perform better with more elevator defl ection and a farther
forward C.G. while other planes prefer a further aft C.G. and
less elevator defl ection. Elevator to fl ap mixing can be used
on airplanes with marginal wing area, and some planes won’t
stall so elevator to spolieron mixing will be needed.
ROLLING HARRIER
Once you get comfortable with the up-right harrier, it’s time
to work rolls into the mix. From an up-right harrier, add in left
aileron and change from up elevator to down elevator when
inverted. If you are comfortable with four point rolls and slow
rolls, inputting rudder on the knife edges can improve the
maneuver considerably. To turn the model, simply input the
elevator or rudder a little sooner or later in the rotation. It’s all
a matter of timing.
PINWHEEL
Climb vertically and bring the model to a vertical hover, but do
not stop long enough to let the torque pull the model around
(climbing or sliding slightly will not be noticeable to spectators
but will keep air fl owing over the ailerons and provide you roll
authority to stop the torque). When the model is hanging,
rock the plane left with rudder, then apply full throttle and
full right rudder and hold both, completing 3/4 of a VERY
tight Knife Edge Loop and fl ying out Knife Edge. When done
correctly, the plane pivots around the wing tip in a very small
area. This maneuver can be done either direction.

Great Planes Reactor ™ 3D GP/EP ARF
Precision pattern plane – or all-out 3D aerobat? You decide.
Glow power – or electric power? Your choice – and the
performance is outstanding whichever you choose. Pure,
no-compromise sport design is one reason; a mid-wing
design and a thin, 9% airfoil are two more. Plus, the light,
strong wood airframe that resists 3D stresses is already built
and factory-covered, which cuts assembly time to just 5 to 6
hours. GPMA1021
ElectriFly Yak 55 EP 3D ARF by Great Planes
• High alpha flight, Parachutes, Blenders, even Walls – there’s
virtually no limit to the Yak’s aerobatic capabilities!
• Sized to fly in a park, sports field – almost anywhere!
You don’t need expensive brushless motor systems for 3D
electric aerobatics. The Yak’s enormous control surfaces
and full flying stabilizer offer impressive maneuverability
and hovering potential with the powerful, included 280-size
brushed motor and 5:1 gearbox. Its low parts count and
easy final assembly will have this aerobat flight-ready in just
2 to 3 hours. The durable, lightweight EPS foam airframe
features a high-vis, preapplied trim scheme. An included
“prop saver” allows the prop to deflect back upon landing,
and is compatible with APC or GWS prop hubs. GPMA1190
