Maybe someone with a light xtra can throw in an 80lb sand bag, wait they don't make sand bags that heavy, well grab a couple and tell me what performance I can expect. Instead of flying like I'm 180 it will fly like I weigh 260. Im one of those guys that doesnt like the BRSs because I dont want to give up the 20lbs every time I fly, shoot at least that 20lbs might save my life this 80lbs does nothing for me and I'll have it EVERY TIME I FLY! A month or so ago, I ask the list if there were different versions because I had heard there might be. I got answers that the stabs were different; no one mentioned the 80lb difference. I found out today that I should of ask the Kolb company, my bad. Im done venting. Ive ask the Kolb company for the numbers to the plane Ive bought. This is probably one of those times where I should keep my mouth shut.

David, If you have flaps instead of the flaprons, you also have more total wing area. You will NOT have an increased take off roll or landing roll but shorter.

Not as far forward as LandShorter recommends, and not as far back as the flashing type that are common on Kolbs. I'll get some good data after I fly in smooth air, but for now it looks promising. -------- John Jung Firestar II N6163J Surprise, AZ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=21859#21859 ________________________________ Message 21 ____________________________________ Time: 11:00:31 PM PST US Subject: Kolb-List: Re: Heavy Xtra :-( From: "JetPilot" --> Kolb-List message posted by: "JetPilot" dhkey(at)msn.com wrote: > > > Im one of those guys that doesnt like the BRSs because > I dont want to give up the 20lbs every time I fly, shoot at least that > 20lbs might save my life this 80lbs does nothing for me and I'll have it > EVERY TIME I FLY! > > Your reasoning on the 20 pounds is just plain wrong. A BRS is much more likely to save your life than to cause any type of problem... From the sound of your post, it seems that you are obsessing about weight to the point of ignoring all else. Obsessing on one item is always bad, everything is a trade off. Having a plane that is stronger might be worth the extra weight. The most likely accident scenario is that your engine will quit, at which point you will be comming down weather your plane is heavy or light. At that point the more heavily built cage might be a good thing. The MK-III is a pretty big plane with lots of power, 80 pounds is about 13% extra and wont kill the performance. More important than the weight is how well it is built, covered, etc... If its a nice plane with quality workmanship, dont sweat the weight issue to much. Michael A.
