Default RE: Whatever happened to the kits?

CrateCruncher - the laser cutting is already very simple to do, without going to those airplane kit cutters and waitting a long time/paying a high price, in case you want something a little different than the large scale warbirds.

You can easily, quickly, and cheaply have your parts cut even from old paper plans that did not come as a *.DXF file.

Laser cutting technology really has nothing unique to model aircraft, and a friend and I noticed that there are many arts and crafts shops and gift shops that do laser cutting and engraving for gifts, plates, and various ornaments.

Most will happily cut anything you want provided you bring a Corel Draw compatible file, showing the necessary parts and fitting to their stock sizes of sheets.

I scanned off some plans the parts I wanted, I also added some lightening holes as I was going to use liteply in place of balsa in certain parts, my friend then took the scans and using Corel Draw converted the Raster files to Vector files, very quick and easy.

Next we went off to one of the local malls where the shop was located and gave our order.
On the spot, they laser cut for us paper parts just for us to check it was OK, and once we approved, they said to come the next day to pick our order.

The pics show the results. The young lady who did the cutting has no idea what an RC model is, but made great parts.

So it was quick.
How about the cost? well here's an example - the undercambered ribs in the photos for example, are for a scale bipe that spans 72". I produced close to (100) ribs and the cost, including materials, came to approx. (20) U.S. Dollars.

Consider that we do not always need to laser cut 100% of the parts really, as some are very simple and few, and you'll see that a couple of hours on the PC/Laptop can yield lots of accurate quality parts, in no time, without any dust or sweat.

Most machines easily cater for raw material sheets of 400X600 mm easily covering most of what you'll need, but it is also easy to modify parts to make them up from smaller ones with "dove tail" joints that are 100% accurate, if needed.

BTW, you can easily modify parts yourself before cutting, either on the drawing with a pencil, or on the computer.

I'm sure you can find such services in the U.S. too.

It's not quite like having parts come off your printer at home, but still very easy. Has changed my approach to making parts when scratchbuilding.
