Chipsair 2






Update of the first Chipsair that crashed due to unknown reasons.
Just lost it while spinning, maybe because the battery voltage dropped too far while tossing it around. Hence this one has a voltage display...

Update was build in very similar way to the first Chipsair but possibly a little stronger: Extra thin ply in the elevator, added bracing in the aft of the fuselage.

Wingspan 1.58 m
Wing Area 36.34 dm2
Tail 50 cm
Tail Area 6 dm2
Weight 2012 g
Wing Loading 55 g/dm2
Length 1.1 m
Airfoil Eppler E197
Engine OS MAX 46 LA (blue)

First flight on December 22, 2011, where I noticed at the field that the aileron hinges where actually not glued in, yet! So for the first flight scotch tape held them in place, and I tried to avoid aileron use to keep them attached to the wing.

The pictures also still show the push-pins on the windshield because I'm not sure if the glue is 100% dry.

This might have been the last plane where I could use the Pacer ZAP hinge glue that seems to become unobtainable.

Overall it flies GREAT. Plenty power, plenty authority from aileron and elevator, which I had worried about. Very nice and slow landings, while on the other hand endless loops and quite some vertical performance.
