Ok
Just got back from a local contest with my Proline.
The set up
Cloudless sky, No wind to speak of most of the time, temps in the upper 70's lower 80's.
Perfect weather to evaluate any airplane.
Flew 6 rounds of Advance and came to the following conclusions.
The Proline has Zero really bad tendencies. It's that simple. The airplane goes where you point it. Seems I pointed mine in the wrong direction a few times but that's a story for another time.
I now have about 75 flights on the airframe and it seems to be holding up just fine. It's without a doubt the easiest rolling airplane I've ever owned/flew.
I do have a few minor things to look at in the setup I'm flying it with namely a minor pitch of the nose down with application of rudder and a slight barrel roll in a vertical power on left roll. The airplane rolls perfectly coming down or in a 45/60 power off. Only a slight barrel in an up line power on roll to the left. I've no clue what is causing this or how to try to fix it. Any help would be appreciated. Maybe some differential in the left aileron setup.
I let several others fly it and shall let them chime in with their own thoughts as they see fit.
To me it's a keeper of the first order.
