I finally flew my extra 300, I had personal issues with my tt.1.20 , but we finally get along.
A perry pump gave me a hand.
The airplane flew as expected , easy with not bad habit. I managed to do some rolling circles , well , to be fair , they were kind rectangular....
Regarding the 4*120 LG, It works perfect and looks neat, but you need to make some changes in the fuselage, not big deal.
