Building the Apogee DLG was a educational tool to work to the next step of building something larger. Down the road I'd like to build a bagged Supra or Genie, but the next step is to build a 2m plane.

We have good participation in both 2m ALES and TD classes in my local club, so I wanted to build something to compete there as well as possibly flying at NATS, since it's only an hour away from me. I also like the idea of building something the right size that I could pull the power system out of my Radian and use it in this new plane.

I've got some spruce spars left over from a kit that was never built, so I decided to start with a wood spar wing and later build a carbon fiber capped wing.
I've already got a plane based on a modified S3014 and like the way that flies, plus it's got a bit more thickness than some of the Drela airfoils.
I like the idea of a straight spar, so I've taken the Allegro planform, increased the cord to a 10" center section, and changed the sweep to keep a straight spar at the thickest point. I expect it to weigh more than an Allegro, so I wanted the extra wing area. Troy Lewiki designed Ducks still hold their own at NATS. I found inspiration in design and construction from the Duck as well.

I like the simplicity of R/E soaring, but I'd like flaps for landing control.

I've been wanting to start cutting and bagging foam wings. I went to AMA NATS last weekend and caught some of the DLG competition. Timed a round for Ryan (rdwoebke), got a look at his home built and got some encouragement to get building. I decided starting small might be good practice.

I'd already spent a long time researching the CRRC website. I decided this first one would be an Apogee-esque model with Mountain Models DL50 building technique rather than a bagged wing. (Carbon spars and fiberglass with Minwax Polycrylic)

Finally bought a Radian about a month ago.
I'll admit this would have been a good first sailplane.
I already had hi-start experience and wanted a winch launch glider, so I was a little torn about getting one until now.

I did most of the Paul Naton mods on it, carbon tow glued to the sides and a plywood keel up the fuse/rudder joint, taped the wings, changed the incidence and CG, upgraded the prop.

Compared to what I've seen with the other guys flying stock ones in our club, it has MUCH less tendency to loop on launch.
I've got the throttle on a switch, so even with a full power launch, it tracks nearly straight where you point it.

Flying on a 1000mah 30C gets me 5 or 6 200 m ALES launches at full power.

While my Wristocrat Sr. was broken last fall, I pulled out the FIRST plane I'd ever built back in 1985, a 2 meter Buzz Waltz El Primero.

I'm not sure what's going on with the dihedral it's awfully flat. I think I even tried to bend a bit more into the 1/8" wing rods before that picture was taken.

I flew for a couple summers back then in Jr. High and had been away from the hobby until deciding to by a radio and the Writocrat kit.

1.4x scaled up version of the Top Flight Wristocrat.
s3014 airfoil, RES, 36 oz.
I kept the basic planform from the original but adjusted the dihedral and increased the tail sizing based on the spreadsheet at:

Broke the wing on launch Mid-Sept. 2012.
Repaired the wing and built a new pod and boom (golf shaft) fuse. Weight dropped to 35 oz.

Built in Sept.2011 from a mid-80's kit I picked up at a local swap meet.
