Secure the power and ground wires within each wing panel. Since
this airplane features foam wing panels, I cut a long, 1/16-inch-
deep slot into each wing panel and inserted the power and ground
wires into them. At the wing root, I soldered a Micro Deans connector so I could plug them into the speed controller. To keep the
installation process neat and tidy, I decided to route the wire with
the Micro Deans connector with the aileron servo lead and used a
zip-tie to hold all wires to one another.
The smoke emitter is ignited with a fuse connected to the power
wire leads. The fuse must be easily replaced because the smoke cartridges are replaced after each use. The fuse has two wires marked red
and white (white for ground line and red for the power lead). I drilled
two 1/16-inch holes in each cartridge mount for the fuse wires. After
threading two 2mm bolts in each hole, I stripped the power wire
back about 1/2 inch and wrapped the wire around the head of one
bolt. Then, I did the same for the ground wire around the second
bolt. I soldered the wing wires to the bolts to complete the circuit.
Power for smoke
The power to ignite the smoke cartridges comes from a 10-amp
speed controller for brushed motors. I also added a switch to the
power line between the speed controller and the battery connec-
tion. This prevents the system from igniting the cartridges should
the transmitter switch be in the wrong position. I used an E-flite
10-amp speed control and removed the red power line on the servo
extension receiver, as the aircraft is powered from a different battery.
Charge up both a flight battery as well as a battery for the smoke
system. Turn your transmitter on and plug in the smoke battery. I
used a 3-cell 325mAh 11.1V Thunder Power LiPo pack. Use a multimeter to determine the on/off positions of your gear switch, as
well as the safety switch for the speed control. Don’t connect the
fuse just yet. Verify that there is no power at the two 2mm bolts at
Shown from left to right: the fully assembled smoke emitter, an electronic igniter, a
fuse, and a plastic cover to keep all contents contained.
The power and ground wire have each been soldered to a 2mm bolt. At the opposite
end of the bolt, one is to wrap the igniter wire around each bolt. This makes it
possible to quickly remove the igniter after a flight.
The smoke emitter is ready for installation. The green circular component is a fuse
wrapped within the inner diameter of the plastic cover, and this is where one also
secures the igniter. After the plastic cover is installed, I opted to secure it to the
emitter using clear tape.
Since this airplane features removable wings, one must connect the servo
extension and emitter wires when assembling the aircraft.
