The 35.75" rubber-powered Hodek HK-101 free-flight model returned to Wawayanda. Built in 2016, the model came in at 82.77 grams, needed 1.75g of tail ballast, and uses an additional 34.78g of rubber. Each motor is two loops of .187" (3/16") x 34". Gives me 1650-1700 winds and 80-85 seconds or so of motor run with the 10.5" props. All up weight is 119.30g for a wing loading of .51gm.sq.in. Music via ArtList. Filmed with a Canon PowerShot SX20, and iPhones 11Pro & 14Pro.
