intake and the bottom of the cowl. If there is less than 1 1/2", make an
opening in the cowl below the carb at least as large as the carb intake
diameter.
7. A long, narrow, screw driver is recommend to drill small holes in the cowl for
adjusting the needle valves, since the carburetor must often be adjusted
differently with the cowl on as compared to off.
8. These engines burn between one and two ounces of fuel per minute.
Therefore, a 32 ounce or larger tank is recommended. The engines are
equipped with a diaphragm pump carburetor making tank location not
critical relative to the carburetors fuel entry position. Place the tank on the
aircraft's center of gravity (CG). Then aircraft trim changes during flight will
not be necessary from a full to an empty tank
FUEL:
Clean petrol 93# is strongly recommend for your DLA engines. Lubrication
Ratio of trial Run is 30：1 while normal flying is 40：1, Higher-octane fuel will
not generate more power and may cause the engine to run slower and
overheat.
Note:
Damage caused by fuel additives, such as nitro, over-lean carb
settings, over-advanced timing, and over-heating are not covered under
warranty.
Ignition system
It is important to understand how the ignition system is to be wired. Mount the
ignition module using the four supplied rubber grommets so as to create a
1/16" gap between the ignition module and the mounting surface. Without this
1/16" gap the ignition module can overheat.
Important: If the electronic ignition overheats it will malfunction (e.g.,
backfiring or shutting down).
Ignition details:
• The red cable is positive (+),while the black is negative(-).
• Working voltage: 4.8v-6v
• It is important to achieve the correct coordination of the sensor(s) to the
magnets for fitting a new ignition.
The propeller selection and installation
Make sure the prop, spinner and prop bolts before each flight! Loose prop
bolts allow prop movement which will shear the bolts.
Selection： ： ： ：
• The following props are recommended: 22cm*8cm, 22cm*10cm
• Only use propeller sizes that are recommed above for your engine
