I can't believe nobody has hit on the obvious...............LOW JACK! Tim

I love to spin. It's exciting. I took aerobatic training with Wayne Handley and was taught spin recoveries by him. I have direct experience spinning the Puchacz at Minden. This is what I remember from my experience. Your mileage may vary. With friends (usually lighter than me) in the front, I spun...

I am working though some calculations and need the sink rate as a function of speed with the spoilers fully extended. Does anyone know of such data for a glider? How do spoilers extended affect sink rate as a function of speed? Thanks, Tim

I am working with a fourth printing (1988) and the equation presented for Optimum Average Cruise Speed does not make sense. It is equation VI in the book, but it gives a very slow speed to fly compared to the graphical approach of just finding the tangent to the line. Plugging in zero for the...

Are there any working designs for an air extractor for the Ventus 2?

I am looking for an article that was published in Soaring on a study of differences between new and expert cross-country pilots. It was published about 20 years ago but I can't remember the title or author. Tim

My trusty SPOT gen1 has developed a bad on/off switch. The GEN1 was very good and almost never missed a data point. Any reviews of the gen3 vs the origional? TT

I am looking for a LXNav FlarmView 57mm to try the PEV function with the PowerFlarm. Contact me directly at TTaylor07 at gmail. Tim

Like first ascents in climbing, first ridge traverses in soaring can be challenging. We had the pleasure today to do a first traverse on the Wyoming Range in western Wyoming, just south of Jackson Hole. Many years ago I pioneered the ridge run on the Salt River Range, it took several years to...

I was thinking we really needed one to test fly flights. Did a search and found this: Google Earth's Hidden Surprise: A Flight Simulator Duncan Riley http://www.techcrunch.com/2007/08/31/google-earths-easter-egg-a-flight-simulator/ We've always known that Google has wanted to challenge...

As the cold weather is appraoching in the northern hemisphere what antifreeze can be used safely in integral water ballast tanks such as in my Ventus? Also where do you buy it at a reasonable price? I am guessing the maximum use would be about 25% v/v at any time. I think I could often use 2gal...

Background The 700 km flight on October 3, 2007 was the result of several years of experimentation and planning that allowed the first flight exclusively in ridge lift from Salt Lake City, Utah to Pocatello, Idaho a distance of 145 miles (233 km). The flight planning began several days earlier...

I am getting ready to replace the panel in my Ventus B. Are there any standard materials (especially the core) and recommended glass and core thickness used to layup a new one? This is a fixed panel, does not pop up when the canopy is opened. I was thinking of using a 1/16" to 1/8" core of...

I will move this out of the "Stay in, or get out?" thread for clarity. I have long thought about helmets for several reasons. I will state up front that I have not had access to the accident reports/pictures and autopsy reports of several of the accidents that I have seen over the last 25 years,...

I will be in Cuzco, Peru for about three weeks in May and was wondering if there are any soaring sites in the area. So far I have had no luck finding any in Peru at all. Thanks, Tim

Works perfectly, calibrated August 2005. Includes all cables and antenna. $700 USD.

On a recent flight on December 15th I had an interesting experience with our local Terminal Radar Approach Control (TRACON) group at Salt Lake City. I was on the final leg of a 500K ridge flight that took me through the 30nm Mode C veil several times. I monitor Approach Control frequencies and...

I am working with a potential supplier of a replacement for the Bosch CDI electronic ignition units for the Rotax 505 engines used in many early motor gliders. He would like to be able to look at an engine to determine the exact specifications for a replacement CDI module. He is located near...

Gart Sports (located in many Northwestern US states) has a sale this week on Magellan 310 GPS units, $49.99 USD. No reason not to own one at this point. The Logan, UT store said they had plenty this morning. To find stores go to www.gartsports.com Good luck, Tim

I don't usually look closely at the OLC scores for flights but on a recent flight I was given a very short triangle that didn't make sense. When looking closely, I noticed that some legs were scored shorter than they should have been by several km. The triangle was scored at about 15 km rather...
