Performance should be okay at a guess.
My trimming field is the local quite large park for these sort of things, so it's 2 or 3 hundred hand turns maximum with short DT. It is a bit heart in mouth at times though, and it needs to be very calm of course.
About all it needed was for the wing to be moved forward then it glided nicely.
RH thrust is built in and tail tilt to send it left when the winds run off.
At a guess on lots of turns it might need a little more down thrust??????

It flew okay Jim on low turns, but it got sold just before Christmas with a few other things.
