Foamy Season is here - Milling Depron Foam -> A How To

[Matchless]

Drag to weight ratio is where it makes a difference. Put a 10 square inch plate behind both airplanes you described and time them on a 100ft drop. You'll then see a measurable difference. No 100ft ceilings in most of our flying sites, but the effects don't change.

Hey guys - I'm an "EPP Only" guy (cept for my new Micro 4-Site!) so I've been experimenting with milling in EPP. In looking for places to post my results - I stumbled on this thread. Let me know what you think of how I did it - and the results in the actual plane.

The how is on my blog HERE.

Drill the hole to fit the brass tubing you'll glue into place in a moment. Next up, I glued in a short piece of 3/8" brass tubing. Diameter is not terribly important, but your router bit needs to fit inside. Glue the piece so that 3-4mm sticks out of the plexiglass. Make sure to glue it from the topside. You don't want the glue fillet on the 'working' side. Finally, screw the modified router base on to your Dremel. Why on earth did you add this plexiglass base and tube? The plexiglass allows you to router out larger areas, and the tube allows the router to follow a pattern.

what router bit is that?

I believe this is the bit I used.

Its foam board with paper on both sides, about 1/4 inch thick. Cuts nice and clean and the weight of the router is supported with no problem. Its available at art supply stores.
