The PTE 72 engine
provides plenty of
power for all maneuvers,
knife-edge flight. The airplane excels at
performing snap rolls and stops instantly
when the pressure on the sticks is
released. Knife-edge-to-knife-edge snaps
were easy to perform and plenty of fun.
The Extra flies Precision Aerobatics
maneuvers well. I think it would be a
great choice for someone looking for
his or her first International Miniature
Aerobatic Club (IMAC)-style airplane.
The Extra really shines when it comes
to flying 3-D maneuvers because of its
large, effective control surfaces. Upright
Harriers are stable with no wing rock,
and it locks into Inverted Harriers
similar to a much larger airplane.

AT A GLANCE ...
It is a stable, forgiving 3-D platform
and it shows no tendency to snap or
drop a wing when slowed down. The
Extra is easy to hover, and with the
abundance of power that the PTE 72
provides, it will rocket ship out of a
hover like a missile.
I have flown the Extra with and
without the side force generators (SFGs)
installed. With the SFGs in place, the
Extra flies knife-edge in what appears
to be slow motion. The SFGs slightly
slowed the roll rate, but didn’t seem
to affect precision maneuvers. I like
flying the airplane more with the SFGs
The Extra will perform some exciting
and fast tumbling maneuvers including
Pop Tops, Crankshafts, and any other
high-energy 3-D maneuvers you want to
I really enjoyed assembling and flying
the Redwing RC 50cc Extra 330SC. It’s
a great all-around aerobatic airplane. It
flies both Precision Aerobatics and 3-D
maneuvers well, and is easy to land.
At such a light weight, any 50 to 61cc
engine would provide plenty of power,
72 would be the engine to choose.
The quality of this ARF is good. I’m
very happy with this airplane and would
recommend it to my flying buddies.
