Begin assembly by removing and inspecting all airframe components. Carefully become
familiar with the wiring, landing gear, gear doors, etc. The BVM F-15 GO Fly is not meant to
be a primary turbine trainer. The manual assumes you already have experience with high
performance aircraft.

Installing the Horizontal Stabilizers
•Use a Phillips head screw driver to remove
the (4) screws holding the cover plate in
place.
•The elevator clamping block uses (2) 8/32
bolts. A 9/64 wrench is required to tighten
these.
NOTE: Final adjustment should be done with the
radio on.
Use the provided Template to set the neutral point
for the Elevator This will be used later as well for
surface throws.
Preparing The Wings
•On the BVM demo model we moved the
aileron linkage to a lower hole on the servo
to improve resolution. The flaps do not need
to be changed.

BVM ®2021 6 April 2021
Wing Installation
•The servo wires and light plugs are all
different. Match them accordingly. Use tape to
secure them.
Pro Tip:Use BVM Dry Lube (#1947) to allow dowel
pins, tubes, and spars to be inserted with less friction.
•The wings are secured to the fuse by
clamping brackets. You need a 9/64 wrench
to complete this.
Installing The Vertical Fins
•Connect the LED and Servo connection. One
side will have (2) and one will have (1).
•Use a 9/64” driver to secure the clamp.

BVM ®2021 7 April 2021
•Use a 9/64” driver to secure the clamp. There
is (2) clamps. One front and one aft.
Receiver, Gyro and Battery Installation
•The BVM demo uses a Cortex Pro and a
Spektrum 20ch RX. The gyro is mounted in
front of the RX. The Pulse 3600 mah RX
batteries sit on the Velcro just in front of the
Gyro.
NOTE: The air bottles are under the front tray..
CCU/ Air Fill Valve
•The CCU and Air Fill valve are mounted
under the nose cone This has been
programmed from the factory and shouldn’t
need to be touched.

BVM ®2021 8 April 2021
UAT Mounting
•The UAT has spot under the canopy on the
right side of the fuse. We routed the fill line for
the fuel system under the nose cone.
Turbine and Pump Mounting
•
•Our demo model has a BVM T-16 for
power. We mounted the Fuel Pump
on the right side and the ECU
Battery on the left. Our ECU is built
into the front cover of the engine, so
you will not see it in the photos.
Follow your manufactures guide
lines for mounting.
NOTE: The engine rails will look a bit
different on the production versions.
Turbine and Pump Mounting
•Heatsheild was used on the
inside of Turbine Hatch as added
protection. (BVM#PA-MA-1940

BVM ®2021 9 April 2021
Wheels & Brakes Preparation
•Remove the wheel retaining screw with a 2mm
driver. Use a small amount of Z-42 when re
installing.
NOTE: If you need to remove the O'Ring. Use a
sharpened wood stick to help remove the O-Ring. Don't
use anything metal. This will scratch the inside of the
brake hub.
•Use a small amount of Axle Grease on the wheel
axle. (BVM#5784)
•Use a small amount of BVM Dry Lube on the
pivot joints on your gear.(BVM1947) Also use
a small amount of Super-O-Lube on the brake
O-ring. (BVM5779) This will help the brakes
work smoothly.

Center Of Gravity
•The Center of Gravity comes pre-marked from
the factory. Verify that it is marked at 2” forward
of the front spar.
To help mark the Center of Gravity position when the
wing is in place, you can use two Buttonhead screws
on the bottom of fuse at the fuse wing joint. (BVM #

First Flight Profile
Flight Time
The BVM demo model’s transmitter timers are set for 6 min. On the first flight, land a couple
minutes early to check fuel consumption. Adjust the flight timer accordingly.
Taxi Test/Engine Run Up
A taxi test should include a radio range check with the engine running at various power
levels. Check that the wheel brakes are adequate and the stopping action is without skidding
or pulling left or right. Be sure to shake the aircraft and push fore and aft with the engine at
half power, this will help remove any trapped air bubbles in the fuel system.
Takeoff
NOTE: If a gyro is used select the off position, for first flight until gyro can be tested at a safe
altitude.
Begin the takeoff roll by slowly advancing the throttle. Maintain runway center while holding
about 1/2 stick up elevator; the F-15 will rotate when it is ready. It there is a cross wind, hold
a small amount of aileron into the wind, be prepared with opposite rudder. The aircraft does
not need flaperons, we suggest making your first flights “clean wing”.
Trim
Once in the air, find a nice cruise speed to set the trims. The aircraft should fly straight and
level when “hands off”. When the landing gear come down, a few clicks of trim will be
needed. This can be mixed in, or use flight modes to trim automatically.
Practice Approaches
Save some time at the end of your first flight to practice approaches and go arounds. It is
beneficial to become familiar with the low speed handing of the aircraft.
Landing
Landing is like most jets, “power on” during the approach. The F-15 does not stall easily, it is
best to land nose high, touching on the main wheels first.
The majority of the first flight should be spent trimming and practicing for the first landing.
Save the aerobatics and air show stuff for later flights.
RX Battery Consumption
The average flight using the lights the entire flight consumes 500 mAh. We recommend two
flights and recharge. Use this data to calculate how many flights you can achieve from your
system. The use of the smoke pump will consume more mAh per flight. 3600 mAh combined
capacity is the minimum BVM recommends.
