  1. The legs are shaped balsa. The thighs, calves and feet are shaped seperately and then glued together at the knees and ankles. The upper legs were hollowed out a little. Upper legs done. A piano wire shaft gets epoxied into each upper leg later on.
  2. Balsa infill on the leg mounting The leg mounting done. Brass tube bearing for the leg axles to rotate on
  3. The arms are shaped balsa. They may have thin ply glued onto the rear, I do not remember. I had forgotten to make attachment points for the steering lines on the hands. These were made from brass sheet Brass sheet is pinned and glued in place The brass attachment plate is covered with a little balsa and shaped.
  4. Once the lines had been threaded through the sleeves and cut to the correct lengths they were sewn onto the parachute material at the outside edges so that the parachute would not be able to slide up the lines.
  5. Measuring the lines lengths. They are slightly stretchy, which didn't help... All done. All the lines attached and rolled up so as not to get tangled.
  6. The making of the final parachute. Not perfectly sewn together, its really difficult to get all the gores to lign up perfectly. But it works. This little toy skydver was implemented as the pilot chute. Ordered from Banggood. And that is the little 4 channel RX...
  7. The second chute a and the final one were test dropped off a 60 size stick. The pilot had his hands full with 750 grammes added well behind the planes CG....and then suddenly be removed again... These tests revealed that the second chutes material was too heavy. The third chutes material was then lighter and works perfectly. My little camera recorded the drops. Not to mention the roller coaster ride to altitude..
  8. This was the making of the first parachute. Much the same procedure as the refuse bag one but I had to buy a sewing machine an learn how to sew therewith.
