I have flown a Gaudius throughout most of this year. Quality is excellent. It is indeed a very constant flying airplane with good rolling, stall and spin entry capabilities. I am currently flying Advance with the Gaudius and have done well with it. Vertical lines are straight up and down with a small amount (3%) down for down lines. The plane flys with very little mix. On calm days the airplane is tough to beat. Windy conditions don't cause any issues. You need very little rudder input for point manuevers or slow rolls.
The plane builds very easy and comes out very light. Strong landing gear mount if you fly from grass. Landing gear is one piece and can be mounted in about five minutes. I lost my 1st Gaudius due to unknown causes and have since built another. This one is all white with a custom paint job. (THANKS JR FOR ALL THE HELP) I used the radio set-up from the 1st Gaudius for a start on the new one. The new Gaudius needed only 2 clicks of up elevator which actually brought the elevator to a perfect trim. If your CG is correct the airplane will trim completely neutral. I believe it presents well and can easily fly all classes. The 1st Gaudius was powered with a Plenty. The new one is powered by the Hacker Q-80. Both fly almost the same. I will say the front of the Gaudius is perfect for the Q-80. Very strong! You do not need to add the firewall if you use the Hacker. In either case you will be very satisfied with the power and by the way no cooling issues. I'll try to answer any other questions you have if you PM them to me.
