Step 41

Du-Bro  steel  landing  gear  straps  are 

used to retain the landing gear leg.

Step 42

When  opening  up  the  cowl,  give  the 

motor  plenty  of  space  for  cooling  air. 

This  is  a  fi berglass  cowl  fabricated 

for  the  prototype  model.  Install  the 

mounting  screws  so  they  screw  into 

the 1/4” ply fi rewall and then harden the 

holes with CA.

Step 43

Installation of the servo’s. Note that the 

center  push  rods  utilize  a  Z-bend  to 

maintain a low profi le to allow space for 

the aileron servo. Make sure all linkages 

are snug with no play. Note that a small 

amount  of  material  was  removed  from 

the fuselage doubler to allow clearance 

for the throttle linkage connector block. 

Temporarily install all linkages, the motor 

and the fuel system before covering. You 

may have to remove a small amount of 

material at the corner of the fi rewall for 

muffl er  clearance  depending  on  your 

choice of motor.
