Re: [Paparazzi-devel] The Flyaway Club site launch & submission contest

[Piotr Esden-Tempski]

I am glad to hear your report Christophe.

I reported our own flyaway incident, it happened in manual mode with no GPS and 
because of our own programming mistake. We could not tilt the vehicle enough 
against the wind to be able to bring it back, additionally we waited way too 
long before killing. We did not have another flyaway incident since then.

Cheers Piotr
