies styles shown which is the weakest?

[bracketracer]

When I was looking at the given body structures in my mind, I only thought of the twisting of the body left to right and not the bend of the body front to rear. No contact to the track on the NDFW side of the car is why I was thinking primarily of twist. Interesting either way. Do we have a new body style to try out now??? Thanks for the research 5Kids.

I was thinking the same way GX!

EDIT: Now that I'm at work and have time to study the results /images/boards/smilies/wink.gif, that chassis IS being twisted isn't it? You have the load applied to the left front axle hole only. I couldn't see that on my small screen at home.

Not new, I've been making them that way.

Again you have shared a ton of info with us all again. This is some really cool data I would not have thought that this would be how it turned out... But I am still the rookie learning and watching seeing how things tick....

I do have a question this is just a frame and showing how it could react correct? If the planking was added and glued would that decrease the flex as it should in theory make that bond and become one piece? The planking is on both top and bottom and creating a more rigid frame?

. I would hope it would allow less flex. I have seen guys add in foam and other material to fill and it be glued to the frame as they are trying to stiffen the frame and make it stronger and lighter....

Lots or R&D and I do appreciate your time in these forums!! Just wrapping my mind around it all....

Yes, adding like a 1/16" thick covering to the ladder frame would make it more rigid and have less deflection. You would essentially be turning it into a "T" beam type situation.... using the same material as the frame you would increase the body weight by over 30%.

If you added a covering to the bottom as well you would create an "I" beam situation which would be very rigid.... you would also add almost 50% more weight.

For comparison, here is a solid body.... It is the real winner. You would add 75% material over the ladder body, so if you can build a 0.300 ounce bare ladder body you can build a 0.525 ounce solid body.

Winner, winner chicken dinner!!! Thats the way all mine are.

If I had built more cars that were fast, I would have a better perspective. As always, everything is part of a trade-off. Most, but not all, of my few fast cars have had solid bodies out of pine (and they take the least time to make !). I tend to think that the hollowed bodies with 1/64" covers have a pretty good weight/performance ratio and as long as you can accurately drill them after they are produced. I think if you worked hard at any style you can make it fast - the proof is out there.

I'm with you there QT. To this date this is the only type I've built. I won't say this will hold true for the future though. We'll see.
