Did you made first fly , how she fly ?

[ArgyrisGiannetakis]

Hallo dear Rumen!Not yet .She is sensitive! and my mistakes also!My set up after the first test from November has change in some points.It was all ok then but little sensitive with canard.So I change little more the Cg front from 19.5 to 18 % and I change the down thrust also from 2.5 to 1 .These two change a lot of and at take of run she never get the nose up.The steering strut collapse  and stop with some damage at the and of runway.I had to fix the half wing the left canard and the front strut.I made the wrong decision to change everthing all together and not step by step.You can see some photos from my friends here https://www.aeromodelling.gr/ForumS/index.php?topic=42386.15
I believe I will be ready in a month for new test.

I see !
I think you can try  for the first fly help from gyroscope.
I wish you success !
