Radio Controlled Rocket Glider Kits
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 II Rocket glider instructions
Identify all pieces, the kit should contain:
1 wing taped together
2 wing spars(carbon fiber)
1 vertical stabilizer
1 control surface
1 control horn
1 photo printed canopy
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 Note, my prototype needed a small amount of down trim on boost. Be ready on the first few flights to keep the model straight till you have the trims set perfectly for boost and glide.
Hypersonic II Rocket Glider Kit
The Hypersonic II 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 mid mounted 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, pre-printed cardstock canopy, 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 12"-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: right at the joint between the two body tubes, ~13 1/2" ahead of the rear body tube.
