Body Holes.

Where should I put them? I'm using a 1:10 Scale car. I have this body: http://www.rcplanet.com/HPI_Bmw_M3_Gt_Body_p/hpi7452.htm.

Has the body already been painted? if not then you can just put it on the car and make sure everything looks even, then make marks with a sharpie of where to drill the holes.

Oops. It already is. I figured I could do it after I painted it. I left the windows unpainted, so I can still see the inside while the body is on though.

You can use something that will put a mark on the inside of the body. If you chalk up the body post and then line the body up it, should make enough of a mark. You can also try a bit of chewing gum but it may be a bit messy to clean up.

Simple trick. Put a dab of peanut butter on the tips of your body posts. Line up the body over the chassis. And when you're happy with the location, let it sit down on the tops of the posts. Pull it straight up and the posts will be marked inside with the peanut butter! You could do the same with basically anything gooey that will stick inside the body for a second.

Oh wait, I forgot to say. I already have the body post holes in, did it with my dad . I meant like the holes to let out heat.

When cutting holes for cooling purposes, you want to make them inline with the cooling head. You can achieve this by drilling multiple smaller holes, or a one larger hole.

ImBroken, you paint? I would love to see some pics of your recent work.

Using a wood hole drill bit works awesome for air holes. Cuts a nice clean hole.

I'm a fan of one larger hole rather than a bunch of little holes. All those little holes will create a bunch of turbulance inside the body. That makes the moving air slightly less efficient. You want to get that air in and out as quickly as possible and a straight line is the shortest route. One big hole in the back and one big hole in the front. Most bodies are plenty strong enough to have large holes cut out of them.

That's a good idea Olds! :thumbup:

I use the score/break method for ALL of my lexan cutting, including the perimeter of the body itself. It's more time consuming to get cut out but there is ZERO cleanup which levels out the time spent.
