2 channel (w/o ailerons) works great. You'll never see a aileron-less
model without dihedral (I understand swept wings work too but I've never
seen that).

single channel works too - how does one do a loop with rudder-only?
Quite well thank you.

Acrobatic R/C with a normal configuration a/c are often straight winged
or close too it. That's to isolate the function of the rudder so it
causes yaw only. Works pretty well except for some effects from
fuselage blanking and such.

But that's when R/C aircraft were mosting just trying to model full
scale aircraft. That balloon was busted a long time ago. What is this?

I know a guy with a Yak-52, and I've noticed what looks like an almost
complete lack of dihedral on its wing. I suppose that has a lot to do
with its stability (or lack thereof?) The Chinese version (Nanchang)
has dihedral starting on approx the outer 1/3rd of its span IIRC.
