INTRODUCTION

Congratulations and thank you for purchasing the Great
Planes Sport Scale PT-19 .46/EP ARF. The PT-19 is an easy
start to scale modeling, with easy sport fl ying characteristics
and the durability of an every-day fl yer.
For the latest technical updates or manual corrections, fi nd
the Sport Scale PT-19 ARF page on the Great Planes Model
Manufacturing web site at www.greatplanes.com. If there is
new technical information or changes to this model a "tech
notice" box will appear on the page.

ADDITIONAL ITEMS REQUIRED

Radio/Servos

A minimum 4-channels is required to fl y the Sport Scale
PT-19 ARF. The Tactic TTX660 is recommended because
of its simple, fl exible computer programming and multiple
model memory:
Tactic TTX660 6-channel programmable radio
(TACJ2660)
Tactic TR625 6-chanel receiver (TACL0625)
Hobbico 2S 6.6V 1300mAh LiFe battery (HCAM6411)*
On-off receiver switch (TACM2000)*
Servos nowadays are smaller and stronger, so we've designed
the servo mounts in the PT-19 to accommodate mini servos,
but full-size servos may still be used simply by enlarging the
openings in the servo mounts. Four or 5 channels are required
depending on whether you connect the aileron servos to
separate channels and mix them with programmable mixing
in your transmitter, or if you use a Y-harness to connect the
aileron servos to one channel.

If mixing the aileron servos electronically with programmable
mixing in the transmitter:
If connecting the servos with a Y-harness:
*If powering your PT-19 with a brushless electric motor the
BEC in the ESC may be used to power your receiver and
servos, so no receiver battery or on/off receiver switch will
be required.
The PT-19 is suited for a .45 - .55 cu. in. 2-stroke or .70 cu.
in 4-stroke. The O.S. Max .46AXII (OSMG0548) is illustrated
in this manual.
