Trimming Servo Arms

 

24)

 

Installing Radio Gear: 

Gather the following items: 
-Two Sub-micro Servos (i.e. Blue-Bird 
BMS-306BB) 
-Fully Charged 4.8V Receiver Battery 
(i.e. Dream-Flight 4.8V 300mAh NiMH 
pack) 
-Sub-micro Receiver of choice 

    

-Transmitter (battery fully charged) 

 
25)

 

If your servos do not include a single-arm 
control arm, simply trim off one 
extraneous arm from each control arm, 
using flush-cutting pliers. See Figure 7. 
CAUTION: Wear protective eyewear 

while trimming, as excess arms tend to 
pop off with great velocity. 

 

26)

 

In order for lightweight pushrod links to 
connect to servos, you need the servo 
arm hole to be 1.6 mm (1/16 in). If 
necessary, enlarge hole that is 10-12 
mm from center screw hole using a 1.6 
mm (1/16 in) drill bit.   

 

27)

 

Programming Transmitter/Controller:

 

Turn on transmitter. Enable “Elevon” or 
“V-tail” mixing and set all trims to zero. 
Set transmitter’s independent elevator 
throws to 20% and aileron throws to 
60%. This is simply a good starting 
point. Please note that very little 
elevator travel (i.e. up and down 
movement of the control surface) is 
required for pitch control. Too much pitch 
control will make the glider difficult to 
fly. Good rule of thumb: set elevator 
(pitch) rate to 1/3 of the total aileron 
(roll) rate (i.e. deflection). 

 

28)

 

With transmitter still on, temporarily plug 
servos into elevator and aileron ports of 
receiver. Now, plug battery directly into 
receiver. The servos will center upon 
start-up. Before proceeding, check trim 
adjustments on transmitter to make sure 
manual trims, as well as sub-trims, are set to zero. This will ensure that servos are absolutely centered. 
Lay R/C components loosely on underside of fuselage. See Figure 8.
