The 'Piggy Plane' (Swine Flew embryo)...trying an ROG for the first time. Film shows the attempts of launching via "Rise Off Ground", the rubber-powered free-flight model of the pusher-canard Swine Flew embryo from a table top. The model was designed by the late Bob Gable, built by Tom Hallman. Graphics by granddaughter, Zinnia Jane. Model weighs 19 grams. 17-7/8” span. Filmed with an iPhone 11 & 14 Pro, and a Canon PowerShot SX20. Music: "Come On" by Effronté via Artist.io.

You can build the same model twice, yet they may need totally different trimming solutions. Therein lies the challenge & fun of rubber-powered free-flight.
