Estes Pegagus #0806 Wings

thingiverse

Files to print wing structures which are very similar to the Estes Pegasus #0806 model rocket's original design. The single wing is sized exactly like the original, while the scaled and mirrored wings are designed for direct attachment to a BT-5 body tube without an internal engine mount. Print Settings Printer: Custom Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: High (0.3 to 0.2 mm layer height) Infill: Your choice, though I use about 30% to save weight Notes: The scaled and mirrored wings may need support for the tube area, but this area is very thin and difficult to clean out. Post-Printing Assembly (Full Size) Parts for the complete rocket can be purchased online. I bought body tubes, engine mount hooks, shock cord, parachute, and nose cone separately. To assemble the full-scale wings, print the original and a mirrored copy, then clean up as needed. I used 5-minute epoxy to attach the wing tips to the wings, which are dovetailed for strength. Some minor filing, sanding or cutting may be necessary. Next, glue the upper dorsal fins to the engine pods using 5-minute epoxy. Attach the completed wings to a BT-20 body tube, making sure to fillet the glue over extra area on the body tube for added strength. Assemble the rest of the rocket according to the original instructions (http://www.spacemodeling.org/jimz/est0806.htm). The wings are much heavier than the original balsa wings, with each wing assembly weighing about as much as the complete original model. I used 13mm A10-3T Engines for a fantastic launch and recovery within a football field-sized area. Don't use smaller 13mm engines like 1/2A3 or 1/4A3, as the model is too heavy and your rocket will likely end up nose-down in the ground before the parachute deploys. Assembly (Mini) Parts for the complete rocket can be purchased online. I bought the body tube and parachute separately. I printed a nice nose cone from http://www.thingiverse.com/thing:559583. Print the scaled and mirrored wings, which are scaled down to about 75% of the original size to fit directly onto a BT-5 body tube. Clean up as needed. The wing assembly has two small protrusions inside the round body tube attachment area to prevent a motor from being inserted too far into the body tube. I used 5-minute epoxy to attach the wing tips to the wings, which are dovetailed for strength. Some minor filing, sanding or cutting may be necessary. Glue the upper dorsal fins to the engine pods using 5-minute epoxy, then attach the completed wings to a BT-5 body tube. This model is very light, and I easily used 13mm 1/2A3 engines with great results. However, without an engine hook, the engine would release from the body tube instead of deploying the parachute due to the tight fit of the parachute in the body tube. I recommend using an engine hook and thin shock cord or fishing line as well as a streamer instead of a parachute. How I Designed This I designed the files by using the original instruction and layout cards from the kit. I drafted the parts on SolidWorks and then fine-tuned and modified them as necessary. Future versions may be thinner in some areas to reduce weight.
