I had done a smaller version of this a year ago using 2.6 in tubing and using a trick of an oversized wing with the oversized portion painted flat black so that just the scale wing outline was mostly visible and it worked really well. I decided to do an upscale using 4 inch tubing, modifying the nose cone front block head off and turning the rear diameter a little bit to match the thinner wall tubing I'm using. are you single ply 9 mm depron for the wings and tail with 1/8 carbon spars, two in the wing and one in the vertical stabilizer. the decals are a mix of hand cut self-adhesive vinyl and some printed vinyl from sticker shock 23. This model weighs 28 and 1/2 ounces without the motor. I had five test flights I started with an f -26 then an f-25 then 2 g-38 and 1 g-40 the video shows them in reverse order. These are all composite Aeroteh motors without the ejection charge. I was super happy with how stable at boosted and how slow and docile it was gliding and. landing. it's really draggy so the flight times aren't super long but it really looks the part and I'm extremely happy with the way it turned out.

I decided to do a 150% upscale of my avro arrow, I was able to use 3" tubing, and a better nose profile cone, using single ply 9mm depron with a little carbon reinforcement and get a 37" wingspan version that comes in at 27.4 oz rtf using a 32mm G-12 8 second burn rocket motor
Accents and panel lines with sharpie pen and self adhesive vinyl. Roundels, and lettering from Stickershock23. Sims show a boost altitude of around 600'. Goal was trying to keep weight really light, using a profile of the intakes and working with a nose cone and tubing I could easily get. About 1:17 scale. This uses elevon only since I don't need rudder for boost and glide, running off a single 500mah 1s battery, very lightweight setup.

I just finished this up, an RC Avro Arrow RC rocket glider. The nose profile is not correct, but it was designed to use a an available inexpensive part to fit the tubing I use. 33.5" long, 2" diameter, 23.5" wingspan. It's a nice flyer, 10.5 oz rtf with about a 6 oz wing loading. The body tube is cut at an angle at the rear and the motor tube is mounted right under the top of the tube inset about 1.75" to help cg. Depron wing and tail with a single cross 3mm spar and side plates to mimick the intake and tail cones. Black on the nose was painted, the rest is vinyl self adhesive trim hand cut. It's not scale due to the profile intakes and using a tube for the body/nose, but I think it captures the look of this outstanding aircraft.

Hope you like it

Here is one I decided to kit, it's one of the proposed X-15-3 Delta configurations designed to get the X-15 above Mach 7 and for extended periods. I was not able to extend the strakes all the way forward for CG/weight reasons, but it looks pretty good, is a nice big size and flies really well on long burn 24mm rocket motors. RC Rocket glider kit is modeled after the proposed X-15 modification to allow sustained flight above Mach 6.7. It features a clipped delta wing, diamond shaped wingtips. It has a light wing loading giving it a very nice glide and easy/stable boost. It comes with a plastic nose cone, 2.6″ white tubing for the body and 9mm depron wing and tail surfaces. All Foam surfaces are pre-beveled. Elevons are pre-hinged, the rail buttons are pre-installed and the body tube is pre-slotted for the wing and tail. The wing spar is pre-grooved for the spar. Length 37″, wingspan 20″, weight rtf 11.7-12.25 oz. I finished mine in white because at high speeds it would have most likely needed the ablative covering like the high speed drop tank X-15-2 version. It also saved me a half ounce of weight.

I have built this that I drew up many years ago in several versions, 6mm depron single ply with rocket in the rear, with tractor motor up front and air start rocket in the rear, in a doubled KF airfoil as both tail electric pusher and rocket glider(to stiffen the wings), I decided to build another one purely for rocket glider using some 9mm depron I have, allowing me to keep to single ply. I did a pseudo winter camo black/white eastern front scheme for fun. The problem with tail mounted motors in ME-163's are the moment arm of the tail to the CG is longer than to the nose so getting balance is a challenge. It came out a bit heavier than I wanted but still flies nice and is very docile on boost. As with any wing with CG shift as the motor burns out, the elevons don't have a lot of leverage in nose heavy condition and they can run out of flare on landing, but this one is pretty well balanced, not twitchy on boost and still nice to land.

25" long, 37" wingspan, 15.5 oz ready to fly using a 24mm longburn E-6 motor. I flew on E-12 motors but the boost is just faster but doesn't go quite as high.

Glide isn't terribly long, but this one was just for fun and looks good.

I was asked by several folks to see if I could bring back my profile Dyna-soar kit I used to do as a rocket glider, due to the loss of true depron 6mm, the depron aero wasn't stiff enough to continue the kit and MPF was not uniform or stiff enough either. I was able to buy a supply of 9mm depron when rcfoam went out of business, so for a limited time I'm redoing the kit, calling it the Lifting Body, even though this is more of a small winged boosted glider than a true lifting body, it still fits the definition. Profile gets you maximium wing area, the 9mm is heavier but is definitely robust. Available from dynasoarrocketry.com

Here's a pic and video, 21" wingspan, 31" length, 14 oz rtf using a 24mm E-6 rocket motor. This is the same size as on the cover photo on top of the Titan II stack, but without a full fuse to make kitting/construction and flight times better. It can also be had with two other fuse/wingtip profiles to simulate X-24 or HL-10 styles

Here's another I decided to kit. I figured my Iron Cross (Das Ugly stik) themed rocket glider needed a good guy to keep him in check. So I was inspired by the P-26 peashooter and inter-war us army air corps color schemes and here is the final product. 2.6" diameter, 34" long, 23" winspan and 11 oz rtf using a 24mm E-6 long burn motor.

Here are three new models that I did a while back but I decided to kit recently. First is the Mig 10 based roughly on the centuri mach 10 rocket glider and a mig-15, second is the UFO invader based on the old centuri UFO invader rocket kit but with the wing upsized for glide, and lastly the yf12 which was an interceptor prototype built for the u.s. air Force based on the SR-71 and A12 platforms used to do high-speed missile launch testing and then later by NASA. are designed for the excellent long burn 24 mm e6 rocket motor available online at dynasoarrocketry. com.

I was watching The Man in the High Castle season 3 and that German SST design really got to me with the little forward and rear canards, the top mounted forward fin, and the paint scheme, so last night I designed and put this together and then this morning I painted and hand cut the vinyl trim and applied and it turned out pretty nice. I took a wing design I use on some of my kits, moved it forward to allow for the angle cut rear tube, and then trimmed the forward section down to be a bit more concorde like and reduce forward area to allow my CG to be the right place without having to add nose weight.

It's got a 23 inch wingspan, is 34 in Long, and11 oz rtf.

Disclaimer the swastikas are not any political statement they're just part of the paint scheme.

Here is another prototype for a custom kit, based on the old Estes Space Transporter America, which was a shuttle style rocket and had very small wings, so wings were upscaled, adjusted for CG, and upscaled to BT-80 size. The video shows the second flight first, the first flight is second and I over-adjusted on boost on this flight, and then adjusted the boost trim for the second flight which is a lot smoother. 38" long, 23" wingspan, 11 oz rtf using a 24mm E-6 long burn rocket motor.

Here is the prototype for a custom kit I made for a customer, 34" long, 26" wingspan, 2" diameter, 10.5 oz rtf, Based on the Jonny Quest Dragonfly III, I lengthened the wing root and moved the wing/bottom scoop forward to have a reasonable CG, flew like a champ. Plenty of authority to flare and plop down on the grass and no issue with damage to the scoop. Sharpie fine line marker for panel lines, the canards are .03 styrene glued into slots in the nose cone I made with a dremel wheel, and the cockpit is shaped depron foam glued to the cone. Windows/glare shield is hand cut self adhesive vinyl. Elevon control and 24mm E-6 long burn rocket motor for boost.

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.

I always thought the Centuri Skylab rocket from the early 70's was neat but never had one. Being left alone for the weekend my mindsim got the better of me and decided to do an RC rocket glider themed version.

I sat down and did some mass balancing Sims to convince myself weight and dimensions would work and the location if the wing and lateral stability, then looked in my parts drawer. I had some 2" tubing and 2.6". I picked up a bt20 nose cone pack and two white motor tubes for the tail thruster.

I thought styrofam coffee cups might work for the transition and nose and lo and behold the base of the cups were 2". I also found some small paper cups and they nested in the base of the foam cups to extend the nose. I doubled the foam cups for support and used a Depron disk in between them for stiffness and glued a coupler through the base for a shoulder. I doubled the cups for strength.

I'm using an 11" chord Depron wing with two carbon spars. Glide tests are done and it is looking good. I picked up some gold monokote trim for the wing/solar panels because I think it will look better than silver. It's 43" long and 27.5" span and 7.25 oz dry, rtf should be right around 12.5 oz , no nose weight was required. the RX and battery are mounted in the transition section.

I picked up some aluminum tube for rail button standoffs because the nose diameter is larger than the rear by 1/2". I put some skids on the bottom to make it level with the nose when landing.

Got the stickershock decals to finish off the skylab RC RG and got in some test flights today, was a bit more windy than I wanted and I had to keep the nose down into the headwind to keep it from balooning but overall not bad.

One of my customers did this and it turned out pretty well. He sent some parts and here is my flight.

Dynasoar Rocketry Stratodart X Night Flight (1 min 36 sec)

The parts to do your own version and what I used are below:

Small gauge wire to make the jumpers to solder to the strips and connect + and – terminals from all the strips to each other. The strips can be connected from any set of pads since they are in parallel.

Red jst connector to fit the battery.



LED Strip Light SMD 3528 Flexible Tape 300led DC12V indoor outdoor lighting rope 5 meter length



Plan battery size, count your diides, current draw is 1 amp per 150 diodes(what I used), so with a 180mah battery using about 80 % of capacity to be safe would give 8 minutes, plenty long for pad wait, flight plus recovery.

I simply applied light strips to wing and fuse to make it easy to tell the difference between bottom and top and give light on the tail. I then used clear packing tape over the lights to protect them and hold them down.

On my stratodart I needed just a few grams of nose weight to rebalance. I left the 1s battery installed for receiver power and placed the small 3s battery for lights on the cg via a hatch. Battery weighs 19 grams so my starting weight was 11.6 oz without lights, with lights 12.2 oz, with 3s batt for night flight 12.9 oz. The stratodart has the most wing area and is able to carry the weight better.

For night flying, more is not necessarily better, you can blow out your night vision.

Here is my stratodart that I built using these parts.

Here is an upscale of an old Estes kit. The original was a free flight glider and so to keep it stable on boost it swung the wing parallel to the fuse to move the CP rearward, and used a pop pod with extra fins that ejected at apogee to release the wing and put the glide CG back where it needed to be. I thought about doing one for a while, and did several simulations with wing folded and without.

With the wing folded and with a pop pod yielded about 75 more feet in altidude and about 1.5 ounce lighter glide weight, but at the cost of having to find the pod, I fly at a field that does not allow ejection of hot material from rocket gliders and the field is surrounded by tall crops.

With the wing folded but not using a pop pod, you also move the CP back, but then would need to put in some roll onto the elevons to counter assymetric drag, and add in the swing/release mechanism and you need to use a faster burning motor to be self stable, this yields about the same boost/glide weight, but with an optimized CG placement for less up trim required for glide and a bit more altitude.

With the wing fixed and steering on the way up yields a slightly reduced altitude but not as much as you think due to the slower burn motor/reduced speed/drag and a slightly shorter glide at the benefit of simplicity. That's the route I chose.

It's a 2.1" diameter, 28" wingspan, 11.4 ounce rtf model with a 10.2 ounce glide weight and about 13 ounce/sq foot wing loading with a .79sq foot wing, it doesn't glide that bad given the small wing area. Wing is 6mm depron reinforced with a .125 carbon spar, as is the horizontal stab and it uses just elevons for roll/pitch control.
