Items necessary for starting

Tools,  accessories,  etc.The  following  items  are 
necessary for operating the engine.

Battery leads

Glowplug battery

The power source for heating the glowplug may be 
either a large heavy-duty 1.5volt dry cell, Ni-cd battery 
or glowplug Igniter.

1.5 volt dry cell

These are used to conduct current 
from  the  battery  to  the  glowplug. 
Basically, two leads, with clips,  are 
required,  but,  for  greater  conve-
nience,  twin  leads  with  special 
glowplug connectors, as shown on 
the right, are commercially available.

Battery leads

glowplug Igniter

Make  sure  glowplug  element 
glows  bright  red  inside  room 
or shadow.

Battery leads

In case of 1.5volt dry cell

12V Battery

Starter

Electric starter and starter
battery                                 

An  electric  starter  is  recom-
mended for starting.

Hexagon starting shaft

This  shaft  mounted  on  an 
electric starting motor is driven 
into  the  shaft  cup  to  turn  the 
engine.

BEFORE STARTING

13

Select, by practical tests, the most suitable fuel from among 
the best quality fuels available in your country for helicopter 
use. For the best throttle response, a fuel containing 10% to 
30%  nitromethane  is  preferable.  Lubricants  may  be  either 
castor-oil  or  a  suitable  synthetic  oil  (or  a  blend  of  both) 
provided that they are always of top quality. For consistent 
performance and long engine life, it is essential to use fuel 
containing  AT  LEAST  18%  lubricant  by 
volume.  Some  fuels  containing  coloring 
additives  tend  to  deterriorate  and  may 
adversely  affect  running  qualities.  If  in 
doubt compare to a fuel known to be good.

Model engine fuel is poisonous. Do not allow 
it  to  come  into  contact  with  the  eyes  or 
mouth. Always store it in a clearly marked 
container and out of the reach of children.

Reminder! 

Fuel

Model engine fuel is also highly flammable. 
Keep it away from open flame, excessive 
heat, sources of sparks, or anything else 
which might ignite it. Do not smoke, or allow 
anyone else to smoke, near to it.

Alternatively, one of the purpose-made 
manual or electric fuel pumps may be 
used to transfer fuel directly from your 
fuel container to the fuel tank.

Manual

Electric

Install  a  filter  to  the  outlet  tube  of  your 
refueling  container  to  prevent  entry  of 
foreign matter into fuel tank. O.S. ‘Super 
Filters’ (large and small) are available as 
optional extras.

O.S. Super Filter (Fuel Can Filter)

It is recommended to install a good in-
line  filter  between  the  fuel  tank  and 
carburetor  to  prevent  entry  of  foreign 
matter from getting into the carburetor.

Fuel Filter

Heatproof  silicone  tubing  of  approx. 
5mm o.d. and 2.5mm i.d. is required 
for  the  connection  between  the  fuel 
tank and engine.

Fuel Pump

Silicone Fuel Line
