I like Doug's ideas, except make the slats automatically retract and extend like the
Pegazair.
Under a certain speed they pop out and over that speed they retract, automagically

I believe its similar to a spring loaded system. I may be wrong but I think this is like a Chris Heinz design done long ago. Reading below it may even be older than that!
This is a Peg in Chapter 691 built by Will Fox. Picture credits to Will.
I fell in love with this unique version of Will's Peg although the slats are the factory design. To keep it RV related, Will did all the EAA inspections on our RV-12 build and has done many other RV's and other aircraft as well. Notice the hand bent tungsten landing gear! An engineer and a craftsman all in one. Also note a modified RV-8 cowl...
I bought plans to the Peg (and many others - even Glastar kit #500) but in the end realized that I loved working with the metal Van's models. The well thought out process they give you to create a safe, fun, fast beautiful machine can't be beat. I'm proudly more of an assembler than a plans builder. It's ok to beat on your chest about that, we all have those things that we cherish and love doing. In the end it's probably safer that I do assembly rather than design! Computers, rivets and Jazz are my thing.
