INTRODUCTION

 

Congratulations on your purchase of the EDGEtra ARF. We hope you 
will enjoy this R/C sport aerobatic/3D model. 

Assembly  of  your  EDGEtra  is  fast  and  simple  when  following  the 
detailed instructions in this manual.  We urge you to read this assembly 
manual  completely  before  assembly.    Familiarize  yourself  with  the 
parts and the assembly sequences.  The successful assembly and flying 
of  this  airplane  is  your  responsibility.  If  you  deviate  from  these 
instructions, you may wind-up with problems later on.   

Good luck with the EDGEtra. Let’s get started! 

ADDITIONAL ITEMS YOU WILL NEED TO PURCHASE

 

In addition to this kit, you will need the following items to complete 
your EDGEtra and make it flyable. 

❑

  RADIO SYSTEM

 

      The EDGEtra requires a standard 4-Channel  radio  system  and  four 
      ‘Mini’ sized High  Torque servos.   High  Torque  Mini servos  typically 
      have 70+ oz. of torque.  In addition, you'll need two 6” long Servo 
      Extension Cords and one Y-Harness Chord for connection of the two 
      aileron servos to the  receiver.  (The  length  of  extension  wire  you 
      will need depends on how long the wires are coming off your servos. 
      With  Hitec®  High  Torque  mini  servos  we  used 6”  long  extension 
      wires.  Check your servos and plan accordingly.) You will also need 
      one 18” servo extension wire to connect the elevator servo to your 
      receiver.  In addition, you will need three (3) 1-1/2”  servo  arms  for 
      the elevator and aileron servos, and one (1)  3” dual  arm  servo  for 
      the pull-pull rudder servo. 
     

 

POWER RECOMMENDATIONS 
 

❑

  600-1200 watt BRUSHLESS OUTRUNNER MOTOR

 

      There are many fine 600 to 1200 watt electric outrunner motors on 
      the market that will fly the EDGEtra.   We use  the  Himax  HC4220- 
      770 (SIG Part# 

MXACC4220770)

 Brushless Outrunner Motor.   

 

Specs:  
Case diameter: 42mm                

 

Case length: 50mm                  
Shaft diameter: 5.0mm                

                                           

  

Weight: 200g (7 oz.) 
Max Watts: 800 

                  KV = 770 

Rm = .02     Lo = 2.0 

❑

  60-80 amp ESC (Electronic Speed Control)

 

      We use the Castle Creations  Phoenix  EDGE  75  ESC  or  the  Castle 
      Creations Phoenix EDGE Lite 75 ESC (SIG Part# CSE010011200).  We 
      typically see an amp draw of 30 to  60  amps,  depending   on   prop 
      size.  

       NOTE: The Castle Creations  ESCs  that  we  used, as  well  as   many 
       of the other ESC s on  the  market,  have  a  BEC  (Battery  Eliminator 
       Circuit) built in.  BEC allows you  to  use  the  same  battery  pack  to 
       Power  both  your  motor  and  your radio  system,  eliminating  the 
       normal radio battery pack.  As the dual purpose battery runs  down 
       in flight, the BEC  circuit in  the ESC  will shut  down the  motor  and 
       leave enough power to operate the radio while you land the model. 
      Check the manual of your particular ESC to learn how to use the ESC. 
 
 

           SIG EDGEtra Electric Combo (SIG Part# SIGRC107EPARFC) 

                 Himax 4220-770 motor   
                 (SIG Part# 

MXACC4220770

)

 

Castle Creations Phoenix Edge Lite 75 Amp ESC 

                (SIG Part# CSE010011200) 
          
          We recommend purchasing the above combo for the EDGEtra –  
          This package is available directly from SIG Manufacturing. 

 
 
 

❑

  4 Cell 4000-5000mah LITHIUM-POLYMER BATTERY PACK

 

     With the  Himax  HC4220-770 motor  we  use  a 4 cell (4S1P)  4000 – 
     5000mah   LiPo   pack. We  found  that  4000mAh LiPo packs provide 
     between 6 and 8  minutes  of  flight  time,  depending   on   propeller 
     selection  and  other  factors  (quality of pack, throttle management,  
     outside  temperature,  etc.). 
 
      
 
 

❑

  PROPELLER

 

      With the Himax  4220-770  motor   and   a  4-cell  (4S1P)   14.8v   LiPo 
      pack,  we recommend a 15 X 8E Wooden Propeller. 
  
      Your propeller  may vary due  to  other  factors  – the specs   of   your 
      individual   motor   and    battery    pack,  etc.   You   may    need    to 
      experiment  with  different   props to  find  your  best  combination. 
 
 
 

               

 

❑

  BATTERY CHARGER

 

      FOR SAFETY AS WELL AS PERFORMANCE,  CHARGE  LIPO  BATTERIES 
      ONLY WITH A LIPO BATTERY CHARGER!   
      In addition to providing the critical charging profile needed to safely 
      charge  LiPo  batteries,  a  LiPo   battery  charger  also   includes   the 
      capability of "balancing" the available voltage in the  cells,  ensuring 
      that the battery pack is at peak  capacity at  the  end  of  the  charge 
      cycle.  This translates to better flight times  and  a  longer  life  from 
      the battery pack. 
 
 

 

❑

  ARMING SWITCH (Optional) 

      While not a requirement to get your EDGEtra in  the  air,  an  arming 
      switch will help your  aircraft  be  safer.   SIG  Mfg.  offers  the  Maxx 
      Arming    Switch    (SIG   Part#   MXACC6972).      This   switch    is    a 
      Physical   cut  off  between your flight battery and the ESC. With the   
      removable  plug disconnected, there  is  no   way   the   motor   can 
      inadvertently  start.
