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

 Century Sealing Iron (COVR2700)
