freely with just a small amount of left and right "play". Once in
position, firmly tighten the setscrew in the wheel collar. Repeat this
process with the remaining wheel.
The wing assembly is now complete and ready to use. Set it aside
for now.
MOTOR, RECEIVER, & ESC INSTALLATION:
The following parts are not included in your kit. These will be
required for the following assembly steps:
❑
Motor of choice
❑
Mounting bolts & washers for your specific motor
❑
Prop adaptor for your specific motor shaft
❑
Electronic speed control (ESC)
❑
Receiver
❑
3" or 4" of Velcro
®
for mounting the receiver & ESC
Note: The metal motor mount in the Bf-109 has been designed to
accommodate the front mounting of most 35 mm diameter motors.
The small holes give a general location for the tapped holes
in the front of your motor.
Enlarge or slot them as needed
to accommodate your specific motor.
We have used Himax
HC3516-1130 and HC3522-0990 motors with the proper speed
controls, props, and 3S1P LiPo 3300 mAh batteries in the
prototypes and have been very satisfied with the performance and
duration of these setups. We will show the HC3522-0990 in this
manual as a typical motor installation.
❑
1) Feed the motor wires through one of the openings next to
the front motor mount plate and position the motor up to the back
side of the front mounting plate. Bolt the motor to the mounting
plate using the appropriate bolts and washers for your specific
motor. We always suggest using a non-permanent thread-locking
compound for these bolts, such as Loctite
®
"Blue". This simple
precaution works very well to keep these bolts in place under
vibration.

2) Attach the gear doors to the inside of the gear legs using
the metal clips, M2 x 8 mm bolts, M2 nuts, and M2 washers. Note
that the bottom edges of these doors are made with two distinct
angles. The more highly angled edge should be oriented toward
the rear of the wing to providing better ground clearance.
❑
3) Insert the wires into the landing gear blocks in the wing, with
the legs and doors offset to the front leading edge of the wing. The
wheel axles should be close to the leading edge when viewed from
above and aligned with each other in a straight line or a slight toe
in position. It might be necessary to slightly "tweek" the axle wires
to achieve alignment. If so, do this now.
❑
4) Once satisfied with the axle alignment, secure both landing
gear wires into the wing bottom using the four plastic retaining
straps, as shown. Hold the strap in place and mark its two hole
locations onto the surface of the wing. Use a 3/32" dia. bit to drill
pilot holes for the mounting screws. Repeat this process for the
remaining landing gear straps. Secure the straps in place with
T3 x 8 mm PWA screws.
5) The main wheels are now installed and secured. Slide a
plastic bushing over the axle wire, all the way to the bend. Slide
the main wheel in place onto the axle, followed by the wheel collar.
The wheel collar should be positioned to allow the wheel to turn
