Club Homepage Forums Classified Ads Buy & Sell - Everything But Airplanes FS: Airspeed Indicator

Good day all. As the topic says I have a Removed Serviceable Airpseed Indicator (True Airspeed Indicator) for sale. P/N S3325-9, S/N T43897B, Date of Manufacture Oct 09, 2005. Its made by Sigma Tek. As you can see in the pics it is a 40-200 knots. All that I can find on the great Internet, is that these retail for about $1800 from Cessna new. I am by no means looking for anything close to that.

Make me a reasonable offer, and its yours.

A quick little backround on this instrument. I removed it from my Cessna 150E, and installed a Original MPH gauge. As some of you know, I don't have my PPL yet, and bought the plane to get my PPL. Well all the speeds in the POH (owners manual) are in MPH, and this one is in Knots. I'm having a hard time with remembering somethings in knots and other in MPH, so I just went and installed a MPH instrument to save me the aggrivation.

I'll leave it here for a few days before posting it on Barnstormers or eBay.
Thanks
Mark

What plane is this designed for ... With the white arc up to 100? Would that be a legal instrument in a 150?

Good question. Just because it was "removed" from a certain airplane, that doesn't mean it was the correct one installed. The required markings for a particular make/model airplane are found on the TCDS. That may be a nice instrument (SigmaTek are very good), but you would have to have the dial markings changed to what are required for installation in a Cessna 150 or 152..

When I first read this I initially thought what 150's are you talking about, Edward? I was pretty certain that all 150's had an upper limit of 100 for the white arc?

MPH!

That particular one appears to have come out of a newer production 182 or 206.

Wentworth has had > this one < [ebay.com] listed on ebay several times in the past month, for $195.00 with no bites, whatsoever. The Wentworth model appears to be out of a newer style 172.

Mark, from the trend I've been following on ebay, most of the newer (used) versions of this particular instrument are selling in the $50-$150 range. The drawback for installing it in a 150/2 is, one needs to send it back to Sigma-Tek for refacing to match our speeds. The TAS window is, pretty much, unuseable at our speeds of 90 knots / 100 mph. Now, for a 150/2 with a 150hp conversion, the current (ebay used) Wentworth 172 model TAS indicator would fit nicely, as the window for the correction is closer to what the big nose version would be making.

Good luck with the sale!
