CG Calculation:

You wont get the oral explanation, but it shows how to make the wings.

That was one intense launching technique, Bud. Nice work.

Yupp - but it is the only way to launch it alone. Just try tossing 3 kilos over your head, and find the way back to the radio before it starts plowing earth ;-)

PS !!! It is also the safest way to launch - you dont want that propeller cutting your fingers.

Looks like an awsome build, how are the stall characteristics?
This will probably be my next build!

At :48 did he say that each wing has a turkey-seven inch wing chord? Just kidding. I just finished a similar build out of bluecore foam that has a 42 inch wingspan, weighs in at 24 oz. It flies awesome. Great video!! Keep it up!

KaptenKlister: What should I answer.... Like all planes i will stall, and I have not collected data for how low sped I can do with max up angle. Will look trough the GPS data.

However it flies extrodinary stable. I will update the article with raw GoPro footage - absolutly unstabilized from my channel.
