Beautiful paint. Possibly unique HP-11 in that the flaps and ailerons were manufactured with the correct airfoil instead of the straight bottom surface. V-Tail fixed and nicely faired, unique trailer designed to accommodate.
The below picture shows a Tasmin Variometer with, ILEC repeater (which I normally keep set on "Variometer"), Winter airspeed indicator, ILEC SB-8, and altimeter. The Garmin GPS III provides data to the Compaq 1530 PDA being held by a RAM mount.
The center pedestal contains an electronic compass with 1/2 degree accuracy; Filser 57 UL VHF radio; and, quartz electronic clock.
