Howdy all! News from Hollyday's for our friends on the list: Baby girl born 6/11/02, Christina. Momma and babe doing fine. Her 2 big brothers are a little jealous.
I wanted to reply to the thread about rubber protection. Armor-All and other consumer brand "protectants" have petroleum penetrants to make them 'work like magic' on synthetic plastics, but it kills anything not plastic in short order... like leather and natural rubber. Here are some links to more info: http://www.hollyday.com/rubber.htm http://www.hollyday.com/hsfaq.htm http://www.si.edu/scmre/rubber.html Mandrel dipped rubber, as sold by Aerofoam at http://www.aerofoam.com/hosemonster.html, is very tough. The grit issue (abrasion) during storage is not really a big deal, as it is with smaller cross sections of the extruded stuff. It can take the rough grass and gravel where we are sometimes forced to fly. The real killer is the UV hardening. Lubricants are used on rubber powered free flyers to reduce rubber to rubber friction while winding millions of turns into a rubber motor, to avaoid breaking at higher winds. Not related to rubber protection. Merely stretching a rubber close to the point of breakage breaks down some of the internal structure, so expert rubber fliers will replace their tan rubber before chemical breakdown is much of an issue. Even dipped tubing will lengthen about 1% after stretching to 350%. Repeated stretching to the same distance has no further effect. Mark at Aerofoam.com and Dieter at Shredair.com have been working hard over the last couple months to bring their versions of rubber and switches back to market for everyone. Much appreciation, guys! I will be adding links to their pages on Hollyday.com. We miss you all and wishing you lots of thermals this summer.
