After removing the large hatch on the top of the fuselage, there is plenty of room to
access the radio and fuel systems.
I throttled up for the maiden flight and the
Valiant was airborne in only a few seconds. Its
climbout was nice and stable, and it only needed
a few clicks of trim. By the time I had flown once
around the field, the Valiant was dialed in and
I spent some time on low passes to grab some
flight shots. After those were done, it was time to
have some fun, and fun was exactly what I was
having! Not knowing quite what to expect, I was
pleasantly surprised by the Valiant’s wide flight
envelope. Under power, it’s quite agile and capable
of basic International Miniature Aerobatic Club
The ailerons offer good control, but the rolls are
slow, no doubt in part because of the long wings.
The elevator is quite sensitive and I found myself
dialing in more exponential during subsequent
I spent some time seeing how effective the
flaps were. At half flaps, the Valiant slows nicely
and I needed to feed in a little down-elevator to
hold level flight. At full flaps, the model will slow
down to a walking speed when the throttle is
at idle. Even at this super-slow speed, it is quite
controllable and shows no tendency to tip stall,
which makes it perfect for spot landings.
On the next flight, I explored the more
aerobatic side of the Valiant. As I mentioned, it is
capable of basic IMAC maneuvers such as rolls,
loops, point rolls, hammerheads, etc. Snap rolls can
be done, but it requires holding it in the snap until
the second roll for the “snap” to kick in.
Taking the Valiant up to altitude, I explored
the stall and spin threshold. During stalls, I had a hard time
getting it to do anything other than continue flying with
somewhat mushy controls.
Spins have a slow, almost majestic look as this large
model slowly tumbles vertically downward. Recovery was
instantaneous. I simply returned the controls to neutral, then
pulled to level flight.
At the beginning of this review, I wondered how to
categorize the Valiant. As you can see, it really isn’t one
particular type of airplane. With good low-speed stability and
controllability, it is a nice intermediate trainer, or a great first-time Giant Scale model.
It has a good glide ratio because of its long wings, but if
you move the throttle stick up slightly, the Valiant transforms
into a capable aerobatic performer. Yes, it will require some
cross control for knife-edge passes and point rolls, but that’s
to be expected.
It has been a while since the Valiant’s maiden flight and I
have not had any problems with the aircraft. The Evolution
engine has been broken in and provides plenty of power. For
a 30cc aircraft, its size gives it quite a presence at the field.
Horizon Hobby also offers two landing gear options for the
Valiant. One is a float kit for all of you water fliers out there.
The other is a tundra-style landing gear with large wheels for
bumpy landing strips.
