Range check radio.

  Follow the radio makers 

guidelines  for  performing  a  proper  range 

check.

Check  for traffic. 

 Proceed  to the flight line 

(With  your  mentor/instructor  if  you  are  a 

novice pilot) and observe other RC traffic.    If 

the  runway  is  clear,  and  no  one  is  in  the 

pattern  to  land,  loudly  announce  your 

intentions  to  take  off.    Remember  etiquette 

dictates  that  all aircraft on  ground  must yield 

the runway to those landing.

Go flying.

   Point model into wind (if present) 

and  steadily  advance  throttle  to  full.    Use 

rudder  to  correct  track  while  on  ground  roll.  

Within  several  feet  the  model  should  be 

airborne.    Fly  model  to  a  comfortable  1-2 

mistake  high  altitude,  reduce  throttle  to  stop 

climb,  then  trim  model  for  straight  and  level 

flight  at  a  comfortable  cruise  speed 

(Depending on speed control responsiveness, 

the 

1946  “Say’s  Nuh!”  C-140

  typically 

cruises at just over 1/2 throttle).

Setup  for  landing. 

  Clearly  announce your 

intention  to  land.    Make  landings  into  the 

wind.    With  rudder/elevator  control  and  no 

ailerons  setting  up  landings  in  cross-winds 

should  be avoided  until  you  are  comfortable 

with the model’s in-flight behavior.

Congratulations!

You’ve  completed  your  first  flight(s)  on  your 

Stevens Aero  

1946 “Say’s Nuh!” C-140

.

By  now  you’ll  have  noticed  that  the

  C-140

  is  a 

very  stable  airplane.    When  built  straight,  and 

trimmed for  level flight,  it  should readily return  to 

wings  level  from any  attitude.    We’ve found  the 

C-140 

to  capture  the  imagination  of  prospective 

pilots  both  young  and  old.    We  never  miss  an 

opportunity to allow an on-looker at the field to get 

some stick time in with the 

C-140

.  

If  your  first  flight  was  a  bit  more  exciting  than 

you’d  have  liked  and  are  having  problems  with 

erratic   flight  performance;  please  inspect  your 

equipment  and  airframe  for  damage,  improper 

installation,  and/or  twists  and  warps.    The  most 

common mistake is  to try and fly with a warped or 

twisted  wing.  Make  certain  that  your  wing  is 

straight before you fly.

We  are  committed  to  improving  your  build  and 

flying experience  and  are  constantly  refining our 

processes,  designs,  and  manuals  to  reflect 

customer  feedback.    You  may  correspond  with
