Here I would like to introduce my scratch built FPV40 built using a KFM4 Aerofoil. http://en.wikipedia.org/wiki/Kline%E2%80%93Fogleman_airfoil (http://en.wikipedia.org/wiki/Kline%E2%80%93Fogleman_airfoil)
Let's see.. Its built from 2 sheets of depron, 2 layers make up the main body and 1 layer top and bottom making the KFM step. It has 2 6mm strips 750mm for additional strength, not sure if its needed or not.. I've taped the majority of it now apart from the centre section. This is where the battery, mobius, vector etc are mounted. Not sure what to do about the centre section, might build up a cover to go over the Vector.

This was a great flight and the first bit of good weather we've had in a while: https://youtu.be/7ZjoVcxmPi0 (http://https//youtu.be/7ZjoVcxmPi0)
Couple more pictures
Motor is a Sunnysky 2212 1400kv with an 8x6 prop. Battery is a 3700mah 3s, needed to get the cog right.
Pretty good for flying formation with a Bixler, Vector was working overtime in places as was rather windy

This was from earlier in the week when I snuck out in my lunch hour. Wind was reasonably low so could get down nice and low, I've been trying the Vector in 3D Hold which seems to work well on this wing
