I'm building an RV-4 with the flaps. I think that a 40 size plane lands pretty slow (relatively speaking), and that the flaps are not necessary. I want to get used to the flaps so that I'll be familiar with them for planes that really require flaps (such as a warbird). Just being able to find the knob quickly when you're under pressure is reason enough for me to include them. Plus it only costs $30 to add them. (that's 2 servos and a y cord)
