Constant-speed Hamilton Standard airscrews are used, with
Arens controls. The tip clearance between the two airscrews
is only twelve inches and their thrust line, in reference to the
centre line of the machine, is toed out 4 deg.
Behind the cabin are the toilet and baggage compartments.
The radio equipment is also carried, entirely enclosed, in the
rear section of the fuselage.
The single-engine performance of the Alcor is said to be quite
exceptional, and the particular type of engine mounting makes
it possible to fly the machine '' hands off " on one motor. The
performance in these circumstances includes a ceiling of
12,oooft., climb of 300ft./min. and speed of 174 m.p.h.
The track of the Alcor is wide for the machine (13ft. 2jin.)
and the general ground handling is said to be very good.
