Default 1/8 brass tube chassis-will it hold up?

Im thinking about soldering together a top fuel drag chassis made of 1/32 brass tube. i know how to make the solder joints strong enough, but will it be able to hold up to VXL/7-cells? i would also use a tube bender, so i would be able to make nice bends.

that would be a tough one.. to make the chassis light enough the tubing would need to be thin.. thus weaking the structure.. Might be intrested to try... i would not try and really race a seaons with it. will definatly be heavy...

that's ok, there's not really anywhere to race around where i live. just thought it wold be a fun project. and its not really 1/32, i think its like 1/8 or 3/16. don't know why i said 1/32, that would be really tiny tube. and im not sure how thin the tube is, i would just be getting whatever they have at my LHS

what scale are you going for?
K&S makes thin walled brass tube. If you're going to bend it, anneal it first, and fill the tubes with sand or a tight wound spring so it doesn't cave in on the inner radius of the bend.
Electrical solder could be OK for a smaller scale, if you're going large, use the trusty oxy torch, and silver solder it. You can always clean up your beads with the dremel (ball shaped burr)
Mine is 3/8" K&S tubing.
Whole chassis (empty) = @1600grams not bad for a 7 footer.

My LHS has alot of thin-walled brass tube, not sure which brand and they have a set of abot 5 different sizes of those springs for bending. I mentioned I would use some kind of tube bender in the first post. And I wold probably make it 1/10 to 1/8 scale.

The brass tubeing will work but you will need silver solder or staybrite silver solder. Regular solder is not strong enough.[8D]

i have a bit of experence in this department. try to get 1/4" tubing, it is light but very strong. remember to brace and reinforce. http://www.youtube.com/watch?v=40px_zcCMCg& here is a car i built, its about 20" long, 4" wide and 7" high. one of the strongest brass cars i have ever built.
