Fuselage Continued

56.

Connect the ‘snake bend’ of the push rod to the center hole of the elevator  servo, which is 

the servo farthest from the antenna.

57.

Mount the receiver by engaging the rear edge of the circuit board with the notch in the short 

arm of  the  receiver  clip.    Gently  press  down  on the front edge of the  circuit  board  while 

gently pulling back  on the long arm of the receiver clip, until the circuit board snaps into the 

notch in the long arm of the clip.

58.

You may now cover the bottom of the fuselage.   Leave the area over  the receiver open to 

provided access for the battery.

59.

Motor Installation - Paint balsa part M1 (located in your  hardware bag) flat black.   Align M1 

over the etched guide lines on the front of F19, and against the bottom of the motor  mount 

plate.  Secure by wicking thin CA between M1 and F19.

60.

Paint the dummy radial engine flat black.   

Tip! paint all of the ply parts while they are still in 

the sheet of ply, as they are easier to handle this way.

  Test fit the dummy engine to the tabs 

on the  front  of the motor  mount plate.   

Do  not  bond!

    If M1 interferes  with  the fit of  the 

dummy engine, carefully sand away the face of M1 until a good fit is  achieved.  Remove the 

dummy engine and set aside.

61.

Trim the spikes from the mounting tabs of the motor [PKZ3624] and sand the tabs smooth.

62.

Feed the motor [PKZ3624] lead through the openings  in F19, the landing gear pocket, and 

F8, then into the radio compartment.

63.

Slide the motor  through the slot in F19 and onto the motor  mount plate.   Ensure that  the 

motor rest flat on the plate, and all the way back in the cut-out in the plate.  This  will ensure 

that  the  motor  has  the  correct  down  and  right  off-set  for  proper  flying  characteristics.  

Ensure that the tabs  at the front of the mounting plate extend beyond the motor  -  to allow 

proper  fit  of  the  dummy  engine  -  then secure  the motor  by  wicking  thin  CA  under  each 

mounting tab.
