I would like to double-check with the group several things an avionics shop recently told me: of the only 2 altimeters that are not-extremely-expensive and suitable for our Ercoupes (Kollsman & United Instruments), the Kollsman one is the sturdier and worth re- building, and the United Instruments one is very sensitive to vibration and not recommended for older planes that vibrate. The installed price for a rebuilt Kollsman was $350-390 (depending upon whether one left a Kollsman for rebuilding or took an already re- built one on the spot). I think he said the next thing up (a brand new altimeter) would be *way* up, something like $1500.
Is this correct? Thanks - Linda N3437H (Sky Sprite) 1946 415-C L.A.
