After doing some work on a highspeed F5D Forward Swept Wing, I decided to apply what I learned into the DLG world. I have taken my own personal blend of the Zone V2 Airfoils and Drela's Ag455 airfoil. Came up with a nice CL/CD, and what appears to be a shallow stall. It is the MOST forgiving when it comes to fine tuning the CL/CD:AoA but, once achieved it seems to have a VERY high CL/CD

Forward swept wing to help incorporate the aerodynamic advantages, and inherent stability they add. I added my own blend of 3 different foils along with twist and dihedral in the tips, almost entirely getting rid of vorticies between stall and 28 mph, then they are almost nonexistent until 100 mph. PLenty of range for a DLG. According to software it also doesn't seem to want to stall out the tips either, Thus meaning no more dropped wings when trying to stay in that thermal!

Building disadvantages are complex cores, or molding. And throwing peg interference. You will no longer be able to get the throwing Peg as far back as other wings, however I think it is definitely an advantage I would give up.

This is just a gallery to serve as a gallery For my father to check out.

This airframe was received generously as a FreeBee, However I never got a good chance to work on it as I was offered a smokin deal on the TS2 Disser to replace a DLG that I broke due to a bad build/unclear instructions.




Hey Dad, Im thinkin you will really enjoy this whole Discus Launch Glider thing. It tons of fun to just give it a nice good spin and all of a sudden be 180' high. They thermal in next to nothing and it is very easy to find thermals. I'll help you With setting and adjusting everything. Starting with Aileron position. It will be beneficial to set up multiple flight modes. By this I mean a Penetrate mode (ailerons ~2-3mm up), Best Glide (0mm of aileron, perfect airfoil), Cruise ( about 3mm down) and thermal (about 6-8mm down). You will also need a launch mode which is often somewhere between 0-3mm up aileron, mixed with an up elevator trim. This allows minimal parasitic drag from the airfoil (drag being a byproduct of ALL lift inducing surfaces) and some up elevator which allows the plane to naturally climb up at about an 80 degree angle till almost stall speed then level out.

Your gonna have a Blast with this thing! scratching can be the most fun you can have and its fun as hell to get a 3-5minute flight Which took a solid 5 minutes of work and concentration.


It has some minor Defects But nothing to hard to fix! There are two cracks in the Fuse, which a simple SINGLE...Continue Reading

Well Here it goes! I originally Started this as I wanted a mid level DLG. I had previously broken a Super mini Topsky and the guys at skip miller were kind enough to offer me a pretty darn good deal on the Tsky 2.0 Disser. However At the same time I read up on the P2 and its amazing performance for the cost and couldn't help myself. So I got pulled some strings and got a bulk deal going. Now all 6 airframes have been ordered and we will be getting them mid August! This gives me plenty of time to properly, and skillfully build My Disser, as well as fly the piss out of it! Then when my P2 Low Wing comes, I will do the same with it =]]
