INTRODUCTION
Thank you for purchasing the Tower Hobbies Cherokee EP.
This Cherokee is intended for electric power only, so the
structure has been lightened accordingly to make it a nice
little scale fl yer. Tricycle landing gear is the icing on the cake
for easy ground handling, takeoffs, and landings.
NOTE:
This instruction manual illustrates all the steps
necessary to assemble the ARF (almost ready-to-fl y) edition
of the Cherokee EP. However, the Rx-R (receiver-ready)
edition requires less assembly, so if assembling the Rx-R,
simply skim through the manual and perform only steps
that apply.
For the latest technical updates or manual revisions, fi nd the
Tower Hobbies Cherokee EP page on the Tower Hobbies
website. 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 4-channel radio is required to fl y the Cherokee. The Tactic
TTX660 is recommended because of its simple, fl exible
computer programming and multiple model memory. The
servo mounts in the Cherokee are sized for Tactic TSX10 micro
servos, but the mounts may be enlarged for other servos.
❍
Tactic TTX660 6-channel programmable radio
(TACJ2660)
❍
Tactic TR625 6-channel receiver (TACL0625)
❍
(4) Tactic TSX10 micro digital, high-torque, metal gear,
ball bearing servos (TACM0210)
Brushless Electric Motor
The Cherokee fl ies on a RimFire .10 with a 3S 2200mAh –
3200mAh LiPo and a 9 x 6E propeller (APCQ4118) and 40A
ESC (GPMM2140):
❍
Great Planes RimFire .10 35-30-1250 Outrunner
Brushless (GPMG4595)
❍
LiPo 30C 3S 11.1V 2200 Star (ONXP2263)
❍
LiPo 30C 3S 11.1V 3200 Star (ONXP1953)
❍
Programmable ESC 40A BL 2S-6S (GPMM2140)
❍
APC 9x6E Thin Electric Propeller (APCQ4118)
LiPo Battery Charger
To charge a 3S 3200mAh LiPo at 1C a charger capable of
at least 40 watts is required (3S x 4.2V/cell = 12.6V x 3.2A =
40 watts). The Triton EQ (GPMM3155) is more than enough
charger with 50W output using AC and 63W output using DC.
Adhesives, Hardware & Other Accessories
Other than common hobby tools, here is a list of items
required:
❍
30-Minute epoxy (GPMR6043)
❍
Epoxy brushes (GPMR8060)
❍
Mixing cups (GPMR8056)
❍
Mixing sticks (GPMR8055)
❍
Threadlocker thread locking cement (GPMR6060)
❍
Thin CA (GPMR6001)
❍
Medium CA (GPMR6007)
❍
CA applicator tips (HCAR3780)
❍
CA accelerator (GPMR6035)
A covering iron with a cover sock will probably be required
for tightening and re-bonding to the model any covering
that may have loosened between the time the covering was
applied and the time the model was removed from the box.
The 21
st
Century iron is preferred because of its long cord,
contoured shoe, and precisely adjustable temperature range:
❍
Coverite 21
st
Century Sealing Iron (COVR2700)
❍
