I have an old Crosfell in my shop that I'd be happy to see find a good
home. No idea if it runs or not.

I had a crossfell in the Cherokee when I first bought it. It was
running on three D Cell Batteries at the time. I think something was
reversed as the vario would show negative when I was in lift and
positive in sink. the scale was way off too as the strongest lift I
was ever in only registered at about .5 m/s. but it worked once you
figured it out. still is sittin in my hangar. should still work as
described, have removed it and all the hardware, including a diaphragm
total energy system.

bob didnt you help get my Cherokee airworthy again in lawrenceville?

Hey, that takes me back! I think they ran on 4 1/2 volts.

We didn't have a lot in the way of electronics in those days.

I have 10 pages of original documentation on the Crossfell Variometer which
I obtained from a fellow in Canada some years ago. This documentation
includes circuit diagrams, specifications, etc.

These pages show the instrument as running on 4.5 volts, with 4.2 volts as
the recommended minimum.

Send me a direct email including your address if you would like me to
photocopy and post this information for you.

I have a Crossfell set aside in my gliding kit but no time to put into it.
Currently stuck with trailer building.
