You'll notice that the proportions are somewhat elongated to make it more like a 3 channel motor glider than a scale or back & forth model.
The wing was made from the same blue foam core that he uses in his F1C folding wing design with a tapered .005 carbon fiber spar top and bottom. The wing is then finished with a vacuum adhered 1.5 oz glass cloth that has the grain oriented at 45° to the cord and span. It is incredibly rigid. Weighing in at 17oz, it is 8oz to the square foot.

| So far, it has only been test glided. |

| No landing gear, just 2 wire skids |

| He drew his own plans and figured out the radio installation better than many who've flown R/C for years. |

| This Taube by Fred Mulholland from 4 yrs ago was the inspiration. |

Made about 6 flights Monday. It was very flakey and unstable -- I thought it was just me over-controlling but determined that it was tail heavy in addition to my inexperience. That fan shaped stab doesn't support much. Also discovered that left turn works but right not because, I think, the stab blanks the helical prop wash to the right rudder but not the left rudder. Okay at high speed and in glide.
I have now moved the CG forward from 50% to 45% and added 1.5 degrees incidence to wing and hand launch tests at park now much better and consistant. Will try again Sept 10-11 at Muncie.
