Notice my name or products has been used a few times. 1 I certainly agree with air vents say infront of compass and cover inside of hole(s) with fly gauze & this idea certainly came from Mike. Electrics hate excess heat so PLEASE do this during this winter.
2 Pilots have alerted me to the faster, 0.9 lit Winter vario & I now recommend this unit & the only one I stock these days. Another good Winter vario is the logarithmic which has expanded in low range but have not flown with this type recently. 3 If using a mechanical then T as close to probe as possible (minimum under spar). Some pilots have an air switch so winter is not on probe & they cover up the mechanical but can always be uncovered and used if electric failure. 4 Statics etc MUST be covered up if rain is around & in hornet season the worst is a partly blocked tube. 5 I am sure all varios brands are making quantum leap forward over the last few year and especially on those gusty broken days. I can say ClearNav vario is much improved (esp the latest version 3.0) over the earlier Cambridge 302 which I considered was a great vario but is now 10 years old. If you would like to try a clearnav vario just ask for a loaner. 6 I think many vario issues are associated with plumbing. Eg partly blocked line, leak with old plastic plumbing (silicon tube always seals), leaking Winter case, the instrument barb on a winter flask being unscrewed slightly & slight leak, etc. Electric issues can be as simple as voltage drop across fuse because fuse has been heated by maybe a surge of power and that was also suggested by Mike guess 25 years or so. I could bang on about radio issues & is often aerial & power supply. I have an aerial checker (no radio needed) & again it is available for loan. Be real careful with a glider that has broken back or very early Cirrus or Libelle I built aerial or Nimbus 3 or 4 with aerial I rudder with that BNC that is not sealed from water. That's all for the moment.
