I found a picture of c/n 088 a couple weeks ago and while trying to identify the photo I found another taken last july.

This is kind of an interesting Helio instead of converting the Helio to H-395A configuration the exhaust augmentor was retained and rebuilt using more modern materials, I think one of the main things was using perforated stainless steel instead of aluminum in the inductor actually I would like to know more. I think it may still have the original muffler under the cowl (I'd like to take a look under the cowl). It is reportedly probably the quietest Helios in the fleet

I remember hearing a story that when landing at one of the small FBOs for fuel or whatever, the operator didn't even hear him taxi up. didn't even know he was there until he knocked on the door.

Each of the last four pictures has a little bit less blue I wonder if they are getting ready to paint it.

I will open the two photos at the bottom above.
