You can easily get the Opterra airborne in 15 minutes, and flying the Opterra is
just as easy. My recommendation? Get an Opterra, take it to the field, and have
a blast. J
well, and I never felt as if it were lacking control.
The integrated vortex generators really do
Tracking: Being a blended-wing model with
zero tail moment, the Opterra is not designed
to track like a pattern plane. The set of vertical
fins near the fuse and the winglets do a great
job of minimizing yaw drift, and this is probably
one of the best flying-wing designs I have
ever flown. The Opterra goes where you want
it and requires little input, especially with the
Aerobatics: I performed some loops, rolls,
vertical figure-8s, and inverted flight, and all
were fairly effortless.
Glide and stall performance: I must say that
I am not even sure the Opterra will stall. Even
with the motor off and flying at a walking
pace, the Opterra just keeps floating along
with what is perceived as zero sink. We have
a small hill on final approach at my field, and
after cutting the motor on the downwind leg
and staying less than 5 feet off the hill, the
Opterra still glided the entire length of the
800-foot runway, only for me to power up and
go around. Its glide and stall performance are
What a fun plane to fly. It’s large and easy to see,
and it’s stable and controlled at all speeds—it’s
just plain fun. One thing I would like to mention is
the launch of the Opterra: I don’t like launching a
pusher plane with the motor running, and with
the Opterra, it really isn’t necessary. With SAFE
mode engaged, I gave the Opterra a firm toss
and applied the power after it left my hand, and
it displayed very little sink and I had no fear of it
hitting the ground.
Covered servos and linkages really help streamline the airframe. The PNP version comes with a AS3X-enabled AR636
receiver installed and ready for flight.
The preinstalled folding propeller is ideal with the included power system. Note the air vents on the spinner—
a nice touch.
A 3S 2200mAh battery provides low wing loading and
plenty of flight time (up to 30 minutes!).
