Resistance of styrene body?
 
Hi all,

I’m starting a project that I’ve had in mind for many time...I will try to make a Daf Turbo Twin II body to be used in my TRX4 Chassis (so it won’t be 100% scale, it will be a little bit wider than it should)...

My question is...how resistance to use it would be? Good enough to use it normally as a lexan body? (rolls may happen....). I’m good with some scratches and so on, but not with a complete loose....

I’ll hate to get it broken or distroyed after few drives, but I’m not looking for a shelf queen....

What’s your experience?

Thanks!!

Hiya, sorry this place is so dead these days. In answer to your question: it's as strong as you make it.

The styrene itself is pretty strong, at least in slowly-applied pressure (ie, rollovers) but it will crack if given a sharp impact (crashing into a rock head-on). It will not have the "bounce back" that Lexan has, but it has one advantage: it can be repaired much more easily than Lexan can.

In terms of designing for strength: use nice thick styrene (.060 or so) and a good weld-type adhesive (Bondene and Tenax are two well-known brand names). This type of adhesive literally makes one piece of plastic out of two, instead of holding two pieces together like cyanoacrylate "super glue". You can reinforce the corners and window pillars with a second layer of plastic on the inside and it will help immensely.

Expect to get some cracks, and dab some adhesive into them to repair them, and expect to lose mirrors and door handles and little details like that once in a while, but in general, don't be afraid to drive the truck hard. After all, if you made it, you can fix it, right?

Resistance of styrene body?
 
Thanks Mark!

I thought that the forum was more active....

I appreciate your tips and comments, I’m around 70% of the build...is not 100% scale, I need some ”licenses” to fit it in my Traxxas TRX4 chassis and also because I will do more rock crawling than kind of Dakar trails bushing at high speed...

But it doesn’t look so bad at all....









Still long way to go !

Very cool!

Are you going for a Dakar rally or Trial truck?

Very cool. It does look like it goes very fast sitting still
