PRECAUTIONS
Your Micro B-25 Mitchell should not be considered a toy, but rather a sophisticated, working model that functions very much like a full-size airplane. Because of its performance capabilities, the Micro B-25 Mitchell, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.
- Operate the plane according to the instructions. DO NOT alter or modify the model. If you make any modifications, you void your warranty.
- Test the operation of the model before each flight to ensure that all equipment is operating properly and that the model remains structurally sound.
- Fly only indoors or outdoors on very calm days (with wind speeds less than 5mph) and in large open areas free of trees, people, buildings, or any other obstacles.
- Although the Micro B-25 Mitchell is designed to be easy to fly, it is not for the first-time pilot. We strongly recommend getting assistance from an experienced pilot for your first flights. If you're not a member of an R/C club, your local hobby shop has information about clubs in your area whose membership includes experienced pilots. You can also contact the National Academy of Model Aeronautics (AMA) which has over 2,500 chartered clubs across the country. Instructor training programs and insured newcomer training are available through any of these clubs. Contact the AMA at the following address or toll-free phone number:

TTX403 FUNCTIONS

TX-R ONLY: POWER ANYLINK OR A TACTIC 2.4GHZ TRANSMITTER
AnyLink must be in Normal Mapping (1 Beep) when Futaba®, Hitec® or Tower Hobbies transmitters are used with Tx-R aircraft. If using a Spektrum® or JR® transmitter, AnyLink must be in Alternate Mapping (2 Beeps). To change the mapping, consult your AnyLink instruction manual.
All trademarks are property of their respective owners.
LINKING TO MICRO TX-R AIRCRAFT
Micro Tx-R aircraft include a receiver that auto-links to a Tactic transmitter. Once the receiver is powered, it will link automatically to a present and compatible Tactic SLT 2.4GHz signal. Please follow these steps to safely link your transmitter and aircraft the first time.
- Always power the transmitter or AnyLink first.
- Make sure the throttle stick is down.
- Plug in the battery to the aircraft.
HELPFUL TIP: If you are going to fly with a group, pre-link your transmitter and receiver prior to arriving at the flying location. This must be done in an environment free of Tactic SLT 2.4GHz signals. Pre-linking ensures that familiarity is established between your transmitter and receiver. Familiarity guarantees that as long as your transmitter is powered first, your receiver will link to your transmitter regardless of the other compatible signals in the environment.
INSTALLATION AND REMOVAL OF THE LIPO BATTERY
Keep hands clear of the propellers during battery installation and removal.

Remove nose cone. Use two fingers to secure connector during battery installation and removal.

Press battery into place to secure.

Replace nose cone.
Disconnect and remove the battery after each flight by holding the battery lead with two fingers and removing the battery from the lead with the other hand. Do not yank or jerk the battery from the aircraft. This could dislodge the RX board from the Micro B-25 Mitchell.
CHECK THE CONTROL SURFACE DIRECTION

Left stick moves left, rudders move left, causing the aircraft to yaw left. Nosewheel points left. Right stick moves left, left aileron moves up and right aileron moves down, causing the aircraft to bank to the left.


CENTER THE CONTROL SURFACES

Before flight, center aileron control surface with aileron trim adjustment.

Before flight, center elevator control surface with elevator trim adjustment.

Before flight, center the rudder control surface using the rudder trim adjustment.
REVERSING THE CONTROL THROWS
If you ever need to reverse the control throws, follow this simple procedure.

CAUTION: Unplug the battery from the model before attempting to reverse the control throws.
Press and hold one of the corresponding control surface trim buttons and cycle the power off and then on to reverse any control surface direction. You will hear a "Beep Beep Beep" sound.
ARMING THE MOTORS
Keep hands and onlookers clear of the propeller during arming and operation.

Switch on the transmitter and position the throttle control stick in the low or minimum position. Plug the battery into the plane.

Raise the throttle control stick to the maximum or high position. You will hear a "Beep" sound.

Return the throttle control stick to the minimum position. You will hear a "Beep Beep" sound. The motors are now armed and the propellers will operate if the throttle stick is raised.
ADJUSTING THE RUDDER AND ELEVATOR LINKAGES
To alter the center position of the rudder and elevator control throws, follow these steps. Be sure to unplug the battery from the model before attempting to mechanically adjust the linkages.

CHOOSING A FLYING SITE
5 minute flight times (outdoor) 8–10 minute flight times (indoor)
RANGE CHECK

![50' [15 m]](/content/2026/06/1323389/images/da63befe3840e153ee204a2e266b2314863cfc8031b5e61555643a07759e3f70.jpg)
FLYING THE MICRO B-25
If at any time during operation, the controls or propellers become jammed or unresponsive, reduce the power to the propellers and land. Fix the problem before attempting to fly.
Take off (or hand launch) heading directly into the wind.
NOTE: If you hand launch, you can remove the landing gear by gently pulling the landing gear wires straight out of the mounts. When flying without landing gear, land on grass only to minimize damage to the motor nacelles and fuselage. Cut power to the motors completely just before the propellers touch the ground to prevent any damage.
Hand launch with throttle set at 3/4 to full power, wings level and with a slight toss (it is not necessary to aggressively throw this model to hand launch it).

Once in the air, gain altitude to allow yourself sufficient reaction time to make a correction during flight. Once you're comfortable, adjust the aileron and elevator trims one click at a time so that the Micro B-25 Mitchell flies straight and level with the control sticks centered.
Concentrate on using small aileron control inputs so the model turns without banking the wings excessively. A slight amount of up elevator may be necessary to maintain altitude going into a turn and the elevator will need to be returned to neutral when coming out of a turn to avoid gaining altitude.
It's recommended that you attempt to land before the motors lose power and don't have enough voltage to maintain altitude or the low-voltage cut-off stops the motors. Always land directly into the wind if possible. Gradually reduce power when you are close to the landing spot and when close to the ground and about to touch down, pull the elevator stick back slightly to raise the nose of the model and slow the landing speed to "flare" for landing. Unplug the battery from the model and switch off the transmitter. Allow the motors to cool between flights.
PROPELLER REPLACEMENT

To replace the propellers, first make sure the battery is unplugged. Remove the spinner by gently wiggling it and breaking the glue joint that holds the spinner in place on the propeller. Gently and carefully hold the motor shaft with needle nose pliers or a hemostat to keep it from rotating and gently unscrew the propellers from the shafts. As shown in the picture, the left propeller unscrews clockwise and the right propeller unscrews counterclockwise. BE SURE you replace the propeller with the same rotating direction propeller! The spinner can be glued back on the propeller with a small amount of aliphatic (white) glue. Allow the glue to dry sufficiently before flying the model. Gently pull on the spinner to make sure it is really glued to the propeller.
