It doesn't require any physical change to the aircraft and it's reversible. Just eight AN-3 bolts and the two AN-6's. Rick PS Trying to fix the need for the huge trim tab on the rudder I made a motor mount plate that turned the engine 5 degrees out of line to the boom C/L. Didn't make any difference whether I turned the mount over to get that offset to the opposite side. The only thing I found that did work was the lower prop rpm of the 4:1 gearbox. My Mk IIIC had a rudder trim tab that was only 6 inches long and barely had a bend in it. I kept adjusting until I needed just a touch of left rudder while climbing and a touch of right rudder in cruise.

It was trimmable but the first flight was exciting. This added new meaning to power/pitch trim with the new set up also having about twice the thrust. To be clear the reduction drive raised the thrust line 6". I flew it that way for about a year. It is best to keep the trust line as low as possible because it flys better. I wouldn't be concerned about a 1.5 inch change. Also consider that the prop to boom clearance would be about the same so maybe the effective total thrust line change might be less than 1.5.

Hello Kolbrers, I am wondering if one of you knows where I can buy plastic Airfoils for my gears legs. I bought my kit third hand and I have a lot of extra tubing and other odds and ends that seem to have not relation to the kit. I have enough Airfoil for my wing struts, but the pieces for my gear legs are 10 short. Aircraft Spruce only seems to have Aluminum Airfoils available. Thanks for the help Nick Cassara Palmer Alaska N607AK almost finished ________________________________ Message 5 _____________________________________ Time: 04:28:26 PM PST US From: Pfatchantz Subject: Re: Kolb-List: Where to buy Gear leg Airfoils?
