Here's another fun kit I just released. It turned out that the biplane version turned out to be a bit more complicated to build and fly than I wanted but I still love this color scheme and styling, so I re-worked it.

The Iron Cross RC Rocket glider kit is based on a top secret WW1 Rocket powered mid wing monoplane interceptor. It has a graceful birdlike swept wing with scaloped trailing edges, a ww1 styled vertical stab, and an open cockpit. It comes with a plastic nose cone, 2.6″ white tubing for the body, Depron wing and 6mm depron tail surface. The wing is pre-grooved for the spar, control surfaces are pre-hinged, and the body tube is pre slotted for the vertical stab and partially slotted for the wing. Markings shown(not included) are available from Stickershock23.com 33″ long, 23″ wingspan, 10.75-11 oz rtf.(painted)

Here's a kit prototype I did themed on the Phil Kraft 1966 Das Ugly Stik, since it's a rocket glider with a tail mounted motor, I needed to have rear mounted wings for CG reasons, the first variation was a canard with kf airfoil which flew great but I built it without a kit in mind so my wingspan was too long and I had to slot the tubes for the wing/canard. A few customers really wanted a kit, so since I had to rebuild it to fit into a kit box anyway, reducing the span would make the glide shorter, so I decided to go with a staggered biplane design and get rid of the canard. This was my first biplane. With some planning the kit came out perfect with no nose weight needed. 11.5 oz, 23.5" wingspan, 32" length for my usual 24mm E-6 motors. I tried to keep the general tail and wing styling and the color scheme. On early testing I found I was getting wing flex without interwing struts which would make it hunt in pitch, I inserted two 3" wide struts and that fixed the problem. Painted with testors flat red and finished with cut vinyl decals from stickershock23.com.

My daughter had 10 minutes for a video in the morning, so I just did one flight, boost and landing were good, I did push over a bit early so it cost me about 10 or 15 seconds of glide time.
