I was watching Bob’s foam wing cutting video again — available at http://www.FoamWingCutting.com — and something he said popped out at me.
When you’re looking for polystyrene foam for cutting your foam wings, there are plenty of expensive options.
But there’s also a very affordable option, if you know where to look.
Take a trip to your local home improvement store, and head straight for the insulation aisle.
First, look for the polystyrene foam insulation sheets. It’ll be more than long enough, but make sure you have the width you need for your wingspan, and the depth for the thickest part of your airfoil.
Once you’ve found the right size foam, look for the sheets with the smallest amount of regrind (that’s the little dark specks you see in the white foam). Regrind doesn’t matter in insulation but a big enough piece can cause the wire to stick and create an uneven cut when you’re cutting foam wings.
Once you’ve found a mostly-clean piece of foam, you’re good. In fact, a single sheet of foam insulation can give you wings for two or three planes.
This is yet another of Bob’s thrifty modeler tips you get when you buy his 2-hour how to cut foam wings video from http://www.FoamWingCutting.com.
Hope this has been helpful, and as always…
