I designed/built this yesterday, a simplified Buran shape, with a slightly enlarged wing, approx 1/72 scale, 18" wingspan, 21" length, 8.2. oz ready to fly using an E-6 longburn Aerotech composite rocket motor.

Believe it or not we opened stockings today and I got some servos and a receiver so I put them quickly to good use. I made a small R/C rocket glider with a 12-in disc wing, bt60 tubing and a mini bertha nose cone. 25" long, 5.25 oz rtf with d2.3 motor. Flew great, nice long glide, didn't need to touch the trims got in two flights right at sunset and then headed home to hand cut some red, black and chrome vinyl trim to finish it off. I really like disk wings.

It flew! It doesn't glide very long, but it works, it's cute, it's a viper and no one else has one

I worked on this yesterday, X-37B inspired, came out nicely, using BT-80 tubing, pnc-80BB cone and 6mm and 3mm depron for surfaces and side plates. I moved the wing back and upsized it for glide and to allow it to function like a delta and have fixed V tail which works better in general than modeling the actual X-37B layout. It goes high and fast, around 800 feet, just below the cloud deck today, fast but nice glide. it's small, 24" long, 2.6" diameter, 18.5" wingspan, about 1 sq foot of wing area, 7.6 oz ready to fly using a 24mm composite Aerotech E-6. It was very roll sensitve, I had to tone down the roll rate to 30%. Looks great in the air and on approach.

I listened to an AMA podcast with Hoot Gibson and he was working, among other things, an F-4D, I figured if it was good enough for him it was good enough for me. For some reason even though I'm fascinated by the jets of the 50's and 60's I've never built one. This is made with a 2.6" tube and cone, the new 6mm and 3mm depron being imported, 34" wingspan, 32" length, 10.5 oz ready to fly using a 24mm E-6 long burn composite motor.

This was a flight on the new Aerotech 29mm single use 8" long 17 second burn H-13 motor with a spike off the pad and 3# thrust for the remaining burn time, loaded on the pad this 6' tall glider weighed 32 oz, it was a bit sluggish on boost when going vertical so I let it angle a bit and in order to keep it overhead flew in a corkscrew over the top of myself till burnout at approx 1200 feet.

I was going through cleaning out my old plans I did back in 2007-2010 which were mostly profiles and I decided to see if I could adapt my F-107 profile to be more of a full fuse design, but use a rocket tube and nose cone to make it simpler. I had to make some concessions to scale appearance but I think it captures the look ok. Length is 36", winspan is 34", weight is 11.25 oz ready to fly using a 24mm Aerotech composite e-6 longburn motor. In this video I still had to finish the vinyl markings on the other half of the plane, but the weather was perfect for a maiden so out it went. These are the first three flights in order, flew beautifully.

I fell asleep at my workbench this afternoon and when I woke up I had apparently constructed an F-35 like r/c rocket glider.....28" long and 20" wingspan... Of course the nose isn't right because the f35 does not have a simple cone but it was the best I could do while asleep😁 the airframe as it sits right now empty weighs 5 oz, 9.5 oz rtf w motor and radio. Test flights at 6 a.m. the next morning were flawless, trims were spot on!

Here's my F-35 flight from this evening in a pretty good cross wind.

One of my customers asked if I could modify my Starship R/C rocket glider kit to have two warp engines instead of one, I originally did not do this to save tail/nose weight, but I modified my own model as proof of concept, added 1 oz to the flight weight but at 12.25 oz rtf it still flies nicely, just a bit shorter than the original version, you decide if you like the look better. 19" disk, 48" length. I'm somewhat limited to the angle of the warp engines so they don't interfere with the elevons, and I need the long nose section to counter balance the rocket motor in the tail of the rocket, I don't have the advantage of an electric prop/battery that I can put mid disk, and cg needs to be about 25% of the disk root chord. It was the best I could come up with that was star trek shape/inspired but would still fly as a tail mounted rocket glider. I used depron for the warp engines since it is much lighter than actually using even lightweight paper tubes.

I designed this on Thurs evening, based on some 2.6" tubing I had and a rounded nose cone that was pretty close to profile for a vulcan, wing is 32" span, 9mm depron, tail is 6mm depron as is the cockpit and motor details. I trimmed the rear of the tube to represent the stinger on the Vulcan, of course you can't really get the shape right without doing a builtup fuse and wing with the massive thick root, but I think it looks the part close enough. Length is 28", weight ready to fly wtih 24mm composite rocket motor is 10.2 oz, wing loading on glide is 5 oz/sq foot, so it's a floater.

A customer asked if I could modify my Starship kit to have twin warp pods instead of one, it added an ounce to the overall weight, but it still flies nice and does look a bit cooler....

I had wanted to do something themed on the classic Estes Der Red Max, a made up rocket with pseudo german markings and words that just seemed to hit a chord with people, they've done all sizes of them, and applied the markings and color scheme to many other rockets, but no-one has done an R/C rocket glider. I used the body/nose and vertical stab to simulate the original fin shape with a wing that I thought was complimentary but large enough to fly well. Cut vinyl decals from stickershock23 were outstanding and it flies quite well. 38" long, 23" wingspan, 2.6" diameter and 10.5 oz rtf. Video below:
