  "I have used the wing of the P1-A Osprey and I also used the fuselage side as a template for the new fuselage.  The fuselage containing the electronics is 3/4th of an inch thick and was made from ten 1/16th inch thick hollow fuselage sections which I glued together plus two 1/16th inch thick fuselage sides.  I used the Brushed Micro ESC 1-2S 2 amp to power a Tactic TR424 receiver and two HK5320 servos to provide rudder and elevator control.

When launched from a height of approximately 1.98 meters, it will glide for a distance of approximately 23.77 meters.  It requires approximately 3.5 seconds to complete the glide.  This gives an average speed of approximately 6.79 m/s or 24.44 kmph and a sink rate of approximately 0.56 m/s.  Finally, using chart number 6 from the book “Understanding Polars” without Math, this information lets us compute the glide ratio in terms of lift to drag at approximately 11 to 1. I do not really know that much about gliders so I cannot say how well it compares to the average glider. However, I think it is decent performance from something which weighs 70.87 grams." - Carl

"This is a great build Carl, and the glider frames lend themselves very well to being fitted out with RC gear due to the cavity inside. I like the way you added formers based on the current body sides to widen the body." - Mark from MicronWings
