An innovative feature
on the Forza 700 is the
battery tray clip. Insert
the tray until the retaining
clip clicks into place.
The narrow frame
requires careful wire
routing. Velcro straps

It wanted to catch on the carbon when
I was pressing downward. I fixed this by
slightly beveling the top of the carbon
with some sandpaper, which allowed the
clip to easily disengage.
Did I mention that the Forza 700 is
sleek? Part of its sleekness comes from
the way the canopy fits precisely over
the frames. If you tend to have wires
hanging off the front of your batteries,
you may have some difficulty placing
the canopy on the helicopter.
Final Assembly and Setup
Inspect all bolts and attachment
points to ensure a safe test flight. A 700-
size helicopter demands your attention
and respect. Keep that in mind during
When determining your desired
flight time and head speeds, review the
manual’s section on gear ratio and rotor
rpm setup. I usually perform my first
test flights at lower head speeds and I
found that the estimates in the manual
were close to actual flight times.
I will be using the JR Triple-Axis
Gyro System (TAGS) Mini flybarless
control unit and the JR XG14
14-channel DMSS radio system.
Because I used both of these items with
my Forza 450, I know that you cannot
go wrong with this combination.
The JR TAGS Mini is JR’s newest
three-axis gyro system. It is an all-in-one unit and comes with a remote
receiver. The TAGS Mini provides
telemetry and allows seamless
integration with any of the new JR
The XG14 is JR’s newest DMSS
transmitter and offers the XBus
communication protocol. This is a top-notch radio at a competitive price.
Program your transmitter first.
After setting up the JR XG14, I run
a calibration with the TAGS unit that
allows it to learn the transmitter settings.
This feature provides a comfortable
transition from a standard flybarred
system to flybarless.
Verify all control settings before your
maiden flight. If the flybarless unit is
sensing in the wrong direction, the heli
could crash. The gyros should always
correct against the
movement. If you tilt
the helicopter right,
the swashplate should
tilt left. After you have
verified all settings
and fully charged your
batteries, you will be
prepared for your
The first flights on
my Forza 700 were
successful with no surprises. I flew the
helicopter at a lower head speed of
approximately 1,600 rpm. I like to start
at a lower head speed in case my gains
are too high or the aircraft fails.
The Forza is quite capable at lower
head speeds, but remains smooth when
moved closer to the 2,000-rpm range. It
has a wide performance envelope and is
suitable for pilots of various skill levels.
I would like to congratulate JR on a
wonderful helicopter design. It was an
easy, pleasurable build. The only issues
I encountered were minor and easily
JR delivers on its promise: a high-quality helicopter at a competitive price.
If you are looking for your next heli,
look no further.
The JR Forza 700 has the lines of a
Japanese bullet train and the looks of a
super model. It is sure to thrill.
