Diamond/FMS F4U Corsair
e Diamond Models F4U has scale, working
oleo struts with large, rubber wheels. is
makes it possible to fly from most surfaces with ease. is being said,
this plane is no “park flyer.” With almost a 70-inch wingspan, this model
takes up some space. It displayed no tendencies to want to nose over at
any time, which is a nice feature in any warbird. e only thing to watch for
while on the ground is the P-factor during takeoff. I found myself using
most of the right rudder while in high rates on takeoff. At no time did I feel
like the plane was out of control, but it is definitely something to be aware
of before taking this plane to the skies.
General FliGht PerFormance:
I have to admit that this plane surprised me a little. From the very
beginning, I was a little skeptical of a 67-inch-span, 12-pound, all-foam
model. Once I got this plane in the air, all skepticism was gone. e
included powerplant and 4-bladed propeller had plenty of power and
provided very scale appearance and performance.
Stability: Once I got the model airborne and trimmed out, I noticed how
“locked in” it felt. I never noticed the plane wanting to snap out of a turn at
either mid and full power.
Tracking: Tracking was solid on the Corsair. I was able to point the plane
where I wanted it to go and it would get there without much input from
me. Of course, this is no pattern plane. However, it excels in the warbird
category for tracking.
Aerobatics: Aerobatics is the one area of flying that could ding this
plane’s performance. Rolls were very axial and there was plenty of aileron
authority to bring the plane around fairly quickly. Loops require some
forethought to make sure you have enough energy to get over the top.
e one thing that may help when it comes to aerobatics would be a
higher performance, 2-blade propeller. 4-blade props are not known
for having excess power, so this is the price that is paid for some scale
realism.
Glide and stall performance: With the power off, this plane slows down
very nicely. ere was no indication of wanting to drop a wing or any
loss of control authority. For landing, I deployed half flaps and made sure
to carry a little airspeed until I made the end of the runway. Once I was
there, I simply cut the throttle and flared for touchdown. Once the wheels
were on the ground, I released some of the back pressure and the model
stayed down and rolled out beautifully.
Pilot DebrieFinG
is plane performs exceptionally well for any class of warbird. I was very
relaxed and comfortable flying this model. If you are looking for a first
warbird, I would highly recommend contacting Diamond Models.
In the Air
Everything you need to complete the
model is included in the box except for
your 6S, 4000mAh battery, charger, and
receiver for the radio of your choice. This
includes a very nice set of electric retract-
able landing gears, electric retractable tail-
wheel, a pre-finished canopy with pilot,
scale 4-blade propeller, all the servos, con-
trol horns, and linkages
After building and flying this model, I
would recommend it to anyone with inter-
mediate piloting skills and any level of
building experience. The model is assem-
bled with almost no use of glue and most
everything is secured with the included
screws. Even though this is a scale model,
it displayed very solid flight characteristics
that anyone with a little low-wing, tail-
dragger experience should be comfortable
soloing.
UniqUe FeatUres
The first thing I noticed when unboxing
this model was its completeness. The part
that stuck out the most was the hinging.
All surfaces have molded hinge lines. This
seems to be very strong and keeps all con-
trol surfaces aligned with their stationary
counterpart.
When I got the wings out of their pack-
aging, I was very happy to find that the
electric retracts was already installed and
ready for flight. Also, the 2-aileron and
4-flap servos were pre-installed as well.
This definitely saves time when complet-
ing your new model. All that needed to be
done to complete the wings was to mount
the six control horns (which have pre-
molded placement indents in the surfaces)
and connect the control surfaces to the
ailerons using the included pushrods and
servo horns.
