Radio Controlled Rocket Glider Kits
Servos in place on the wing
Glue the spar using foam safe CA+ into the slot, then tape over with the blenderm tape.
Install the rail button parts onto each blind nut.
Center the wing and then glue in place using foam safe CA+
Glue in each control horn into each surface in the pre-made holes making sure the pushrod is closest to the body tube.
Glue in the motor mount.
Insert the blind nut for each rail button
Glue in the skid in front of each rail button using CA
Glue the vertical tail, make sure it is perpendicular and straight
Join Tubes with arrows aligned

Put a small amount of glue on the top of the surface where the control horn prongs stick through, this will lock them in place.
Put velcro in the bottom of the shoulder of the nose cone for the battery
Glue the wing at the pre-glued joint using foam safe CA+
Glue on the two wintips with the short part facing down.
Servo wire routed through body tube to front, and taped over
Body tube joined and wing slot cut. Be sure to install both rail buttons on the marks on the bottom of the tube at this time before installing the wing!
Insert a pushrod into each control horn, one from each side.
Welcome to the world of rocket boosted radio control gliders. This is not a model for a novice RC pilot, but anyone who is comfortable with RC flying of a medium speed model should be fine. Read through the instructions, look at the photos and be sure you understand the step before commiting to cutting or glue.
Hypersonic III Rocket glider instructions
Identify all pieces, the kit should contain:
1 wing taped together
1 Nose Cone
1 wing spar(carbon fiber)
1 vertical stabilizer
2 control horns
2 Centering rings
2 Body Tubes
Velcro(for battery and rx/bec attachment)
2 Rail buttons with t nuts/screws or 1 Launch lug
2 landing skids
3M blenderm tape
Notes before starting:
Reference to CA+ means foam safe CA+, normal CA+ will melt the foam! Normally you need to use accelerator to get the CA to set on the foam since there is nothing for it to soak into and activate.
You may use 220-320 grit sandpaper and a sanding block to slightly round the edges of the foam if you prefer that look. It will not markedly impact the flight performance either way. Be very careful and use a light touch, it is very easy to catch the foam on the edge of the paper and tear the foam. Do any sanding before assembly.
Epoxy is not needed in this model. Weight is critical and the model is designed for the thrust and flight loads. Weight in the rear end is bad and will require additional weight in the front of the model.
The basic construction is now complete.
Note: Your radio needs to be configured for Delta mixing, this means that the servo arms will move the same direction during elevator stick movement and opposite for aileron stick movement. Connect your servos to the receiver one in the aileron connection and one on the elevator connection and apply power. Use a servo arm at least 9/16” long and with holes small enough that there won’t be slop with the pushrod wire when installed. I use the hole furthest out on the servo arm, to maximize movement. On some servos there are a long two-ended servo arm, you can trim off one end if needed to get sufficient length. Zero out any trim settings on the transmitter. The model once the motor has burned out is nose heavy and flying wings lose pitch authority when nose heavy so you want as much up elevator travel for trim/flare as possible.
Flying: See the Instruction/Information link at the top for flying instructions. Be ready on the first few flights to keep the model straight till you have the trims set perfectly for boost and glide.
Battery mounted in nose cone shoulder
Make a hole in the front and rear rail button marks "RB" using a tool to fit the blind nut for each rail button.
Mark the holes for each skid, make sure the skid won't hit the rail button.

Hypersonic III Rocket Glider Kit
The Hypersonic III RC Rocket glider kit is modeled after the X-15-3 Delta configuration propsed in the 1960's to allow the design to exceed mach 7. It features a clipped delta wing, and special 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" white tubing for the body and depron wing and tail surfaces. Construction is very simple and takes about an hour and a half. The only hard part on this model is cutting the slot for the wing after you assemble the body tubes, however the slot locations are pre-marked for you. You will need two 10 gram type servos, two 16"-18" servo extensions, a receiver, and a small 500mah single cell lipo battery. You will need a transmitter with delta or elevon mixing.
Please refer to the notes on items needed for completion and flying, then read the instructions completely before starting assembly. The assembly photos are for general reference but may not include every step in the instructions. If you want hardcopy to work from, all you have to do is click/drag/select and copy all of the text below the photos, open word and paste with "keep original format" and it looks exactly like it does online then you can print it.
CG location for rocket flight: 13.25" measured from the rear end of the main body tube assembly, this should be approx 1/4" behind the joint between the two body tubes.
Mount with centering rings installed
Insert the wing into the slot.
