skid68 Posted March 31, 2015 Share 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? Link to comment Share on other sites More sharing options...

skid68 Posted April 1, 2015 Share 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? Link to comment Share on other sites More sharing options...
