One thing I observed on glide testing was that the wing inverts mid flight and falls down...
On using an avispad fuse with this wing... it glides nicely.. is there something wrongs

Just struck an idea... I will prepare this model for chuck flying this Sunday  and make it adaptable to take power systems later on after march when I get them...
Is it feasible?

A slow flyer high wing trainer is your best option.  All of my GWS Slow Flyers have thin under cambered wings.  It's impossible for them to go fast without losing stability or without nosing up.
