My Guppy has made his maiden fly today with the hotliner wing. Flying the glider in this configuration is really fun! I was surprised because the glider can fly very fast (I do not observe any flutters on the tail). The ailerons are powerful. At low speed, the glider still stable and secure.
Here is a picture of the Guppy in the hotliner configuration and an other picture with the polywing.
