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.
Identify all pieces, the kit should contain:
1 wing taped together
2 wing spars(carbon fiber)
1 Vertical Stabilizers
1 horizontal stab assembly.
2 long Foam wing reinforcing strips
2 medium Foam horizontal tail reinforcing strips
2 short foam motor mount reinforcing strips
2 Body Tubes
2 ramjet intake blocks(foam/ply stacks)
2 ramjet standoffs
2 ramjet tubes
2 servo ez links.
3 3/8" wide foam strips for the conduits.
Velcro(for battery and rx/bec attachment)
2 Rail buttons/t-nuts or 1 Launch lug
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.
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. I did not use any epoxy on my model. You may use a very small mount when mounting the ramjet pods to the body tube, but it is not necessary and adds weight.
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.
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.
These kits are for the advanced rc rocket glider flyer. Wing loading and weight is higher than my other kits. If your RTF weight is near 15 oz, you can successfully boost/fly it on E-6 torkcet motors. If it is heavier, it requires it to be boosted on a faster E-12RC or E-15-PW aerotech motor, or an epoxy plugged Estes E-12-0. The landing on the ramjet pods requires more finesse on landing to avoid damage to the model. Glide times are correspondingly shorter, typically around 30 seconds. It is 45" long, 2.6" diameter, ~16 oz rtf and has a 21" wingspan. It is approximately the same size as the madcow kit but approximately 1/3 of the rtf weight. At this time I only have parts for one more kit.
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.
