Looking at the Eureka plans .pdf file on their website) it looks like they've omitted the air brakes/spoilers. Are you going to go with extending the leading edge of the flaps forward of the hinge line to act as air brakes like the original?

Also, I read that you're going with mechanical retracts. Robart 609? 85-degree or 90-degree?

Your build is a real gift to those considering this kit. Thanks for sharing and for answering questions.
