Hola, te digo lo que pone en el manual del 61.
Abre la aguja lo suficiente para que el motor entre en modo 4 tiempos y rueda así 1 minuto, cierra la aguja de alta para que entre en modo 2 tiempos y haz intervalos de 2-tiempos a 4-tiempos 10 segundos cada uno hasta que se acabe el deposito.
El manual dice que con 1 deposito vale, pero yo le haría 2 o tres y luego seguir en el aire o hacerle uno en el suelo en ralentí alto y haciendo unas variaciones.
En cuanto a las mezclas yo le e echo a mi OS 120 10% de ricino desgomado de primera prensa y 10% de aceite sintético Klotz y un 5% de nitro.
Código: Seleccionar todoRUNNING-IN ("Breaking-in")
All internal-combustion engines benefit from extra
care when they are run for the first few timesknown
as running-in or breaking-in.
This allows the working parts to mate together under
load at operating temperature. Therefore, it is vitally
important to complete the break-in before allowing the
engine to run continuously at high speed and before
finalizing carburetor adjustments.
However, because O.S. engines are produced with
the aid of the finest modern precision machinery and
from the best and most suitable materials, only a
short and simple running-in procedure is called for
and can be carried out with the engine installed in the
model. The process is as follows.
Install the engine with the propeller intended for
your model. Open the needle-valve to the advised
starting setting and start the engine. If the engine
stops when the glow plug battery disconnected,
open the needle-valve to the point where the engine
does not stop.Run the engine for one minute
with the throttle fully open, but with the needlevalve
adjusted for rich, slow "four-cycle"operation.
Now close the needle-valve until the engine
speeds up to "two-cycle"operation and allow it to
run for about 10 seconds, then reopen the needlevalve
to bring the engine back to "fourcycle"
operation and run it for another 10 seconds.
Repeat this procedure until the fuel tank is empty.
Re-start and adjust the needle-valve so that the
engine just breaks into "two-cycle" from "fourcycle"
operation, then make three or four flights,
avoiding successive "nose-up" flights.
During subsequent flights, the needle-valve can be
gradually closed to give more power.
However, if the engine shows signs of running too
lean, the next flight should be set rich. After a total
of ten to fifteen flights, the engine should run
continuously, on its optimum needle-valve setting,
without loss of power as it warms up.
After the completion of the running-in adjust the
carburetor at optimum setting referring to
MIXTURE CONTROL VALVE ADJUSTMENT
section and SUBSEQUENT READJUSTMENT
section.
Un saludo
