ProteusV2

This version of the Proteus slope-soarer has changes to the sweep, washout, fins and elevon hinges, to improve the flying characteristics.

In particular, increasing the leading edge sweep from 22 to 26 degrees has greatly reduced the likelihood of spinning out at the top of loops.

Increasing the sweep also results in the CG moving backwards, so no lead nose-weight is needed now (using 4 AAA NiMH cells) and it still flies well with the CG 5mm to the rear of the dimples on the fuselage.
