RE: [RCSE] how high really--Sorta
On a somewhat related note, I know some individuals have used a series of variying width white stripes on the lower surface of the wing as a means of estimating altitude. Obviously this method does not work for very high altitudes when the aircraft is at the very limits of one's vision. For us mere mortals however, it might prove useful. Does anyone have a reference, guide or link to information how one might go about utilizing these stripes as an aid? Specifically I am looking for suggested widths and placement of the stripes.

On another related note, most hunting scopes (for rifles) have graduated lines on the cross hairs to determine distance, the line spacing is typically the length of an average deer (about 6' but you need the specs for the scope). If you buy a cheap $20 to $40 9 to 20 power scope with a 40mm objective lens, you should be able to get a good estimate of distance based on the wing span against the reference lines, you should be able to see the plane much better too. Many marine binoculars also have similar reference lines. Mark Mech www.aerofoam.com RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] how high really--Sorta
The July 1998 issue of RC Soaring Digest described a pattern of chordwise stripes of varying widths (6 to 1/2) which can be used to estimate altitude. We'll make the article available as a downloadable PDF on the RCSD web site, hopefully tomorrow, Thursday. RCSE subscribers and rcsoaringdigest Yahoo! group members will be notified as soon as it's available. Thanks for the suggestion!
