The Maxout is a series of FAC embryo endurance model designs. This is a highly developed set of designs which have very competitive performance. Mine have won 1st and 2nd place at the Raeford events. I've heard news of other folk's Maxouts winning in contests they entered as well, so it's not just me.
For those who want to build a Maxout, go to www.smallflyingarts.com to find plans for the Maxout IV.
Below you can see the finished Maxout V which I ultimately lost during one of my early morning trim fields when it drifted off the field. Best flights were over 3 minutes in dead air.
