User manual

Fuel
Must need to use high octane gasoline, alcohol based glow fuel cannot be used in TP70 engine.
TP70 engine use 40:1 ratio mix gas fuel , must use fully synthetic two stroke oil .Follow the oil
manufacturer's recommendations concerning the mixture ratio of gasoline and oil .
A 400cc tank will provide 10-15minutes normal flight, use a tank designed for gasoline.
Prop
Make sure that the propeller is well balanced. The choice of prop depends on the design and
weight of the aircraft and on the type of flying in which you will be engaged. Determine the best
size and type after practical experimentation.
Suggested Props: 24*823*12, 24*10
TH
(Mejzlik),24*12(Mejzlik).
Make a habit of always checking the tightness of the prop before starting the engine.
tp70 on the ground test, 5400-6400rpm appropriate speed. Excessive load and high speed will
cause engine damage.
Running-in/Starting
WARNING:
When ground running the engine, avoid dusty or sandy locations. If dust or grit is drawn into the
engine, this can have a ruinous effect, drastically shortening engine life in a matter of minutes.
Initial needle positionWhen starting the engine for the first time, set the high speed needle 1.75
turns open and the slow speed needle 1.5 turns open from the fully closed position.With this
position both high and slow speed mixtures will be rich. If the settings are upset, come back to this
setting and adjust them according to procedure in the needle setting section.
Use a fuel with increased oil content and set the needle a little on the rich side. Too rich a needle
setting may cause misfiring or erratic running due to fouling of the plug.
Use a 40:1 fuel/oil mixture if the particular brand of oil states50:1 mix. Set only the high speed
needle 200RPM below maximum rpm. The low speed needle need not be richened.
No need to carry out running-in on a bench nor with the model fixed. Just fly the model with the
above mentioned fuel and needle setting. A total of 10 flights(3~4 litters fuel) are required.Avoid
prolonged full throttle running at initial stage, and gradually extend the full throttle running time.
It is suggested to use an electric starter for safety
Starting with a chicken stick or gloved hand
1Close the choke valveturn on the ignition switch
2Pull down the throttle to 1/8 opened position
3Flip the propeller until the fuel reach the carburetor and you hear explpsion several times
4open the choke valve
5flip the propeller with a chicken stick to start the engine

Consumption current is 400mA/6000rpm/6V.User a power source of more than 1000mah capacity
Install the ignition module taking sufficient anti vibration measures
The voltage of power source is 4.8-6V
