Hi Jordi,
Excellent report. I flew 4 times the day before yesterday. You are correct on rudder sensitivity and conclusions with CG forward. With the contra the rudder is even more sensitive. I will try your suggestions next time I fly moving CG back. In my case with the contra looks like I need to install fences in the stab. However I am going to try your suggestions first. I notice that canalizer is not that rigid. I am planing to do something so does not move that easily. Have you notice that?
Thanks,
VB
