Assembly
Model Assembly (KIT only)
Rudder Servo
-
Set 9g servo to neutral point and screw on Servo arm. Glue the servo into the slot on the Rudder.
We suggest the cable length is 10cm. -
Ajust pushrods length then link the Servo arm and Control horn. Model Assembly (KIT only)
-
Same procedure on the orther Rudder.
Flap and Aileron Servo
-
Set 9g servos to neutral point and screw on Servo arm. Glue servos into the slot.
Make sure the Flap servo set to correct start point and correct flap moving direction. -
Ajust pushrods length then link the Servo arm and Control horn.
Make sure the control surface level to the Wing edge. -
Same procedure with the orther Wing.
Then align all cables along the cable slot then insert into the plastic part at the leading edge of the main wing. -
Keep all unnecessary cables inside the plastic part.
Front Wheel Servo
-
Open Battery hatch then connect to RX, Lipo and drop landing Gear out.
-
Set 9g servo to neutral point and screw on Servo arm.
-
Glue the servo into the slot.
Ajust pushrods length then link the Servo arm and Front Wheel Control Horn.
Then glue the landing gear cover on.
EDF & ESC
-
Take EDF cover and ESC cover out.
-
Glue Horizontal Stabilizer Servo into the slot.
Require 1 normal and 1 reverse 17g Servo. -
Organise servo cables along the slot.
-
Install EDFs and fixed with screws.
-
Install ESCs into the ESC compartment and connect ESCs to EDFs. Do a test to make sure the power system working properly.
Elevator
-
Install Elevator on both sides.
Tighten the screws with 1.5mm hexagon key. -
Ajust pushrods length then link the Servo arm and Elevator Control Horn.
ESC & EDF Covers
- Put ESC cover back.
Secure EDF cover with screws.
Vertical Stabilizer
- Connect Rudder servo cable to extension plug.
Glue both Vertical Stabilizers onto fuselage.
Main Wing
- Insert carbon spar into fuselage.
Then install both wings and secure with screws.
Receiver
-
Connect servo cables with your receiver in the order shown.
-
Then keep Receiver and Cables in the Receiver compartment.
Pitot tube
- Install Pitot tube onto Nose cone.
Missiles and Oil Tank
- . Slide the missiles and oil tank into the rails.
Then the assembly job is done.
Flight Setup
Check the C.G.
The Center of Gravity (CG) location is 125mm from the leading edge of the main
wing (as shown) with the battery pack installed.
The center of gravity can be adjusted by moving the battery forward or aft.
Control throws
We recommand dual rate setting for better flying experience.
When taking off and landing, Elevator and Aileron in low rate will make smooth
move;
When taxing on ground, Rudder in high rate will get smaller turning diameter;
When flying in air, low rate will make flight more stable. High rate is only
for extreme maneuvering.
| High Rate| Low Rate
---|---|---
Elevator| 100%| 80%
Aileron| 105%| 80%
Rudder| 100%| 75%
Flap| 100%| 70%
Tips
Tail heavy will get Mig-25 stall and spin at low speed. So when balancing your
model, adjust the battery as necessary so the model is level or slightly nose
down. If the tail is heavy in the first flight, pleaes throttle up to keep
speed and avoid stall.
Mig-25 can lift off in short distance, so no need of flaps when taking off.
But Flaps can reduce the landing speed and distance. No necessary of Elev /
Flap compensation.
