I've got about 10 hours on My Kolb now. First flight was in July. It's an Xtra with 912s engine and 3 blade Warp prop.
I set up the wings, tail and rudder trim tab per TNK's recommendations. It flies great at cruse with only finger tip pressure needed on the stick.
I also set up the prop per John Hauck's recommendation and it's right on the money. Full throttle climb is 5450 rpm. I did a number of speed runs with the gps and the cruse speed at 4800-5000 rpm is about 82 mph. I have a UMA airspeed indicator and it reads about 15 mph high at cruse and about 9 mph high at stall. I have changed the static and pitot locations with no change so I'm sure it's the indicator. I checked the net and that seemed to be a common complaint with UMA. At least it's very consistant. The actual stall at 1 notch of flaps appears to be in the mid to low 40's.
Rick Neilsen said that landing like a Champ or Cub would be a problem with the Kolb. He was right on. I have about 50 hours in a Cub and without some instruction I'm sure I would have some bent gear or worse. When you flair (I think level off is a better term for the Kolb) you do it just a foot or two about the runway and it only takes an inch or two movement on the stick. It's not at all like a nose high flair, stick back in your belly like a cub. If you do that in a Kolb you'll immediately 20 feet high and starting to stall. Just hold it level and it will slow down and settle in. It is no where as touchy as a Cbe ub. If you land a little crossways it actually tends to straighten out on its own. You still have to work the rudder to keep it straight but it's much easier than with a Cub. Get some instruction in a Kolb before you fly!!!
