Since you have been setting the lengths of the pushrod as mentioned,
the linkage should be centered well as described below.
Centering
1. The levers should be as the drawing below while centering the
collective pitch stick.
2. Parallel the flybar, the main blades should be at 0 degree and the
swashplate should be level.
SETTING UP MAIN ROTOR COLLECTIVE PITCH ANGLE
Minimizing
1. Place the collective stick at low end.
2. The main blades should be at 10 degree and the swashplate should
be level.
Maximizing
1. Place the collective stick at high end.
2. The main blades should be at 10 degree and the swashplate should
be level.
NOTE:
1. The steps above define the limits of the collective pitch setting.
2. The setting of the maximum collective pitch depends on your personal
flying skill and style. Too much collective pitch could overload the
ESC, motor and the battery. And it will reduce the flying time also.
The following is the setting up data of pitch curve and throttle curve
for your reference only. Please ask experienced pilot to help you if
you have never done this before.

It is recommended to use a Heading Hold Gyro. With a Heading Hold
Gyro, you may not use the trim and the revolution mixing function of
tail control.
First, choose the length of the tail servo arm referring to the manual
of the Gyro. You may try 10.5mm as the starting setting. Then mount
the servo arm for the moment and check the movement of the tail
servo:
1. While giving the right rudder control, the servo arm should move
forward.
2. Rotate the helicopter with your hand counterclockwise, the servo
arm should move forward.
TAIL CONTROL AND GYRO SETUP
After making sure of moving direction of tail servo, you have to mount
the servo arm in the correct position. Please reset the receiver power
and do not move the helicopter. While the tail control stick and trim
are centered, mount the servo arm vertically. Next, two points may
be your concern:
1. The traveling limit of the tail servo may not go beyond the mechanical
movement.
2. The tail servo horn should be vertical while the tail rotor are at 0
pitch or with a little offset to the right.(Referring to the photo below)
Note
1. To find the traveling limit, you have to adjust the Gyro referring to
its manual.
2. To adjust the pirouetting speed of the helicopter, please use the
”Travel Adjustment” or the ”D/R & EXP” function.
The mini Titan E325 is an electric RC helicopter. It is strongly
recommended to use Lithium Polymer Battery. Please refer to the
following information and precaution:
1. Do use a charger that is designed for Li-Poly batteries only.
2. Do not overcharge the battery over the maximum voltage of 4.2V/per
cell.
3. Do not discharge the battery below the minimum voltage of 3.0V/per
cell.
4. Do not charge the battery unattended.
5. Do not charge the battery in a flammable circumstance.
6. If you want to store the battery for a long time, store them at 3.8V/per
cell.
Please understand the information and precaution above and that you
agree to accept the full responsibility of using the battery and any injury
caused by the battery. Thunder Tiger and its duly authorized distributors
assume no liability for damage that could occur by the improper using
of the battery.
USING OF LI-PO BATTERY
Helicopters
Q: What would you check when the helicopter shakes during flying?
A:
Q: What would you do if there comes out a lot of noise from the
helicopter during flying?
A:
Motor, Battery and Speed Controller
Q: How to choose the motor and the pinion?
A: It depends on the battery and the motor. The following is the formula
of how to calculate the wanted head speed.
Motor RPM = Motor KV x Volt(3.7V) x Series x constant (0.8)
Head Speed = Motor RPM / Gear Ratio
Gear Ratio = 150T / Motor Pinion
Example:
We choose TT OBL 29/35-10H brushless motor.
IF using a 3S(11.1V) Li-Po battery, the motor rpm should be
3500KV x 3.7V x 3S x 0.8= 31080 rpm
And we expect to have the head speed of 2600~2800rpm
31080 / Gear Ratio = 2800
Gear Ratio = 11.1
TROUBLE SHOOTING
Are the main blades out of track?
Are the paddles out of track?
Are the main blades well balanced?
Are the paddles well mounted at the same distance from the
rotor shaft?
Is the spindle or the flybar bent?
Is the main shaft bent?
Is the main rotor hub damaged?
Is the motor well installed and is the shaft of the motor bent?
Is the tail rotor shaft bent?
Is the tail rotor hub damaged?
Do all the ball bearings work well?
a. Please check the gear mesh between the main gear and the
motor pinion. If there is too much gear mesh, it would generate
a lot of gear noise during flying.
b. If the tail drive belt is too loose, it will bring about some noise
and may cause the failure of tail control.
c. Check the linkages and control system of main rotor and tail
rotor to make sure every linkage is working correctly and not
colliding with something else.
d. Check if the motor is running out of balance.
The pinion would be
150T / 11.1 = 13.51
So we choose 13T as the motor pinion.
IF using a 2S(7.4V) Li-Po battery for long time hovering, the motor
rpm should be
3500KV x 3.7V x 2S x 0.8= 20720 rpm
And we expect to have the hovering head speed of 2100rpm
20720 / Gear Ratio = 2100
Gear Ratio = 9.87
The pinion would be
150T / 9.87 = 15.20
So we choose 15T as the motor pinion.
Q: Which motor and speed control is recommended?
A: The TT OBL 29/35-10H brushless motor(No.2381) and the ACE
BLC-40(No.8041-H) speed control are recommended.
