Eric, can you explain span loading as opposed to wing loading?

That removes 100 pounds or so. I've found my 18 meter glider climbs as well as a typical 15 meter glider that has less wing loading. Span loading is an important number, so don't go just by wing loading. In the winter this means the non-engine folks have a much easier time staying aloft, and the motor glider in on the ground watching the pure gliders having fun.Start the engine, climb a bit, and go back to soaring. You will be able to do cross-country flights on the days the unpowered folk don't dare leave the field. The engine is your portable towplane, and even in weak conditions you might find, as I have, that you don't need it as much as you thought you would. Starting the engine might be the of competition or badge flight, but it's not the end of the flight or the fun. A few of my most memorable flights involved weak conditions and low cloud bases, but I had good soaring flights because I knew it wasn't going to end in a retrieve. Not that retrieves can't be fun, but after 20 years of them before I got the motorglider, my wife and I aren't missing them much! To the 26E, 808 list I'd add the Antares, and the Apis and Silent gliders (electric and gas versions). Lots more choices today than 10 years ago. -- Eric Greenwell - Washington State, USA Change "netto" to "net" to email me directly "Transponders in Sailplanes" on the Soaring Safety Foundation websitewww.soaringsafety.org/prevention/articles.html "A Guide to Self-launching Sailplane Operation" atwww.motorglider.org |

I did a lot of comparing and spent another 2 hours going back and forth
between the 26E and the 808B. The comparing included talking to people who worked on both these gliders, including Tom Stowers and Larry Mansberger (of composite fame). I chose the 26E. Subsequent to this, about 4 years ago, I've had much more experience and had the chance to really "go over" my glider, and look at the competition too. Even with the "C" version now available, I'd make the same decision again. Of course, it's to be expected that an owner will tend to favor the machine he has invested in - - I guess. The 26 is not perfect, but it's the very best 18 meter self-launch available, both mechanically, and esthetically too. bumper wrote in message oups.com...

What about the ablity with the 808 C comp to now fly at 10.4 Lbs verus
the 26's max wing loading of 9.2 Lbs, the stearable tail wheel and the ability to fill the gas tank from a truck or gas pump? I too think the 26 is "prettier". Does the large canopy of the DG cause relection and leak when it shrinks do the the cold from altitude?

So we have heard form two ASH 26 owners. Any DG 800-808 owners want to
opine? I have heard the build quality is better on the ASH than the DG, how so? It seems to me that Western flyers would want the extra wing loading in the summer. How do the cockpits compare between the DG and ASH? What about sealing from the factory?

This is best answered by really looking closely at these gliders. And if you're considering buying one, then it may be best to take the time to do this for yourself. I had the opportunity to do that to a degree on the SSA convention floor. I listed what I thought were the pros and cons of each ship to help me decide. Still, I missed a bunch of stuff, like the robustness of the 26's main gear, and many of the smaller things that I only discovered after really exploring the ins and outs of my 26E after taking delivery. Those that know me would vouch for this, I tend to be a perfectionist when it comes to things mechanical. I appreciate things that have been made well .. . . not just on the outside, but also beneath the skin. BTW, advantages I listed for the DG 800 series included: Much better factory web site. More progressive factory, at least in terms of being willing to quickly embrace new ideas and technology like NOAH and "Piggott hook". Lower cockpit sides for ease of exit. Two piece wings allow shorter trailer. bumper It seems to me that Western flyers would want the extra wing loading in the summer. How do the cockpits compare between the DG and ASH?

I don't know about the '26 cockpit, but I have experience in the '20 and
'27. They are both quite comfortable for me, at 5'-10" and 200#. My DG800B seems slightly narrower, but is wider than a LS-6. The DG forces a slightly knock-kneed position, because of the wider pedestal. Ergonomics and finish seem about equal. I wish DG would approve some really good fuel hoses---I have just spent the last 4 months trying to get the engine to develop full power. Finally, an engine bay fuel hose gave up the secret, by starting to leak! Replaced it and, viola, full power again! It spent 6 wk living with an A&P (approved) mechanic until it was found. The prop brake requires some attention to make sure it produces the needed friction. Ordinarily, engine retraction is as simple as can be. Handling is really nice---like a E series Mercedes Benz. No, it is not a Porsche, but I'll bet the '26 isn't either. -- Hartley Falbaum wrote in message oups.com... So we have heard form two ASH 26 owners. Any DG 800-808 owners want to opine?

So which one would you choose today? The Antares is much more expensive so that limits the market. I'd like to object to this comment. Before you decide on an aircraft (or make comments about their pricing), please get up to date offers for all brands you would concider, make sure that the offers include ALL the itimes you will need to operate the aircraft, then look at the BOTTOM line. The bottom line Antares pricing is competitive with similar infernal combustion based products. It must also be said that ALL sailplane manufacturers offer an amazing amount of product for the money they charge. There is a lot of idealism in the business. Anyway, if you are seriously interrested in an antares, then you are also more than welcome to make an appointment for a visit to Lange Flugzeugbau, including a test flight. Then you will know where the money goes. Contact information can be found at www.Lange-Flugzeugbau.com Cheers, Andor (yep, I work there) |
