60.

 

Hold your elevator at neutral (on the same level as the horizontal stabilizer) and tighten the EZ Link connector onto the 
elevator pushrod. 

61.

 

If necessary, cut off the portion of the elevator 
pushrod that extends excessively behind the 
elevator servo‟s EZ Link connector.   
(NOTE: Leave approx. 

1/2

-inch of   

extra pushrod for possible adjustments). 

62.

 

If you use a glow engine, install your throttle 
servo and connect the throttle pushrod between 
your engine and throttle servo. 
(NOTE: For better appearance and 
airframe longevity, we recommend 
using an electric power system for 
this model. For scale-like flying 
using our U638109 motor, 100A 
ESC and a 19x6 propeller, you 
may use two 4S/4,000 mAh or 
above LiPo batteries in series. For 
extra power, we recommend using 
a 10S or 12S/3,900mAh or above 
LiPo battery – or three 4S LiPo 
batteries in series, with an 18x8 to 
20x8 propeller.) 

63.

 

If you use an electric motor,   
confirm or correct its direction   
of rotation. 
(NOTE: If you are using an electric 
power system, inserting some foam   
rubber (not included) inside the engine 
mounting box may serve as a „safety 
cushion‟ for your flight battery.   
The PT-17‟s spacious cockpit permits 
great flexibility in where you install your 
radio and power system components.   
During all of our EP flight tests the ESC 
was mounted behind and below the 
engine mounting box and we secured   
our radio‟s battery above and to the left 
of the ESC as pictured at the right. Our 
receiver was held in position with 
double-sided foam tape at the right-hand 
side of the servo tray as shown below. 
 
 
 
 
 
 
 
 
 
 
 
 
 
Wait until you are ready to adjust your PT-17‟s center of gravity to decide on the final positions of your batteries. 
 

IMPORTANT: 

To avoid 

sparks, 

always 

c

onnect the 

ESC to your 

flight battery 

first,   

THEN 

connect the 

anti-spark 
connector.
