AT A GLANCE ...
Powering the Addiction XL is a pair of inexpensive 3S 2,200 mAh LiPo
batteries. Many of us have these packs from other projects, so it’s a less
expensive alternative to a dedicated a 6S pack.
The Addiction XL is
designed around a
Thrust 50 motor and
a matching Quantum
70 Pro ESC. They fit
perfectly and have
plenty of power for
Kevlar cables, which won’t stretch over time. After they
have been run through the fuselage, each cable is adjusted to
length and the included hardware makes for a quick and easy
The power comes from a Precision Aerobatics Thrust 50
brushless motor. The Addiction XL is designed around this
motor and using a different one would likely require some
modifications. It quickly bolts in position because the holes are
predrilled in the
the motor is
Quantum 70 Pro
ESC with BEC.
It’s held in place
on the side of the
motor box. After it
is connected to the
motor and the Deans connectors are soldered in place for the battery connections,
the cowl is fitted. You might have to do some filing to create clearance for the main
gear struts. Locate and drill the positions for the four mounting screws and bolt the
cowl in position.
To finish the Addiction, attach the VOX propeller and carbon-fiber spinner, and
then install the receiver. Although you can use a four-channel system, I chose to
separate the left and right ailerons into their own channels, mixing them in the
transmitter and using five channels. This offers independent trims for each aileron, as
well as the option to later program in spoilerons.
An optional Vortex Generator kit was also included with the review Addiction
XL. These specially cut carbon-fiber pieces attach to the wing, and fit in precut
holes. Simply slit the covering in these spots and epoxy the pieces into place on the
upper and lower side of each wing half.
The completed, ready-to-fly Addiction XL came in at 4. 75 pounds with the two
3S 2,200 mAh batteries connected in series in place. It’s slightly heavier than the 4. 5
pounds stated in the manual, but it balanced in the middle of the CG range.
I programmed my radio using the recommended throws,
rates, and exponential as suggested in the manual. Precision
Aerobatics recommends three flight modes: low rates, high
rates, and extreme rates.
