How much dihedral are you planning on using Henk?

Get rid of most of the dihedral Henk or else it won't be effective.
You can couple rudder with the ailerons as an alternative but you really don't need the ailerons if you keep the dihedral.

Looks good, you will want to keep a bit of dihedral.. it looks better ( otherwise flat wings have that droopy, anehedral look. )It stops it flailing about the sky too when flown slowly ( or underpowered) , adds a little latteral stability too.. and it'll still look like a tomboy

Absolutely right Grunta, remember the original Kwik Fly - looked horrible! I reckon the 1" Henk has settled on is just right.

That model sounds familiar... is that the Phil Kraft designed one ?

PS: nice job on the wing Henk.

Hi Grant. Yes, that's the one. The original model had a flat wing, engine canted at 45 degrees and no canopy - it flew beautifully but was just about the ugliest model I had ever seen! Subsequent published and kitted versions (such as "old orange trash" which Kraft used in the World Championships) incorporated just enough dihedral to get rid of the droopy look, a canopy and a much neater engine installation. Although still not the most beautiful or elegant of the then current aerobatic models, it looked OK, and was a very easy model to build. I had one with a Merco 60 and it was a joy to fly.
