I had a break in the terrible weather and got two maiden flights in of the X-24A and X-20 style profile lifting bodies I did based on the HL-10 wing...really easy to fly.

Dynasoar Rocketry Lifting body style RC Rocket Gliders (2 min 12 sec)

Went back to this design last night. it's based on the old Centuri mach 10 which used an angled tail and an offset motor and ejected a nose weight for glide.
My previous version used a center mounted wing and no angled horizontal stab and did not eject anything. For this version, I rolled a 2mm depron skin over a 4" body tube double thick using 3m-77 contact cement. I then mounted it to a wing, the vertical tail slots through the tube put a 1" keel on the bottom to stiffen the tube and mount my rail buttons on. it will also protect the servo arms from landing damage. I made a cockpit from photo paper . AUW empty is 7 oz, with radio and rocket motor is 11 oz rtf,.

The tube is completely flow through
24" long, 32" wingspan, 4.5" tube, wing loading a bit over 5 oz/sq foot.

I've moved my plans page to my own web site now so I only have one place to manage things.

You can go to www.dynasoarrocketry.com, There is a plans link at the top. If you look under the Instructions link at the top there is more information on construction and links to some of the recommended components for rocket flight and finishing. If you go to the "converting to electric flight" link at the top it covers components if you are building as a pusher parkjet.

Here is a link to my youtube videos which cover many of my builds:

Here is a great wing CG calculator I've used for some of my odd wing shapes.
