48" Wingspan / Kline-Fogleman Airfoils
Axi 2208/34 Brushless Motor
2S 2200 LiPo (use anything that fits the balance)
10x4.7 slow fly prop
Plan (version 0.94b) : March 12, 2012 Work on the Fuselage begins! March 11, 2012
Changed the tail to an inverted V with working Ruddervators.
Much easier build... and gives full tail control. It's also MUCH sturdier.
I've always dreaded building v-tails. They are a pain to align and they are usually flimsy.
My latest change to this is quite slick if I may say so
Everything just falls into place. No fiddly measuring or complicated clamping!
Hint: Notice the sq. channel aluminum that slides into the end of the arrow shaft at the tail end in Image 1.
I am posting this BUILD to demonstrate how easy it is to build a top quality RC aircraft.
While you can go to the store and buy an 'out of the box flyer'.... there is nothing more satisfying in this sport than building and flying your own plane.
The materials and techniques that I use take advantage of modern materials/technology and afford a plane that you will be proud to own and enjoy flying. The build is relatively fast. I've gone through a lot of trial and error on this one .. and discovered quite a few techniques that will make this very easy ... If you follow Step by Step!
I have designed and built many planes. Some were very detailed.
But I now find that engineering SIMPLE designs and discovering/using readily available...Continue Reading

The idea was create something SLOOOOW... and muneverable/agile that I could enjoy flying in a small park. .... among the trees.
Seems everyone wants to go FAST. But that gets boring pretty quick.
So with this in mind.... I needed to think LIGHT (yet durable)
I knew I needed a little bit of an under camber ... but didn't want to go through cutting /hot wiring foam.
Experimenting with Kline Fogleman airfoils.... I started thinking outside of the box.
The addition of a much smaller % than suggested bottom step seems to replicate the forces that are present in a typical under cambered wing. It also seems to reduce stalling considerably. But by keeping % of chord/step small... this design still has the ability to jump into 'fast'..... with excellent response/control.
The build is VERY easy and can be assembled in a night... with overnight glue times.
