A 540 Kv brushless outrunner motor is included and is factory mounted to the airframe.
To get the correct CG, I moved the ESC to the radio bay and added a hook-and-loop strap to mount
the battery outside of its molded pocket. Note the green circuit board through which all of the
servo leads are routed.
A small piece of clear tape protrudes
behind the canopy. It acts as a grip for
removing the magnetically secured
battery hatch. Although the tab works
fine, I didn’t like the way that it looked. I
removed the tape and replaced it with a
short plastic post that I glued into place.
The post was made from an insulin
The kit includes three plastic faux
antennae that can be glued to the
airframe to further enhance its scale
appearance. I attached them with Goop.
These antennae reflect the modern
radios used on the Flying Bulls’ Red Bull
Corsair, instead of the legacy equipment
that was originally installed. The trailing
edges of these pieces are sharp. I sanded
mine to make them less of a hazard.
I linked the included AR636A receiver
to my Spektrum DX8 transmitter. The
manual provides suggested control
throws, which I followed. I also added
30% exponential to the ailerons, elevator,
I initially used an E-flite 4S 2,800
mAh 30C LiPo battery. With this pack
located in the battery slot, the model
balanced approximately 1/4 inch forward
of the suggested center of gravity (CG)
location. I flew the maiden flight with
the forward CG and quickly wished I
hadn’t. I suggest that you stick with the
To get the CG where it should be,
I moved the ESC from the motor
cowling to the radio bay. I also added a
hook-and-loop strap behind the battery
slot. This allowed me to locate the
battery farther aft. The strap also lets
me use a variety of batteries while still
maintaining the correct CG.
Flying the Corsair
It might be a foamie, but the
completed Corsair is a large and
impressive model. It looks good sitting
on the tarmac, but it looks even better in
The 14 x 8 four-blade propeller is big
and heavy, so it has more left-turning
gyroscopic effect and P-effect than
smaller, lighter propellers. Make sure
that your rudder finger is ready for
corrective inputs on takeoff. It also helps
if you avoid any large, sudden throttle
I like to hold a tad of up-elevator as
I begin the takeoff roll. This prevents
the nose from pointing down as the tail
wheel lifts and the airplane is rolling on
the main wheels. The Corsair quickly
builds speed and is usually airborne
before I hit full throttle.
As soon as the model is flying, I begin
retracting the landing gear. It has a slow,
scalelike movement. The autosequencing
gear doors are also a nice touch. It
takes roughly 10 seconds for all of the
movement to be completed. Keep this in
mind if you ever have to make a sudden
emergency landing. You may be better
off keeping the gear retracted than
landing with it partially deployed.
The Corsair likes to be flown with a
lot of power. I’m often between 75%
and full power for most of the flight.
When using the 2,800 mAh battery, I
get flights that last approximately five
minutes, with plenty of spare capacity
left if I need to make a go-around or two.
I have also flown the Corsair with 2,400
mAh and 3,200 mAh LiPo batteries.
Flight times are four and six minutes
respectively, and performance is similar
