How do you guys cut those round ventilation holes in your body?

olfa (not ofna) makes a cutter

I was thinking of just tracing a cup and using an xacto knife.

Dad, just be aware that you don't need to cut through the plastic all the way. If you get a good scribed line in the plastic it will just peel right out without cracking. The Ofna cutter helps you get the perfect circle, but you still peel out the material. I have also seen a good square-ish hole made by drilling 4 corner holes and connecting them with straight cuts at tangents to the holes. It makes a nice square with rounded corners. Chances are someone at any given race will have an Ofna cutter if you ask around.

cant you just use a hole saw???
Round vent holes in body - SixVi6-Camaro - 09-04-2005
Yes.. I use hole saws to cut the holes in my bodies all the time. If not I simply use a compas and scribe a good deep circle into the body and then literally crack the round hole out.

So as long as there is a cut you can peel the lexan back and it will follow the cut?

A pattern of smaller holes with a body post reamer also works well without reducing the strength of the body as much.

Yes if you score the lexan real well and start to tear it, the tear will follow the score you made. Its kinda nerve racking to do at first so a good way to test it would be to save a couple scraps of lexan off the next body and score and break it.

And if you bash in a woodchip pile it helps keep big chucks on the outside of the body. Don't ask me how I know......
Sorry about the Ofna Olfa mixup, and I even own one!! Olfa, that is.

I trace something round on the windshield, drill a hole in the center of the trace, then cut on the traced line with lexan scissors.
How many times can you say "trace" in a sentence! lol.

who needs vents holes, the engine doesnt warm up as fast if you have vent holes

Vent holes come in nice if your marshalling. BTW I'm wearing gloves next time I marshall..
Round vent holes in body - Tex - 09-05-2005
I don't want you picking my RC up by the vent holes in the body. You may get yelled at from the drivers stand. It may be different with on-road cars because they are lighter. My 10lb off road cars don't like that
Round vent holes in body - RCDad - 09-05-2005
Yeah, with on-road it's tough, not much to pick the car up by and the bottom is hot as hell. My Super Nitro can be picked up by the wing now.
Round vent holes in body - Tex - 09-05-2005
yeah I guess it makes alot of sense to use the holes in on-road mashalling being that they have no bumpers or skids.
Round vent holes in body - RCDad - 09-05-2005
I'd like to get some rubber edging to go around the cuts but here is my body now.

Do I see an illegal cvec pipe sticking out from under that body
Round vent holes in body - RCDad - 09-05-2005
The CVEC pipe is illegal?
Round vent holes in body - Tex - 09-05-2005
I don't think anyone will give ya stink about it unless you start kickin all their asses...lol
but, yeah, they are technically illegal, for bigger races anyway.
Round vent holes in body - SixVi6-Camaro - 09-05-2005
yup.. I believe there are rules on stinger (exhaust pipe) size, only one is allowed on the pipe, and no moving parts in any exhaust system. Like Tex said tracks won't care unless you are at a big race of you are winning A-mains and somebody decideds to complain about it.
Round vent holes in body - RCDad - 09-06-2005
Technically I won't be able to race this car in the a-mains anyway because of it's size. I'll have to start racing the NTC3. By then my driving skills should be much better though.
Round vent holes in body - cemeb4dk - 09-06-2005
Looks nice, you dont have much lexan between your 2 vent holes, I hope that doesnt become a weak point for the lexan and rip. Keep it shiney side down and you should be ok.
Round vent holes in body - DAVEC-NITRO-RS4 - 09-06-2005
Shiney side UP, rubber side down.
Round vent holes in body - Tex - 09-06-2005
with George it's the other way around....lol
GO GEORGE!!!!
