Automatically controlled two-bladed propeller.... Designated the Variostat HO-V62A, it is designed for engines up to 100HP... It is automatically protected against overspeed in all flight conditions and maintains constant speed from take-off onwards. All adjustments within the variable-pitch range can be made without the use of a control lever or selector in the cockpit. The pitch change mechanism has its own oil system.... Four adjustments are possible on the ground : fine pitch, coarse pitch, maximum rpm and rpm for reversion to fine pitch.  1, fiche 2, Anglais, - automatically%20controlled%20two%2Dbladed%20propeller
