I envy the cobra trailers with a jack that is removable. I can find the jack itself but does anyone know of a source for the bracket? This is the part/clamp that allows that jack to be removed. Anyone have a old rusty jack/bracket lying around?

Look up Knott GmbH trailers out of Germany. I sourced a tongue damper with very positive results. Check the data plate on your trailer tongue for your equipment mfg.

This is a (very nice) homebuilt trailer so no dataplate. I am trying to replace the standard "American" jack with a removeable "euro" jack. http://aviation.derosaweb.net/dg101/...3405_Large.JPG |

Thanks for directing me to http://www.knott-trailer-shop.com. They have exactly what I need.
What seems crazy is how inexpensive the parts are (shipping may be another story). The jack is E19.49 ($24.12) and the bracket is E6.00 ($7.43). Williams Soaring has the jack for $254.30 and the bracket for $44.22. 9.5x more expensive??? Am I missing something? And I'd like to mention that the http://www.knott-trailer-shop.com web site is one of the best I have used. - John |

Works well, swivels up out of the way for travel, only $30. Go to westmarine.com and search for "swivel jack". -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) |

Eric Greenwell Eric - Thanks for the comment. The type you describe is the type that I have now and it is fine. But for various reasons having to do with space considerations I want the removable type. It seems that here in the US no such item is used or available (except from glider trailer parts sources). However, in Europe and elsewhere, it is the standard. It took me a while to figure out that a "swivel jack" in US- speak is a "jockey wheel" in Euro-speak. American doing its own thing I guess - and don't even get me started on why we are the only country that doesn't use metric (except for Liberia and Myanmar!). - John "Metric" DeRosa |

So... If you're sinking at 1 meter/sec and cruising at 100 km/hr, what's
your glide ratio? If you're sinking at 2 kts and flying at 60 kts, what's your glide ratio? How many km per degree of longitude? How many nm per degree of longitude? I could go on...

I use McCready numbers for the speed to fly and for the glide calculation, which is done by my flight computer. As for km, NM, and degrees of latitude, I also let the flight computer work it's magic.

Frankly, I see no value in switching. I already have two sets of tools, SAE
and metric. If we switch, then my SAE tools will become redundant. Heck, my Harley-Davidson requires both sets of tools (sheesh)... "Eric Greenwell" wrote in message ...
