I wanted to do something similar to the old Estes USS Atlantis, which was a long star trek themed rocket, I needed to keep weight in the rear at a minimum for a rocket glider so used one warp pod instead of two, and then did shapes as star-trekkie as I could, modified the nose to have the deflector dish inset.

35" long, 22" wingspan, 2.6" diameter, uses MPF for wings and depron for the vertical support with a carbon rod for strength. Weight is 12 oz rtf , Flights were perfect right off the drawing board with no trim changes,

Here are three projects I did in parallel, the UFO Invader was themed on the old Centuri rocket kit, the Fireball XL-5 was as close as I could get while still having a decent glider and the Maurader is a top intake cruise missile styled model. All are around 10.5-12.5 oz rtf, use 2.6" tubing, and MPF and are 20" wingspans and 32-33" long.

I did a torture test yesterday, 10 flights on E-20PW rocket motors, these give about a 150mph boost speed, and unless the glider is perfectly trimmed it would be a disaster since there is no time to steer I recommend the E-6 longburn motors since you get the same altitude at a bit less per flight cost and you have plenty of time to steer on the way up.

I decided to work up a new kit version of my SR-71 profile I did a few years ago, to use a split tube above and below the fuse/wing profile and do tubes for the nacelles but just do them on the top to save tail weight. The SR-71 has very little of the nacelle below the wing line in any case. I worked with a local rc club mate to do some 3-d printed intake cones that have flow through, and some top and bottom pieces for the cockpit and battery access in the front. I've done three versions, an SR-71 version, an A-12 single cockpit CIA version where I used sharpie pen to make the wing corrugations and panel lines before spraying silver, and a one off version of a YF-12 interceptor. On the YF-12 instead of splitting the tube I slotted it so that the normal nose cone would fit into the tube, because of this the chines are a bit shorter than scale.

The first two kit runs are sold. 39" long, 21.5" wingspan, 13.25 oz rtf using a 24mm E-6 rocket motor. This kit is about 15% larger than the old hobbylab kit, with 33% more wing area at about the same flight weight.

Some videos, the last video was an early prototype without markings, but that I was able to do two carrier type arrestor hook landings with
