The Yellowjacket model rocket is an amazing two stage design made to imitate a yellowjacket wasp. With its traditional layout and durable construction, the Yellowjacket offers a new rocketry experience. It was specifically designed to be 3d-printed without supports and to be easily assembled and yet withstand the rigors of flight. Designed for standard engines, the Yellowjacket can soar up to 800 feet, with an amazing two stage flight. Easy to assemble and thrilling to launch, the Yellowjacket combines stinging style with incredible performance.
Printing
This rocket can be printed in any plastic and is specifically designed for a 0.4mm nozzle. However, if printed with PLA it will be a one shot rocket. In order to make the rocket reusable, you'll need to print in a higher temp plastic such as PETG, ASA, or ABS. Using PLA will cause the recovery charge in the engine to fill the body cavity with hot gasses that will melt the rocket. Supports should not be necessary on any parts.

Recommended Plastic
| Plastic | Performance |
| PLA | Not recommended (One shot rocket) |
| PETG | Acceptable (Will likely survive but not certain) |
| ABS | Recommended |
| ASA | Recommended |
Because of the very small surface area touching the build plate, make sure it is very clean and use a brim when printing. PEI build plate recommended. If you have difficulty getting the prints to stay attached, wipe the plate down with steel wool (#0000) and wash with Dawn Powerwash. Be sure to NOT touch the build surface or rub it against anything that may have oil. If you do, wash it again.
Assembly
See the included Model Rocket Assembly guide PDF.
For additional stage, use an engine mount, engine cap, 4 fins and the multi-stage adapter. Glue the multi-stage adapter to the top of the engine mount instead of the chimney. The multi-stage adapter will fit over the other engine cap.
