1. This manual will help you assemble your

B-25 Mitchell. Let’s start with the

installation of the brushless motors. Plug

the three motor wires into the three ESC

wires. Do not worry about the plug-in

order; we will check motor rotation in a

later step.

2. Feed the ESC and motor wires back into

the engine nacelle and slide the motor

onto its motor mount.

3. Tighten setscrew with 1.5mm hex wrench

to hold the motor in position.

4. Set the two engine cowls aside till a later

step.

5. Locate the various Y-connectors. See

photo for identification. The triple

connector is for the retracts (Ch. 5). The Y

that does not have the signal wire is for

the lights.

6. Photo shows the root end of a wing panel

and identifies the various connectors.

7. Locate the triple connector and plug in

one leg to the connector labeled “5”.

Please make sure to correctly orient the

signal wire on the connectors.

8. After plugging the wires together, tape the

connection with clear tape to prevent them

from disconnecting.

9. Locate the fuselage and apply a bead of

glue to the inside of the main wing

opening.

10. Apply glue to the root end of one main

wing panel.

11. Feed wires into the fuselage at front of the

wing opening and insert the wing into the

fuselage. Make sure that the wing is fully

seated into the opening. When the wing is

in the correct position it will look like the

photo, the flap line will be adjacent to the

fuselage.

12. Insert the wire wing stiffeners from the

other side of fuselage and repeat the

gluing process for the second main wing.

13. Again, make sure that the wing is fully

seated in the opening as shown in the

photo.

14. Locate the foam rectangle that creates

the wire cover for the bottom of the wing.

Apply a bead of glue around the edge.

15. Install the wire cover as shown in the

photo.

16. Locate the horizontal stabilizer. Please

note the orientation of the bell cranks in

the photo.

17. Insert the rudder pushrod Z-bend into the

outermost hole on the inboard bell crank

as shown in the photo. Repeat for the

opposite side of the stabilizer.

18. Place the stabilizer in position on the

fuselage and screw into position with the

long screws as shown. Note: it is not

necessary to glue the stab in position.

19. . Snug each screw in position. Do not over

tighten.

20. Attach the elevator pushrod to the control

horn in the outermost hole. After powering

up the radio system and with your control

trims in neutral adjust clevises so that the

elevators are in neutral.

21. Install the two vertical fins on the

horizontal stabilizer. A small amount of

glue can be used if desired.

22. Screw fin into position as shown.

23. Install the short rudder pushrods to the

outer bell cranks as shown in the photo.

24. Lightly glue the rear screw cover into

position on the bottom of the fuselage.

25. Temporarily install props on the motors.

PLEASE NOTE: Both left and right hand

props are provided in the kit. We recommend

that the B-25 prop rotation be setup with the

tips of the props rotating toward the wingtips

at the top of their rotation. This means that

from the pilots seat the right engine is rotating

clockwise and the left engine counter

clockwise. If either motor is not turning in the

correct direction, swap any two of the three

motor wires to reverse its direction.

26. After removing the props, install the

engine cowls. Three small black screws

are provided for each cowl and wooden

cowl mounting blocks are pre-installed on

the nacelles.

27. Make sure that the cowl in centered

correctly and the motor shaft turns freely,

then screw into position.

28. Re-install the propellers with the right

hand rotation prop on the right motor and

the left hand rotation one on the left motor.

29. Use a flat washer, lock washer and a nut

to hold each prop.

30. Screw plastic prop hub to the shaft of the

motor as shown.

31. Locate the injection molded detail parts.

Glue the cockpit air intakes in place with a

small amount of glue.

32. The fin aerial is installed on the top of the

fuselage behind the ball turret.

33. The teardrop antenna is glued in place on

the bottom of the fuselage behind the

nose gear door.

34. Make pilot holes for the gun barrels with a

thin Phillips screwdriver or length of music

wire. Install gun barrels as shown.

35. Make pilot hole for side gun blister barrel

and install as shown.

36. Install two gun barrels in tail position.

37. Using a body reamer, create holes in the

top turret to accept the gun barrels.

38. Install barrels in turret.

39. Apply a thin bead of glue to the edge of

the nose greenhouse and install on

fuselage. Use the artwork as a guide to

orientation.

40. With model on its back, mark a point that

is 2-1/2” back from the leading edge of the

wing next to the fuselage. This is the CG

for this model. All initial flights should be

flown with the CG no further aft than this.

After test and trim flights adjust the CG to

suit your flying style.

41. Install your radio receiver being careful to

plug each connector to the proper

channel.

42. Install the power Y-conn to each ESC

making sure that you plug the red-to-red

and black-to-black. Feed the Deans plug

into the cockpit area of the fuselage.

43. The flight battery is located under the

cockpit. Lift from the rear to remove. A

3-cell Lipo battery of approx. 2500mAh is

about right for size and weight.

44. Each landing gear sequencer controls

one gear door and one gear leg. The three

plugs connect with the signal wire to the

rear of the sequencer (away from label).

45. Make sure that the sequencer and motor

wires are neatly tucked away so that they

do not interfere with the landing gear

wheel when the gear is retracted.

46. When the landing gear is retracted any

wires should not obstruct the wheel.

47. When the gear is in the down position it

should lock so that it does not collapse

under load.

48. With the model upside down and your

transmitter turned ON with the throttle in

the OFF position; plug a 3-cell Lipo battery

to the Deans plug to power up the system.

Check that each control surface is working

with the correct stick movement and in the

correct direction, adjust as necessary

49. The B-25 includes three landing gear

sequencing modules, one for each gear

location.

50. The landing gear retracts at a scale like

speed.

51. Once the gear is completely retracted the

gear doors are commanded to close.

52. Each gear door closes at a scale like

speed

53. Once completely closed they are ready to

reverse the operation for landing.

Recommended Control Throws

Ailerons Low Rate 5/16" Up and Down

High Rate 1/2" Up and Down

Elevator Low Rate 5/16" Up and Down

High Rate 1/2" Up and Down

Rudder 1/4" Both Directions

Center of Gravity 2-1/8"- 2-1/2" Back from the wing leading edge at the root

Preflight

If you are new to flying R/C aircraft, or a seasoned modeler, we recommend you have a

fellow R/C modeler help you with the first flight. Some items you will need to complete

on your first preflight are:

1. Aircraft assembled correctly and ready for flight.

2. All control throws and expos are set per this manual.

3. Transmitter fully charged and on correct model.

4. Aircraft balances at the recommended location. (2-1/2” aft of wing Leading Edge)

5. Flight Batteries are fully charged and secure.

6. All electronics are operating correctly, proper direction, and secure.

7. Complete a radio Range Check per your radio manual.

8. Balance propeller and make sure it is secure.

9. Wait for a calm or light wind day for first flights.

10. If you are new to R/C flying, consider having an accomplished flyer make the first

flight and trim the aircraft. A buddy-box training system is also very helpful.

Flying

The B-25 has very good ground handling character due to its wide stance tricycle

landing gear. This makes taxi and take-off an easy task. Point the nose into the wind

and smoothly advance the throttle, use a little rudder to maintain a straight line and as

the speed increases ease back on the elevator for a smooth lift off. Once the gear are

clear hit the retract switch and watch the gear slowly come up and then the gear doors

swing closed. The flight is scale looking with moderate speed, climb is strong; the two

counter rotating props provide a lot of thrust without the associated torque. Mild

aerobatics can be performed, loops, rolls and inverted are possible but not particularly

scale. Touch-and-go’s are a joy, set up on the runway and drop the gear, ease back on

the throttles and lightly touch down, feed in full throttle and ease back into the sky.

Landings are best accomplished by maintaining a little power completely through the

touch down. The working position lights allow you to continue flying right up to dusk.

Happy Landings!
