Yuan,   Thank you for showing the weight of parts of your Pennyplane as I am a
new builder and its nice to know if I am in the ball park with my parts.

Thanks for sharing TOT. It has an interesting appearance, mixing an old-style

Before Warren Williams set the impossible Cat I LPP record of 16+ minutes, the
record was held by Jim Clem at 11:48. We can use the Clem record to better gauge
Cat I LPP flights.
