What is the consensus of opinion of using steel thimbles on aero tow ropes? Currently we use some clear tubing in the loop to protect the rope from wear of the Tost tow ring. Not only does this allow the rope to bend sharply causing a weak point but it also seems to fill with dirt. This then...

I have just sold my Garmin Pilot 3 and want to upgrade to another Garmin, possible a 196 or a 296. I have a mate with a 196 and it does a great job. Has anybody had any first hand experience with the new colour 296? What is the colour screen like to read especially in a sunny cockpit? Is it worth...

Hi, I am seeking advise on the replacement of the wing pins fitted in the end of the spars on Grob 109 and 109B. This also applies to the Grob Twin Astir. A brief history. These pins are welded to a plate that is glassed into the wing spar end during manufacture. It was found out at a later...

Hi Olin and Mary Merry Christmas!! http://www.go.ednet.ns.ca/~larry/ -- ----------------------------------------------------

Reducing the drum size has more effect on torque than I realized. My spreadsheet shows 953 lb-ft for 48", 242 lb-ft for 36" and only 85 lb-ft for 24". What do you think? Bob --

Has anyone found a non-bending swiveling tailwheel for this ship yet? Thanks and all the best --- Bob Johnson ----------------------------------------------------

and anyone else that has not grown weary of this Winter subject-- Every site from to FAG Aachen to AC Zwickau is represented. Mostly German but I notice Prescott, AZ is in there with some mighty good looking equipment! Enjoy-- BJ

Don't overlook the advantages afforded by the incredible lightness of this new type of rope. Mass and ground friction of comparable towline diameters are reduced a whopping 80 percent. Ground run distances for heavy two-placers are thus reduced 25 percent and the ship gets into the air in 2.5...

How could I have forgotten the swivel? You won't need one -- the untwistiness of this woven rope is legion! BJ

Does any aerodynamisist (!) out there have an opinion concerning how much higher than unity the drag coefficient of a rope or wire cable is likely to go? TIA, BJ

This has been covered in these pages before, but it may be timely to post it again in view of the coming fuel price squeeze and the increased interest in winching. This Excel spreadsheet explains mathematically why a winch system comprised of lighter linear (rope) and rotational elements...

It wouldn't hurt to repeat this message also -- any location thinking of going to a winch operation would do well to absorb the lessons in Derek Piggott's "Ground Launches" book. This 83-page book distills over forty years of European and British winch experience. The author has had over 10,000...

There's a good discussion of this subject in the current issue of "Flying" magazine written by the editor-in-chief, Richard L. Collins. This monthly is of course chiefly aimed at General Aviation (read power) pilots but there are several points Collins makes that could profitably be extracted for...

Further to Craig Freeman's post of July 28, photos of our new winch are available at our club web site at http://www.permiansoaring.us/ The winch was conceived and built by Craig in about three months of spare time work, which is surely remarkable. Even more remarkable, Craig also wears additional...
