Way back when my MKIII was 582 powered max continuous cruise was 6,500, and I usually cruised at 5,800. Aircraft was propped to turn 6,500 rpm straig ht and level WOT. A couple hundred rpm increase makes a lot of difference in climb performanc e. Holding the stick in your gut sounds to me like you are still dealing with a high thrust line. A high thrust line will rob you of much hp and perform ance. Sounds like very poor performance for any model Kolb. Got a good half hour flight time between and around the rain showers today. Did a high overhead circling approach from 2,000 feet to the sod strip at Wetumpka Airport. That is fun to do in any airplane, especially a Kolb. john h mkIII Titus, Alabama 200/250 ft by the time I reached the road at the end with the stick in my lap Rick ________________________________ Message 2 _____________________________________ Time: 06:59:09 AM PST US From: "John Hauck" Subject: RE: Kolb-List: Mk III max takeoff weight Your reply struck a cord with me.Loaded,my MK3 climbs better at 2900rpm(jabiru direct drive) than it does at WOT 3150.The amount of stick back pressure drops off as well.My heaviest lift off in 75 degrees was 1205#@1100 ' msl. G.Aman MK3c Jabiru 2200a 670 hrs. Gary A/Kolbers: Takes HP to keep that high thrust line from pushing us into the ground. After many hours flying my MKIII with 80 HP, I was alarmed on my first takeoff with the 100 horse. The MKIII didn't want to break ground. I backed off the power and she came right up. Didn't take long to readjust to the bigger engine, and I never had that problem again. I believe that not only do we have the high thrust line working against us, but we also have a less than efficient engine mount configuration. The more power we have, the more the engine is pushed out of alignment with the airframe. Softer Lord Mounts aggravate this condition. I remember flying my FS with softer Lord Mounts. On one occasion, at wide open throttle, the FS would not accelerate past 65 or 70 mph. Thought I had an engine problem. I slowly started backed off the throttle. As I did, the airspeed started to increase. I very slowly increased throttle and airspeed also increased. I think the engine power was overpowering the soft Lord Mounts to the point of kicking the thrust line so far out of alignment it would not fly any faster. Now I insure I have the hardest Lord Mounts on my MKIII to prevent this from happening. I have landed and taken off from 9,927 feet ASL at Leadville, CO, at max gross weight. Although the pilot was behind the power curve, the MKIII did a good job. There is a big transition for a sea level pilot put into a 10,000 foot environment. Most of my flying out West is around 5,000 feet up to 14,500 feet. The 912ULS and the MKIII perform well. Flying out there every day, one soon adjusts to high altitude flying. Also, local flying is done primarily with an empty airplane. When I load up to take a long cross country it takes a day or two to become adjusted to flying a heavy airplane again. Then that becomes normal. john h mkIII Titus, Alabama - Watching the rain drops fall on a warm, wet, and foggy Monday morning. ________________________________ Message 3 _____________________________________ Time: 12:47:29 PM PST US From: "Ron @ KFHU" Subject: Re: Kolb-List: Everglades flight Great video can't wait to complete my move to FL. One question which is the most friendly airport for Kolbs with the cheapest enclosed hanger in South Florida. I am planing of moving to Fort Lauderdale so I can work out of KFXE, but anywhere I can store the Kolb folded or otherwise till I can finish it would be good. I am also thinking of selling it as I am too busy to work on it in a reasonable pace not sure what is the going selling price for a mostly completed M3X with a Suzuki 1.3 16 valves DBL OHC motor. The T hangers at KFXE are too small for the M3X to store with the Beech Sierra. Ron @ KFHU Heading to FLA soon. ============================================ ---- Watkinsdw wrote: Hi, Gang, I tried a very low tech video with my phone in one hand and the stick in the other yesterday.

If it weren't an option, I'd consider Airglades at Clewiston, on the SW side of Lake Okeechobee. Good t- hangers w/ hydraulic doors go for $225/ month plus tax ($250 in all.) They have a good paved runway plus a grass strip (my preference.) Let me know when you arrive!

I live west of there and make it a point to stay clear of Airglades when fl ying in that area any more. I have been in there both by air and driven and they are not the friendliest persons when it comes to our type aircraft.

Before that I spent a good part of the morning cleaning and balancing it. Put the WD prop protractor on my prop and measured it before taking it off, then set the new prop the same. Wouldn't get over 5850 in climb or 6100 flat out. Cylinder head temp on #2 set off the alarm so I had to keep the engine at 5600 rpm in cruise to keep the CHT at 268 and keep that annoying red light from flashing. That stuff they teach you about loading up the engine is true. Got back to the house and started re-pitching the prop when friend, EAA Chapter 88 president, and Airbike Ace Paul Fiebich landed and taxied up. Finished up torquing the prop bolts as he was getting ready to leave so I followed him out. Now I get 6250 in climb and 6450 flat out. CHT's are down, EGT's are acceptable and I got 200 more fpm for my effort. Now she climbs at 800 fpm. No free lunch, she's a 68 mph IAS airplane now at 5800 rpm. But, she's a ball to fly now. I wish she were mine, I know there's 100 lbs. that could come off her and that would work the same wonders for her that taking 70 lbs. did for mine. For those of you out there building, resist the temptation to add, add, add. As Burt used to tell the LongEZ builders, if you want to add something to the airplane throw it up in the air. If it comes back down, it's too heavy. Make 550 lb. the maximum weight you will tolerate. My Mk III at 535 lbs. is a kick to fly. At 610 it was a slug no better than a Cessna 150. When I rebuild her I am going to get her to 500 lbs. like Homer intended. We have had the most beautiful January I've ever seen here in Kansas and I've gotten this Mk IIIX to fly pretty good for a fat girl. :-} Rick Girard On Mon, Jan 9, 2012 at 8:56 AM, John Hauck wrote: > > > Your reply struck a cord with me.Loaded,my MK3 climbs better at > 2900rpm(jabiru direct drive) than it does at WOT 3150.The amount of stick > back pressure drops off as well.My heaviest lift off in 75 degrees was > 1205#@1100 ' msl. > G.Aman MK3c Jabiru 2200a 670 hrs. > > > Gary A/Kolbers: > > Takes HP to keep that high thrust line from pushing us into the ground. > After many hours flying my MKIII with 80 HP, I was alarmed on my first > takeoff with the 100 horse.
