5 yrs ago i bought a falcon asi for use as a backup from aircraft spruce. i am done building and ready for inspection. today i noticed my asi read 50 mph.i know it can't go that fast in the hangar. a call to falcon and i was informed the diaphragm was blown and repair would cost as much as a new unit. the topic that the diaphragm might have been defective was never offered. i, like everyone else on this forum knows that any air introduced into an instrument can ruin it. i would never have done that. anyway.............does anyone have a used 31/8 instrument they would like to sell? it's for a 12.
thanks.
thanks.
