These Mike Arnold movies are fantastic indeed.

I was blown away by his method of making thin
sandwich wing skin panels, starting with the
Rutan technique and then taking it one step
further. Basically it's very simple, but yet I
had never heard of it, or thought of it.

The build quality of his AR-5 looks very, very
good. And his patience in shaping that fuselage plug is amazing.

Very recommended!
