With a lower Vx and Vy, the rate of climb will be higher and the power-off glide ratio will be better. Longer wings are more aerodynamically efficient than short wings. The trade-off is that they are either structurally weaker or heavier.

It'll vary a lot depending on aircraft weight, prop choice, etc. You can find performance figures on several "plain ol' 2's" by surfing the various web sites of flying KRs with an 1834 (or 1835). If you start on Langford's, Mimm's, or Adrian's site you'll find the links to the others. >I would like to know if there are any KR2s,s out there tooling around in >a 1834 V/W ., and what kind of performance you're getting. I'm currently working on smoothing out my KR2 to increase performance, the original builder left it somewhat lumpy. Flight testing should take place next week, weather permitting. Maybe I can talk Oscar into going along and tracking the new numbers :-).

Mark Lougheed dutifully scanned them all, and posted them at http://www.geocities.com/krnewsletters/ . If you haven't read every single one of these things, you need to quit what you're doing and go read them! That oughta keep you off the streets for a few weeks...

Well, I guess there's always Diehl Aero-Nautical, 1855 North Elm, Jenks, OK 74037 (918) 299-4445, Manufacturer of wing skins, VW engine accessory cases, tricycle and conventional landing gear.

Subject: Homemade water-born epoxy filer Message-ID: <3964C60A.C823689F@wanadoo.fr> As a very beginner, I try some glass lay-up work. I found in the "Understanding Aircraft Composite Construction" two interesting tips: 1. The "extremely" dry micro - I poured some microbaloons directly on the wet layer to obtain an easy sandable surface after the epoxy has cured. After curing, I cleaned the dry bubbles and I found some very rough surface. The layer is easily sandable but the finish is quite worse than the "deck cloth" method; 2. Water-born epoxy filler - I took some peanut butter-like micro and put in it several drops of water. The water do not mix at all with the epoxy but after stirring it thoroughly, I obtained some light honey-to-mayonnaise-like "colloidal" mixture. I could spread it easily using a 6" rubber squeegee on the cured 6 oz glass layer (without any deck cloth). In fact, the result was the same as on the photos in the Superf*l manual, the micro was enough runny. The small quantity of water stays on the surface and evaporates quite fast. After curing, I obtained the same hardness as it was a dry micro. Any comments would be appreciated.
