    1600-1800 fpm? That is as good a climb rate as I've ever heard of in any Kolb. Very impressive. I get huge rates of climb occasionally, when I catch a really good thermal. I'd like to stick one of those Jabirus on my FSII & & see what it would do. -------- Jimmy Young FS II, Generac V-Twin Houston TX area Read this topic online here: http://forums.matronics.com/viewtopic.php?p=243116#243116

    Chris, Those are really impressive numbers ! Do you have the Jabiru 3300 on there ? What kind of prop are you using ? Have you checked your indicated speed at cruise against your GPS to confirm that is actual speed ? I ask because my cruise is around 70 MPH at 50 % power. I can push it up to 80 easy enough but the power is quite high at that point and my fuel usage goes up a lot. What percent power is 2780 RPM on your Jab ? What is your climb RPM ? Hope you dont mind all the questions, but there are just not that many MK III Xtras out there that I have been able to compare numbers with.

    Mike, Climb rpm's are 3100 at 60 mph...Jabiru says cruise power is between 2800 to 2900 rpm's ...at 2900 it cruises at 92 mph.I had her up again this morning and I realy tried watching the speed and climb rate on my Lorance Airmap 1000 and it was climbing at 60 mph and showing 1400-1600 fpm with 1 notch of flaps...it seemed to go up when I retracted the flaps....Next time up will be no flaps and I'll see what the climb rate is them.The Jab is the A-2200,solid lifter 85 hp engine...ser # 1228. chris ambrose m3x/jab Read this topic online here: http://forums.matronics.com/viewtopic.php?p=243161#243161

    Very nice numbers, I am nothing short of amazed ! You must have a really big smile on your face after performance like that :) Normal takeoff would be no flaps unless you are on a very short or soft field. Flaps do reduce stall, but they add more drag than anything, so you will be higher more quickly without flaps on takeoff. The other reason to takeoff zero flaps is that if the engine were to quit on takeoff, you would slow down less quickly, and glide further without flaps. What kind of prop do you have on your plane ?

You can use the gps ground speed to get a pretty good idea of how accurate your asi is by flying a two way, 180 degree route, at the same indicated airspeed, dividing by two and comparing to ground speed. The MKIII, old one like mine and the X climb best with no flaps. My mkIII with 10 gal fuel and me will climb 2000 fpm at 65 mph indicated airspeed. The vsi needle is on the stop. That is on a good day. Most days it climbs about 1800 fpm. Cruises at 80-85 mph, trued out, at 5000 rpm, 75% power. Used to cruise 85 to 88 mph until I put the big Maule Tundra Tailwheel on it. The big tailwheel works so much better than anything else I have tried, it is worth the loss of cruise to be able to rely on it to get there and get me home. john h mkIII

    I think we are all scratching our heads because you are out performing a Rotax 912s... with a shorter and less efficient prop...theoretically...anyways,...Herb At 01:05 PM 5/8/2009, you wrote: > >Mike, > > Climb rpm's are 3100 at 60 mph...Jabiru says cruise power is > between 2800 to 2900 rpm's ...at 2900 it cruises at 92 mph.I had > her up again this morning and I realy tried watching the speed and > climb rate on my Lorance Airmap 1000 and it was climbing at 60 mph > and showing 1400-1600 fpm with 1 notch of flaps...it seemed to go > up when I retracted the flaps....Next time up will be no flaps and > I'll see what the climb rate is them.The Jab is the A-2200,solid > lifter 85 hp engine...ser # 1228. > >chris ambrose >m3x/jab > > >Read this topic online here: > >http://forums.matronics.com/viewtopic.php?p=243161#243161 > > >Checked by AVG - www.avg.com >05/08/09 11:43:00

    While it makes little difference as long as the runway is decent, I find one notch on takeoff gets me off the bumps earlier (John's meadow muffins?). As soon as I have established a reasonable stability I ease them off for the better climb rate.
