This is likely the root of my stalled incident.
I have been communicating with EAA Tech Counsler, Larry Geiger, and I have concluded based on his information, and his experiment with the trim method I used, that the sudden pitch up that resulted in a stall was my fault.
I made the mistake of thinking that mid-way between full up and full down of the nose of the stabilator would be a neutral, in-flight position. It is not.
By having what was believed to be a 'bit' of "up" trim, there was apparently a large up trim, and upon reaching takeoff speed the system gave me what I had unknowingly asked for.
Marty just posted a good explanation of setting the trim so the indicator is placed where you should avoid my mistake.
I still have not had the FAA visit. Today I placed an order with Vans for the material I need to repair the plane...nothing technically difficult, just a lot of work. Experts that I worked with regarding the engine convince me that the gear box should be sent to a Rotax service center for checking, and that it probably wouldn't be necessary to tear down the engine, just do a dial out check. I will pull the engine to replace the lower firewall and some other sheet metal.
I hope to be in the air by fall. Thanks to all for your input. I hope this confession of fault on my part will help another builder.
