Magnum XL .30RFS Operating Instructions Manual - page 5
QUICK START and TROUBLESHOOTING GUIDE
The following information is provided to get your new Magnum XL .30RFS running right away with minimal effort. We have listed our
recommendations for fuel, propeller, starting procedures and other recommended accessories. Also included is general information
about the accessories needed for the Magnum XL .30RFS engine that we hope you will find helpful.
This Quick Start Guide should not be used as a replacement to the Operating Instructions included, rather it should be used along with the
Operating Instructions. We highly recommend reading through the Operating Instructions to familiarize yourself with each part of the
engine, along with the proper procedures for engine break-in, tuning, care and maintenance.
OUR RECOMMENDATIONS
The following items are recommended for use with the XL .30RFS
engine. These items are recommended for initial start-up and running.
Please read through the Operating Instructions for further details.
q Fuel: Power Master 10% 2-Stroke Blend (# 275180) for break-in.
Power Master 10% 4-Stroke Blend (# 275185) for normal use.
We suggest using Power Master brand fuels. Power Master fuel comes
in 10 % and 15% nitromethane contents that can be used in the XL .30RFS
engine. Power Master fuels are blended using only high quality
nitromethane, methanol, Castor Oil and synthetic lubricants to provide
high power output along with easy starting and unmatched lubricating
and heat dissipation qualities. For the extra lubrication necessary for
break-in, use 10% 2-stroke blend. After break-in, for extra performance,
use 10% - 15% 4-stroke blend.
q Fuel Tank: Hayes 8oz. Fuel Tank (# 070)
The Hayes 8oz. fuel tank is a perfect match for the XL .30RFS. It is
large enough to give you about 15 - 20 minutes of run-time at full throttle,
and is possibly the easiest fuel tank to assemble and maintain.
q Glow Plug: Thunderbolt 4-cycle (# 115490)
The Thunderbolt 4-cycle glow plug is designed to be used in four stroke
engines using fuels containing 10% - 20% nitro content and in any envi-
ronment. It is a “hot” type of glow plug for easy starting, excellent transi-
tion and incredible top end. The plug is also very durable and able to
withstand repeated use, day after day.
q Propeller: APC 9 x 5 Propeller (# LP09050)
We have found that the engine runs at it’s best using APC brand props.
They are designed to be very efficient, run quiet at high R.P.M.’s and are
also durable. Use this size prop to break-in your engine, then change to
the prop that best suits your application. Use the guide in the Operating
Instructions to help you find the right size propeller.
q Glow Driver: Magnum Glow Starter w/Meter (# 237438)
The Magnum glow starter is an excellent choice for heating the glow
plug. It uses a Sub-C Nicad, includes a meter to determine the quality
of your glow plug and it also includes a charger to recharge the battery.
It’s a very economical product to purchase and can be used with any
engine that uses a glow plug.
q Motor Mount: Hayes Motor Mount (# 011)
The Hayes motor mount is a glass filled type that mounts to a ply-
wood firewall in the model. It is easy to install and rugged, yet in the
event of a crash, will break away to minimize damage to the engine
and/or airframe.
QUICK STARTING
q Engine Preparation
q 1) Mount the engine to the recommended motor mount. A wood
beam mount built into the airframe would also be sufficient.
q 2) Install the muffler to the engine using the two nuts provided.
The muffler can be rotated to better suit the installation in your model.
Be sure to tighten the two nuts securely to prevent the muffler from
loosening.
q 3) Using a 1/4” drill bit, drill out the center hub in the propeller.
Install the propeller to the engine using the propeller nut provided. Tighten
the propeller nut securely using an adjustable wrench.
q Engine Starting
q 1) Carefully turn the high speed needle valve in completely until it
stops, then turn the needle valve out 2-1/2 turns. This is the mixture
setting for initial starting.
q 2) If hand starting, prime the engine by opening the throttle barrel
completely, placing your finger over the muffler opening and flipping the
prop through compression 2 -3 times. If you will be using an electric
starter, do not prime the engine. The starter will turn the engine over fast
enough to draw fuel on it’s own.
q 3) Connect the glow starter to the glow plug. Open the carburetor
barrel to about 1/4 throttle and start the engine. If you are starting the
engine by hand, you will need to vigorously flip the prop several times
before the engine will start. Once the engine begins running, immedi-
ately turn the high speed needle valve in to keep the engine running.
q 4) Advance the throttle to full while turning the high speed needle
valve in to keep the engine running. The engine should be producing a
very noticeable white exhaust from the muffler and sound like it is run-
ning rough. Allow the engine to run only for about 5 minutes, then shut
the engine off.
q 5) Now that you have started your XL .30RFS engine it must
be properly broken-in. Proper break-in will seat all of the moving
parts, particularly the piston ring and valves. This procedure takes
about 30 minutes of run-time and is highly recommended. An engine
that is properly broken-in will produce more power, be more user-
friendly and last much longer than an engine that does not receive a
break-in period. For this reason we highly recommend following the
break-in procedure detailed in the Operating Instructions before you
run the engine further.
