Thanks Richard. Now I have to learn to fly that thing without making a merry widow of my wife :)
Last evening, after removing the turbo and making bunch of improvements including IVO electric 68" prop, I loaded the minister of finance (she ordered me ) and went to make three high speed taxis with the new prop. What a kick in the back! These props make big difference on take off by allowing you to develop high rpm from the start. Since I ordered this prop for my turbo installation, I'm a bit low on the rpm. Will try it by converting the same prop (68" with pitch 45-105 range) to two blade. My prop calculator http://www.hoverhawk.com/propspd.html tells me for best thrust I must spin the engine at least to 6500 - 7000 rpm. I'm about 1000 rpm short right now. I was surprised to see my manifold pressure go past 30". i did not understand why my TAS stays at 18 when the plane is not moving, but goes up with the forward speed? I was expecting to see it at zero?.

Hi Buly and Ernest,
you guy's can only be proud with your plan-built projects. You are way ahead of us kit builders as far as dedication is concerned in addition of everything else. I have watched several Easy builders over the years, and at my visit to Ernest last Christmas, I realized again how much difference there is between kit and plan when Ernest explained to me how he managed to manufacture SS channel because it could not bought anywhere. I think plan-builders are the creme of the experimenters community.
FWIW.
