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. 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 25:1~30:1, while
normal flying is 40:1~50:1,
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
DLA Ignition details:
• The red cable is positive (+),while the black is negative(-).
• Working voltage: 6.6V~8.4V
(7.4V
，
2S Li-Po battery is recommened)
• Please connect battery to DLA ignition directly.
• 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: 22*10, 23*10, 23*8
，
24*8
• Only use propeller sizes that are recommed above for your engine
• The propeller blades must be of the same length.
Installation
：
• You must use a drill press to drill your propeller from the rear.
• A drill guide is recommended, but the propeller washer can be used as a drill
template. (Fix the propeller washer onto the propeller in the center-bore using
a bolt and nut.)
• Keep your propeller balanced.
• Screw thread-locking glue is necessary
