(Charlie England) ________________________________ Message 1 _____________________________________ Time: 01:07:40 PM PST US From: Charlie England Subject: Kolb-List: Twinstar Mk I weight & balance? Getting ready to weigh the Twinstar. Anyone have a clue what part of the airframe can be leveled, to put it in flight attitude? On this one, leveling the top tube gives about 5 degrees positive AOA on the bottom of the airfoil. Does this sound about right for doing W&B? Was there ever a preferred datum point on these old planes? Thanks, Charlie ________________________________ Message 2 _____________________________________ Time: 01:29:33 PM PST US From: George Helton Subject: Re: Kolb-List: Twinstar Mk I weight & balance? Charlie, I=99m pretty sure the wings leading edge is the preferred da tum. On a level surface the bottom of the wing should be set 8 or 9 degrees by raising or lowering the tail. It=99s looking pretty nice in your pict ure. George H.

Thanks, George; I appreciate it. My a&p buddy was guessing at 2-3 degrees of actual angle of attack, so I'll need to adjust a bit.
