RCV58-CD FOUR STROKE ENGINE OWNERS GUIDE
Thank-you for choosing an RCV Engine. With simple care this design can offer you years of trouble free service.
Some aspects of the RCV engine
are different to conventional engines therefore even if you are an experienced modeller please read all these instructions carefully before
using your engine. Please pay particular attention to the RCV CD do’s and don’ts listed below before attempting to run your engine.
READ ALL INSTRUCTIONS BEFORE OPERATING YOUR RCV ENGINE!
WARNING! :-
Under no circumstances should the crankcase breather nipple be extended. If extended the oil resi-
due can cause crankcase compression which will restrict oil lubrication to the bottom end.
RC model airplanes & engines are not toys and are capable of causing serious injury to yourself and others if improperly used. You should
always:-
•
Keep hands and all foreign objects clear of the engine when it is operating.
•
Mount the engine securely on a bench mount or plane.
•
Use a good quality balanced propeller with no cracks or flaws, ensure this is tightened prior to each use.
•
Run your engine in an well ventilated area.
•
Not hand start the engine.
•
While the engine is running stand behind the engine to make adjustments and ensure proper safety clothing is always used (eye goggles and
gloves).
The safe operation of your engine is your responsibility so ensure that you operate your engine with care at all times and ensure all
spectators are kept at a safe distance.
SECTION 1
RCV 58CD DO's & DON'Ts
READ ALL THE INSTRUCTIONS BEFORE OPERATING YOUR
ENGINE
If in doubt, contact RCV Engines for advice.
ONLY USE RECOMMENDED FUELS
We recommend you use a methanol based fuel containing 10% Nitro.
We recommend Westonuk Liquid Gold Prosynth 2000 10% nitro fuel.
For more information on fuels please see
SECTION 3
.
ONLY USE RECOMMENDED PLUGS
For reliable running we strongly recommend the use of an PP4T plug.
Fitting a non-recommended plug may produce a significant drop in per-
formance when the glow battery is disconnected.
ALLOW FOR PROP-
SHAFT CENTRE-LINE OFFSET
The propshaft centre line is offset 3 mm above the engine bearers.
When installing the engine in a model ensure this is taken into account.
SET UP THE CARBURETTOR CORRECTLY
As supplied, the idle needle is set at rich to protect the valve. To achieve
smooth running after running in, this must be adjusted as per instructions.
(SEE SECTION 6)
ENSURE THE EXHAUST IS PROPERLY TIGHTENED
Prior to use, tighten the exhaust pipe and muffler using the recommended
procedure
(SEE SECTION 4)
ENSURE ADEQUATE COOLING
4-stroke engines tend to run hotter than 2-strokes so provision for cooling
is important (
SEE SECTION 7
)

despatch. Your engine will be covered in a light coating of oil
used to protect it during transit.
2.

3.
A photo user manual is also available for download from the RCV
website - www.rcvengines.com
GLOW PLUG
•
As the glow plug on the RCV is ported, selection is more critical
than on conventional engines, and fitting a non-recommended plug
may produce a significant drop in performance when the glow bat-
tery is disconnected
. It is strongly recommended that the Pro
plug PP4T is fitted which has been specifically designed for
the RCV range.
•
DO NOT USE AN IDLE BAR PLUG. This may protrude into the
rotary valve, and lock the engine up, damaging the surface of the
rotary valve.
FUEL
•
For maximum efficiency, we recommend that 10% Nitro content
fuel is used. Fuel with too low a Nitro content will produce a
significant drop in RPM when the glow battery is disconnected as
well as a less reliable idle. Do not use fuel with more than 15% Nitro
as this could result in engine damage.
•
Recommended Westonuk Liquid Gold Prosynth 2000 10% nitro
fuel.
•
Cheap fuels or home blended fuels may reduce the lifespan of the
engine. If
•
If Prosynth 2000 fuel is not available we recommend a fuel with a
high quality oil content with no castor.
PROPELLERS
•
The RCV58-CD engine uses conventional sized propellers.
There are numerous different sizes of propellers which could
be used and this is really dependent on the airframe and the type
of flying.
•
For general running in etc, RCV recommend an 11 x 6 or 12 x 6
APC type prop. These propellers give a good all round
performance. Examples of suitable propellers are listed below.
•
We would recommend you try a number of different propeller sizes
and see which suits yourself and the application best.
•
Once your engine has been fully run in, you should expect the
following performance (this is a guideline only):
