skid68 Posted March 31, 2015 Posted March 31, 2015 Very cool. I'm looking to make something similar, but with a strobe pot. What material are you using for your parachutes?

skid68 Posted April 1, 2015 Posted April 1, 2015 Nice, thanks for the details.Did you sew the strings/ropes to the chute, or just glue them? Have you had any problems with it catching fire being partly polyester?
