Any one had problems with a NASA wind instrument reading low. And how accurate can I expect the compass to be

Biggest problem is getting any reading as the masthead units usually fall apart!!!

Mine works just fine, and checked against Chimet via WAP while on Chi bar, seems pretty accurate. If yours isnt right, ask Nasa, they are very helpful.

My NASA Clipper wind instrument constantly reverses itself, and loses its setting often, usually have to reset its port/starboard memory, next time i am going to set iy wrong way round so when it reverses itself it will be right, i hope.Ive decided the cotton telltales on my spreader staywiress are more reliable and were so for all the years before i fitted instrument

I once broug a nasa compass and after 7 month it got all steamed up send it back to nasa who wanted to charge me for the repair , they said water must have got into it . they ask were i kept it and i told them it was placed by the wheel , they replyed that it should not be left outside as rain and sea water may get in it .. ha ha ha so there expect ed me to keep in inside the cabin ""some one please tell me how do you stear by compass when its 4 mts and inside .. told them to keep it .. never buy another nasa again....

Our NASA wind instrument can read very low occasionally when the masthead unit is in the mast's wind shadow - otherwise it seems OK. How do you know it is reading low?
The fluxgate compass is a pain to steer to but seems reasonably accurate - it is adjustable somehow, but I've never bothered - we use the GPS repeater as our main nav instrument and just use the compass to check drift rather than to steer by. I want to replace it with a decent mag bulkhead compass if I can find somewhere to put such a thing.
