Default bent chassis plate

Hi all,

due to the irresponsible fellow at my track who turned on his transmitter after informing him , this has happened.

I`ve tried knocking it, heating it then hammering it, but it still won`t budge.

does anyone know of a better way?

thanks in advance.

Solution: Make the guy pay for a new chasis. Or if it's alluminum..........try heating it with a torch and banging it just a little......

You really need to buy a new chassis. Especially with it being bent that much. When aluminum bends, it changes on a molecular level and becomes softer. You can bend it back and it will look straight, but it takes a much smaller force to bend it again.

If you really don't have the money to buy a new chassis, then you could bend it back. I have done it myself many times. The easiest way to straighten yours would be to use a vise and 2 rods. 3/8 or 1/2 round wood dowels would be ideal, but you can use almost anything. Put it in the vise like the following diagram. The straight line is the bent part of the chassis
o___o
O

When you squeeze the vise, the chassis will gradually bend back to straight. Don't try and go too fast. Take your time and you should be able to get it pretty flat. When you start using the chassis, you need to check the chassis after every few runs to make sure its still flat. Good luck

just replace the chassis and notch it up to experience. install a failsafe when racing where there is no radio impound.

even after straightening the chassis it still wont be straight(tweaked).
it looks like the bulkheads mount onto the bent area which is going to cause havoc in setup. the car may drive unpredictably due to the incorrect geometry relating to the chassis

Okay here's a kinda hack sketch. Just go slowly and work a little bit at a time. I was able to get a fairly bent chassis almost perfectly flat. I doesn't stay that way if you start hitting stuff, but at least you can run.

Thanks for all your help guys.

have got a clearer picture of what to do with the vice already.

i`ll try straightening it up first till i can afford a new chassis.

I won`t get him to pay for a new chassis. no point as he`ll deny like he did. guess it`s part of the hobby.

Thanks again guys, really appreciate it.

You might need to just clamp the very tip of the chassis into the vise and pull the other end. You can also use the same method with the vise jaws open a bit and just use them as a brace while you bend. Just try different things to get fulcrum where you want to straighten. Good luck.
