I want to say, "thank you" fo= r all of the very helpful contacts I have received as a result of my pitch = trim problem on first flight.  I have been involved with homebuilt air= planes for 25 years but I have never received responses of such high qualit= y from any other group.  Some of you even went to the trouble of findi= ng my phone number and calling me.

I wanted to let you know some= additional information that I have learned.  First of all, the airpla= ne is a 235 airframe with top hinged flaps and small tail.  The airpla= ne has a O-320 and hartzell prop.  The airplane was modified by one of= the builders by eliminating the spring trim system and replacing it with a= tab cut out of the left elevator.  The tab is driven by a mac servo i= nstalled in the elevator.  Some of you have asked the dimensions of th= e tab.  The tab is 3 inches deep at the root end, 2 inches deep at the=   tip end and it is 18 3/4" in length.

We reweighed the air= plane yesterday and recomputed the CG.  I appears that the airplane is= in the center of the envelope in the condition it was during the flight.
To review the problem that we had, the airplane had sufficient el= evator power to rotate and fly level but it required a significant nose-up = pull on the stick throughout the flight.

Now, the bad news. = ; We measured, figured and refigured.  As near as I can tell, the stab= is installed on the airplane with about 1 1/2 degrees nose up incidence.&n= bsp; According to the manual, it should be 1/2 degree nose down inicidence.=   I think this explains the problem that we had.  Cutting the tai= l off the airplane and redoing it is the obvious solution but will probably= have to wait until spring.

Any other ideas?
