pre-flight & testing

Motor:

 Should run smoothly at all stick positions, and transition 

smoothly  from  low  to  high  RPM.  If  the  motor  is  turning 
backwards, reverse two of the three wires between the motor 
and  ESC.  Check  that  the  screws  holding  the  motor  to  the 
airframe are tight and secure.

Flight Controls:

  Set all to neutral or level positions with sticks 

in the neutral positions. Ensure that all controls and linkages 
move freely. Double check that all hinged areas are free from 
rips or tears. Verify proper control surface directions. Right Roll 
is – right aileron up, left aileron down, Left Roll is left aileron up 
and right aileron down.

Batteries:

  Should be fully charged prior to each flight.  Watch 

transmitter  battery  level  and  follow  manufactures 
recommendations.  Motor  battery  should  not  be  drained  any 
further than recommended by the manufacture, use a timer to 
prevent an over discharged condition.

Radio:

 All trims should be set to neutral and throttle in the low 

position. Check that rate switches and mixes are set properly.

Range Check:

 With and without the motor running per radio 

manufactures  instructions.    If  there  is  insufficient  range  or 
significant reduction with the motor running, resolve and re-test 
before flying.

The  first  flights  should  be  done  with  the  CG  at  the 
recommended  position,  and  reduced  control  rates  until 
comfortable  with  your  handling  of  the  aircraft.  As  your 
experience with the aircraft grows experiment with different CG 
points and control rates. After all flights, check the aircraft over 
for damage and/or other items that may adversely affect flight 
performance.

This   Extreme 3D Plane is a full performance aircraft and will 
provide hours of entertainment, including the occasional crash.  
If,  as  the  result  of  a  crash,  the  foam  tears,  simply  glue  with 
Welders or CA.  Many pilots prefer Welders because it remains 
flexible after drying. CA however, is more suited for the “quick” 
repair.

This aircraft can be flown indoors or outdoors. It is however 
designed specifically indoor flying and will be right at home in 
the local gymnasium or other similar sized venue.

Storage

This EPP plane should be stored resting it's landing gear or 
hung from the prop. Storing in other fashions that put stress on 
the airframe could cause the airframe to distort. Storage in a 
hot car could also cause damage.
