Thunderchief Rocket Glider Kit
The Thunderchief RC Rocket glider kit. This is styled after the F-105 thunderchief used in Vietnam for attack/bombing/sam supression roles. It has a light wing loading giving it a very nice glide and easy/stable boost. It comes with a plastic Interceptor nose cone, 2" white tubing for the body and depron wing and full flying tail surfaces. Construction is slightly more complicated since you have to cut the slot in the tube for the wing after you join the two body tubes. 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 manual.
CG location for rocket flight: 15.25" forward from the rear end of the body tube.
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.
Thunderchief Rocket glider instructions
Identify all pieces, the kit should contain:
1 wing taped together
1 wing spar(carbon fiber)
1 vertical stabilizer
2 horizontal stabilizers
1 tail pivot rod
1 tail pivot rataining ring
2 ez connectors
2 pushrod guides.
2 Body Tubes
2 centering rings
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 and as it gained speed arced back up vertical. Be ready on the first few flights to keep the model straight till you have the trims set perfectly for boost and glide.
