3. Move the elevator up with your transmitter and move 

the ruler forward so it will remain contacting the trailing edge. 
The distance the elevator moves up from the center is the 
“up” elevator throw. Measure the down elevator throw the 
same way. 

❏ 

4. Measure and set the high and low rate elevator throws 

and the high, low and 3D rate throws for the rest of the 
control surfaces the same way. 

Note: We put exponential into the High rates and the 3D rates 
to make the control throws less sensitive around neutral. 
These can be set up to your own preference and flying style. 
We put 20% to 30% in the high rate and 50% to 60% in the 
3D rates. 

Finish the Model

❏ 

1. Use a prop reamer or drill bit to enlarge the 

spinner 

back plate

 to fit your motor’s prop adapter. Install the 

spinner back plate, propeller with washer and prop nut and 
the 

spinner cone

. Secure the spinner cone to the back plate 

with two 

3 x 12mm sheet metal screws

.

❏ 

2. Apply the 

instrument decal

 to the front of the 

cabin floor

.

❏ 

3. To install the cabin floor in the 

canopy hatch

, slide the 

cabin floor into the cabin hatch from the front. If you prefer to 
install an optional pilot figure, it will need to be installed as 
the cabin floor is slid in. Once the floor is in, a pilot figure will 
be difficult to install. Use thin CA to glue the cabin floor to the 
canopy hatch frame.

❏ 

4. To install the canopy hatch on the fuselage, insert the 

two guide pins in the front of the hatch in the two holes in the 
front of the fuselage. Push the hatch down and slide it back. 
The plywood tab on the bottom of the hatch should slide 
under the frame in the fuselage and lock the hatch in place.
