MK3A Rebel (K0001) Build Part 5 - Final Assembly and Paint Prep

Build Elmers Wood Filler Finishing Kit MK3A Part 5 Rebel Stand XROX Aerospace

Part 5 of this blog series assembles the parachute, performs the final assembly and does more paint preparation.  If you missed Part 4 of this series, it is available at this link.

For Part 5, we will need:

  • Parachute Kit (Part #12)
  • Booster Section from Build Part 3
  • Payload Section from Build Part 4

During this series of steps, additional work is done to prepare for painting the rocket.  If you prefer to finish after the build is complete, omit those steps.

Build Steps
  • Tie the free end of the shock cord from the assembled payload section to the screw eye on the chambered baffle using a double knot.  Apply a small amount of white glue to the knot to hold it in place.

  • Inspect the contents of the parachute kit.

  • With the parachute from the parachute kit, cut the outside of the parachute to the 18 inch size.

  • Cut the parachute shroud line string in to 3 equal lengths.

  • Apply the reinforcing tape disks to the parachute, where indicated.

  • Punch or cut a small hole in the center of each reinforcing disk.


  • Tie the ends of the shroud lines through the holes in the parachute in the pattern indicated.


  • Gather the shroud line to an apex and loop through the snap swivel.

  • Clip the snap swivel to the eye hook on the chambered baffle.

  • Roll up the parachute and pack it and the shock cord into the payload section.

  • Insert the chambered baffle into the payload section to finalize the assemble of the MK3A Rebel.

 Finish Preparation
  • Apply a generous coating of thinned Elmers Wood Filler to the nose cone (Part #1) and to the chambered baffle (Part #5).

  • Sand the filler smooth to the profile of the nose cone and the baffle using 220 grit sandpaper.  Be careful at the seam transitions of the body tubes and the 3D printed pieces to not over sand and cut into the paper of the body tubes.

  • Apply a light coat of gray automotive primer to the whole rocket.  Set aside to dry overnight.

TIP: To better seal the ends of paper tubes, wick a small amount of CA (super) glue into the ends of the tube.  This will stiffen the tube and help prevent the "fuzzing" that occurs from over-sanding.

That's it for this post.  Take a look at the stand the the MK3A is on. 

Later this month XROX Aerospace will release these stands in two packs.  Keep an eye out for them on the web site and in social media.  In Post 6, the painting is completed and the decals are applied.

As always, I encourage you to take a look at the XROX Aerospace MK3A Rebel product page.  This is a unique kit that is simple to put together and fun to fly.

Happy building and safe flying.
