[quote=Topaz;24301]Looking through my own set right now, I think you could lose a few pounds by:

• Doing without the little windshield, pilot fairing, and cowling. It all appears to be cosmetic - near as I can tell, all of it is non-structural. Definitely check me on that, though.
• The plans call out "wheelbarrow tires" and, I assume, wheels. Very heavy. Go to Aircraft Spruce and get real ultralight wheels and tires. You'll pay more for them, but probably lose 2-3 pounds each, or more.

Note that all of the things I mentioned are at the front of the plane, however. You could remove them only to the degree that the center of gravity remains within the specified limits with you aboard and using the engine you choose. Your engine choice will affect the weight the most, but again, you have to make sure the airplane balances at the right spot, no matter what engine you choose. Your choices, therefore, are a bit limited.

Good suggestions, Topaz. The Builder's manual actually states exactly what you say here: the cowling, cockpit fairing & windscreen are strictly cosmetic, not structural.

I've already opted for Azusalight wheels. Now to find the right size tundra-type tire.
