Model rocket parachute template

Take a used 18mm casing, knock out the nozzle and burnt debris. Depending on the engine power A, B or C the inside diameter of the casing may differ. Try sliding a 13mm engine inside the casing. Sand the inside of the 18mm casing until the 13mm engine slides in easier. Friction fit the smaller engine in the adapter with masking tape. The same techniques could be used to fly a 18mm engine in a 24mm model.

Try fitting an A, B or C sized engine into a used D sized motor casing. I started making fins this way after building a few carded rockets. Carded rockets are made using 60 — lb. But the leading edge ends up rounded. The outside and trailing edges will be square. Layer 1 lb. Save cereal or cracker boxes. Sand the printed side of the cardboard use grit to remove some of the ink and gloss finish. This will help the glue adhere better. Design your fin and cut out a template.

Trace it onto the lb. Flip it over, matching up the leading edge. Use the Rocket Motor Guide to determine the right motors to use in your rocket. Compare Motors. View combined time-thrust curves and specifications for staged and clustered motors.

Contact Us The instructions are lengthy and very good. This is listed as a skill level 4 kit and I believe it. A couple of the steps were a little confusing to me, but I emailed Sunward and they replied within 1 day.

One of the steps in question was the use of the paper template. I wanted to make sure that it was the skin of the pyramid. The other question was about how much nose weight to use. The instructions tell you to add extra nose weight for E motors, but it does not tell you how much. I added as much nose weight as I could fit under the forward closure.

The instructions specify white glue for working the paper template. I think that is critical to getting a smooth finish. Be sure to brush on the white glue lightly so the paper does not wrinkle. Finishing: The pyramid is very easy to finish. You just paint the paper template.

I did not use any primer and the finish is a nice bright yellow. Flight: Prepping for the flight can be a little tricky. You have to roll up the parachute tightly and fit in the motor mount. The streamer for the motor mount is also tucked next to the motor tube.

Be sure not to wrap the parachute or the streamer around the motor tube as they may not open up if you do that. The flight was straight and true.

The pyramid boosted well on the D It had a little spin after burn out and looked cool doing it. It should really fly well on an F12 or E Recovery: The recovery was nice and easy. The pyramid uses The ejection of recovery device through the rear of a model.

The motor mount and parachute are ejected out the rear.
