I love this thread! I recently took delivery of a C2 kit and I've been studying every single picture you posted.

There's another thread where people are complaining about trim problems with this aircraft, particularly a pitch to the canopy in knife edge that the can't seem to trim out. Have you experienced that problem?
Could you post your starting point for the CG?

Thanks and good luck,
Scott
Hi Scott,

I waited till now after I finished the trimming process to answer your question.

Now when I have 40 flights on the plane, I can say that I am satisfied with the way the plane flies.

On the first 15 flights I dealt with that pitch to the canopy problem that you were talking about.

I had to move the C.G. from 220 mm (25% of the MAC) to 200 mm from the T.E. (31.5% of the MAC). And to increase the down thrust.

The final angles are:

Canopy floor: -2.75 degrees

Wing: -0.35 degrees

Airflow: -0.85 degrees

Down thrust: -2.15 degrees

Right thrust: 3.70 degrees

Best regards
