Titan II Dynasaor
 
Had the final two flights today on my Titan II Dynasoar stack, both were perfect, here's the flight video from yesterday. Glider is 32" long and weighs 8 oz, full stack is 8" diameter by 9' tall and made out of 2mm and 6mm depron and weighs 80 ounces with glider ready to fly on an H motor, boosts to around 400' and then ejects the glider which is RC. Got some great video and still shots which is what I was hoping to get. Retiring it now while it is still in one piece after 2 years and more than 10 successful flights.

Frank, you do some really amazing stuff! I always love your videos.

I saw this beast fly live-in-person on Saturday. Amazing!

Frank also launched a big Atlas missile.

You know how to use the wind to your advantage--great model *and* piloting! With Blue Thunder propellant motors (*if* "H" motors using it are made), you could even simulate the Titan II's transparent exhaust plume. Also:

Have you considered a Thor-ASSET or a Winged Gemini (it was to be Titan II-launched: http://web.archive.org/web/20090607...ft/winemini.htm ) R/C model (see: http://www.google.com/search?q=Thor...0.MGtg6pD2 7So )? The ASSET (Aerothermodynamic Elastic Structural Systems Environmental Tests) re-entry gliders were Dyna-Soar (or Winged Gemini) test vehicles, and they were boosted by single-stage Thor and two-stage Thor-Delta (with the skinny, modified Vanguard second stage) launch vehicles.

Here are some great shots from Gary Goncher, that I also shared on the NAR facebook page.

FWIW, I want to point out that the fins are stock. It's been a while since I had read up on the Dynosoar so I took a look at the Wikipedia article on it which clearly shows the fins in its illustration.

Often when scaling rockets with active stabilization (via gimballed motors) modelers need to add fins, but in this case, it's completely legitimate.

This is a very well done project.

Yes--the Titan II/X-20 suborbital test configuration and the earlier Titan I-boosted configuration both had large trapezoidal fins on the first stage. The Titan IIIC-boosted orbital version had no fins (at least not in any of the illustrations that I've seen of it). I guess that in the pitch plane, either the Stage 0 solid propellant motors (they were designated "Stage 0" to avoid confusion because the Titan IIIA and IIIB had no solid motors), along with the core first stage, provided enough aerodynamic force to overcome that of the X-20's wings, or the solid motors' thrust vector control system provided enough control authority (in pitch *and* yaw) to overcome the "head-end" forces of the X-20's wings and vertical stabilizers.

Rather than start a new thread, I thought this would be a good one in which to mention the new release from Boyce: https://boyceaerospacehobbies.com/p...it-1-73rd-scale

Mine is on the way! Can't wait to build it!
