GET THE MODEL READY TO FLY
Identify Your Model
No matter if you fl y at an AMA sanctioned R/C club site or 
if you fl y somewhere on your own, you should always have 
your name, address, telephone number and AMA number on 
or inside your model. It is required at all AMA R/C club fl ying 
sites and AMA sanctioned fl ying events and simply a “good 
idea” even if fl ying somewhere else. Write this information on 
a strip of masking tape and place it on the inside of the model. 
The bottom center of the wing also makes a good location for 
the information. 
Find a Suitable Flying Site
Find a fl ying site clear of buildings, trees, power lines and other 
obstructions. Until you know how much area will be required 
and have mastered fl ying your Sensei in confi ned spaces, a 
site at least the size of two or three football fi elds should be 
adequate – a fl ying fi eld specifi cally intended for R/C planes 
is best. Don’t fl y within fi ve miles of R/C fl ying fi elds and 
never fl y near people – especially children who can wander 
unpredictably into the fl ying area.
Know Your Frequency
CAUTION: This applies only to pilots fl ying their Sensei 
with a radio control system that broadcasts on 72MHz. 
This caution does not apply to pilots fl ying their 
Sensei on 2.4GHz.
Transmitters operating on 72MHz operate on one of 
several frequencies available. To fi nd your frequency (or 
“channel”), look at the label on the transmitter. If your 
channel happens to be the same as another model that is 
being fl own nearby (even within a few miles), one or both 
models will crash. Know your frequency and be aware of 
the frequency of other models that are fl ying nearby—
especially if you are fl ying at a radio control fl ying site. All 
fl ying sites have some sort of frequency control system to 
avoid this kind of interference, so learn how to use their 
frequency control system. Never turn on your transmitter 
until you are certain that you will be the only one operating 
on your frequency.
Perform a Range Check
As a precaution, an operational ground range test should 
be performed before the fi rst fl ight each time you go out. 
Performing a range test is a good way to detect problems that 
could cause loss of control such as low batteries, defective or 
damaged radio components or radio interference. This usually 
requires an assistant and should be done at the actual fl ying 
site you will be using. 
First switch on the transmitter, then install the fully-charged 
battery into the fuselage. Connect the battery and install the 
battery hatch.
Remember, use care not to “bump” the throttle stick. 
Otherwise, the propeller will turn and possibly cause 
damage or injury. 
To range check the Tactic TTX600 radio control system, switch 
on the transmitter and connect the motor battery to the ESC. 
Set the model on the ground and have an assistant hold the 
model. Walk 100’ (90m) from the model and while pointing the 
transmitter at the plane, operate the controls ensuring that the 
plane’s surfaces operate according to the transmitter inputs. 
Operate the motor at different rpms. Have your assistant 
alert you if the controls quit responding or move suddenly or 
erratically. If you are using a different radio control system, 
follow the instructions that came with your radio control system 
to perform a ground range check. 
If the controls aren’t working correctly or if anything seems 
wrong, don’t fl y the model until you fi nd and correct the problem. 
Make certain all the servo wires are securely connected to the 
receiver and the transmitter batteries are in good condition. 
Monitor Your Flight Time
Monitor and limit your fl ight time using a timer (such as one on 
a wrist watch or in your transmitter if yours has one). When the 
batteries are getting low you will usually notice a performance 
drop before the ESC cuts off motor power, so when the plane 
starts fl ying slower you should land.
To avoid an unexpected dead-stick landing on your fi rst fl ight, 
set your timer to a conservative 4 minutes (in most conditions 
the Sensei will usually fl y for approximately 5 minutes, but this 
can vary). When your alarm sounds you can either land right 
away, or if you are an experienced pilot you may continue to 
fl y until the motor fi nally quits. Then, glide it in for a landing. 
If planning a “dead-stick,” circle your Sensei upwind of the 
landing area until the motor quits and note the run time.
When you learn how much fl ight time you are getting you 
can adjust your timer accordingly. Always be conservative so 
the motor won’t quit unexpectedly and you will have enough 
battery to land under power.
