ASSEMBLY PHOTO-INSTRUCTIONS 

1.

 

Using the mounting hardware supplied with your 
motor or a mount recommended for your engine 
(not supplied), test-fit your motor or glow engine 
to the forward-facing surface of the engine 
mounting box („firewall‟). Center the propeller 
shaft on the intersecting lines on the firewall   
that form an „X.‟ Mark the firewall where 
openings are needed for mounting your motor or 
engine. If you are using a glow engine, point the engine‟s cylinder head toward the 
ground. (Use the “L” and “R” on the sides of the engine mounting box as viewed 
from the pilot‟s seat to determine which way is “down.”) 

2.

 

If you are using a glow engine: Decide where to 
install your throttle servo and mark where to 
make an opening for the throttle pushrod and 
fuel line (not supplied). 

3.

 

Form all necessary openings in the firewall. 
Mount your engine or motor onto the firewall 
(use threadlock compound to help protect the 
motor or engine mounts from vibration). 

4.

 

Insert the engine mounting box into the fuselage with the side marked “L” toward 
the pilot‟s left-hand side to maintain the right and down thrust built into the engine 
mounting box‟s firewall. 

5.

 

If you use an electric motor: Test-fit the dummy engine over your motor and to the 
PT-17‟s nose.    If you use a glow engine: As pictured below, remove one dummy- 
engine cylinder and its adjoining crankcase to test-fit the dummy engine over your 
glow engine; also remove material from a neighboring cylinder to make room for 
your engine‟s exhaust pipe and muffler if necessary. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

NOTE: The 

unpainted dummy 

engine pictured in 

several places in 

this manual is a 

prototype; details 

of construction 

may vary. All 

dummy engines 

produced for this 

ARF will be 

prepainted when 

shipped.
