Future Fuels
Thanks to environmental regulations, court challenges and economic realities, an unleaded replacement for avgas is definitely on the horizon, but it’s still a distant horizon. Meanwhile, we still have 100LL, which remains widely available. By Paul Bertorelli.
Modern Exterior Aircraft Lighting
It’s your best way of letting other making your presence known to other pilots, so your exterior lighting system deserves careful thought and planning early on in the build process. Fortunately, there are choices for every plane and budget.
Firewall Forward: Electrical Systems, Part 1
Don’t be intimidated by the prospect of wiring—plenty of homebuilders didn’t know how to do it when they started their projects. Get yourself the right tools, then jump in and start learning. Dave Prizio outlines the basics.
Ask the DAR
What paperwork is necessary when a new owner makes an engine change? If floats are replaced with conventional gear, what does the change in gross weight mean for a plane's LSA status?

Firewall Forward: Cowls, Baffles and Intake Air
How to keep your engine’s carburetor or fuel-injection system breathing right.
