Our local DE had a 1-35 on the line, which he mentioned to me when I
mentioned my plans to buy an HP-11. He gave me some advice then, and
in retrospect it was very good advice.

First off, flaps for glideslope control are not an issue. Really no
big deal at all. Sure, a little different, but not difficult.

The issue with my HP-11, and the HP-18 my friend had, and the 1-35 the
local DE had, was weak aileron control on takeoff. On a wide grass
field with a powerful tow plane and all tows into the wind, it's not
much of an issue - you rudder it around until the ailerons come alive,
and then all is well. On a narrow paved runway, with lights on posts
giving the wingtips just a few feet of clearance, a weak tow plane, and
a habit of towing slightly downwind to avoid the inconvenience of
moving, it's a much bigger deal.
