Hi-Start Rubber for under 3 meter (118") Sailplanes

1/4" ID with 3/32" wall thickness. Cross-section area is.1012 sq. inches. Weighs 4.5 pounds. Hi-Starts are huge gentle "slingshots" for putting a glider into the air. I use the word "gentle" because you and I both can picture that a Hi-Start might actually put your glider into orbit. Have no fears - a Hi-Start launch is a very graceful procedure that is a delight to watch (and more fun to DO).

These are 100 foot UNSPLICED tubes of latex rubber. They make the best possible "Hi-Starts" for RC sailplanes because they can be stretched 5 to 7 times their own length. The tubes are colored not only for better visibility when they are laying on the ground, but also because the color dies give the rubber protection from ultraviolet radiation and ozone.

In addition to the color dies the tubing also has a small amount of a microcrystaline wax in it. This wax migrates to the surface of the tubing appearing as a whitish dust. The purpose of this wax is to provide further protection against ultraviolet rays. When not in use these Hi-Starts should be stored in a brown paper bag or box. A waxed bag or box is even better. Storing them this way should ensure years of excellent performance from your Hi-Starts.
