Diana4: maiden flight of the first!

Today we maidened the first of our three Diana4 – the one built by Georg. He finished it just last week (having started the build at the end of last year – very fast, as usual). His Diana4 came out at 6.4kg, 7.1kg with ballast.

As always with a brand new plane, it needed a bit of finetuning. Georg started off with the CG of our Diana2 (which has the same wing profile), but that turned out to be too far back. Also mixing in down elevator with the butterfly needed a few tries. Once he got the settings in the right range the plane just didn’t want to come down anymore. There is still some more fine-tuning to do, but it’s a wonderful glider that will surely see much “airtime”.
