This is a project I took up as a offshoot to several physics questions about this plane, rather than as a direct special request. The weights of all components are set as if they were solid EPP foam (.0176 oz/in^3). An additional 10% has been added to the wings and fuselage to account for carbon fiber and electronics. This came out pretty much right on the money for the advertised weight. The rest of the physics are very straight forward.
Modeled for RealFlight by Doug Kaye (DHK79).
EDIT: This is a repost with a slightly more powerful motor. When tested in G5, it was discovered that the physics between the two versions was not quite the same and the plane was very hard to take off.
