its performance capabilities, the P-51, if not assembled and
operated correctly, could possibly cause injury to yourself
or spectators and damage to property.
2. You must assemble the model according to the instructions .
Do not alter or modify the model, as doing so may result in
an unsafe or unfl yable model. In a few cases the instructions
may differ slightly from the photos. In those instances the
written instructions should be considered as correct.
3. You must take time to build straight, true and strong .
4. You must use an R/C radio system that is in fi rst-class
condition, and a correctly sized engine and components
(fuel tank, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components
so that the model operates correctly on the ground and
in the air.
6. You must check the operation of the model before every
fl ight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not fl own this type
of model before, we recommend that you get the assistance
of an experienced pilot in your R/C club for your fi rst fl ights.
If you’re not a member of a club, your local hobby shop has
information about clubs in your area whose membership
includes experienced pilots.
8. While this kit has been fl ight tested to exceed normal
use, if the plane will be used for extremely high stress
fl ying, such as racing, or if an engine larger than one in the
recommended range is used, the modeler is responsible
for taking steps to reinforce the high stress points and/or
substituting hardware more suitable for the increased stress.
9. WARNING: The cowl included in this kit is made of fi berglass,
the fi bers of which may cause eye, skin and respiratory tract
irritation. Never blow into a part to remove fi berglass dust,
as the dust will blow back into your eyes. Always wear safety
goggles, a particle mask and rubber gloves when grinding,
drilling and sanding fi berglass parts. Vacuum the parts and
the work area thoroughly after working with fi berglass parts.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
DECISIONS YOU MUST MAKE
This is a partial list of items required to fi nish the Sport Scale
P-51 ARF that may require planning or decision making before
starting to build. Order numbers are provided in parentheses.
Radio Equipment
The P-51 requires a minimum 4-channel radio system with
four 44 oz.-in. [3.2 kg-cm] minimum standard sized servos. If
you are installing a glow engine, an additional standard servo
is required for the throttle.
In addition, two 6" [152mm] servo extensions are required for
the aileron servos. If you are using a radio system that does
not support mixing functions, a Y-harness will also be required
to connect the aileron servos to the receiver.
Recommended part numbers for the radio components are
provided below:
❍ Futaba ® S3004 Standard Ball Bearing Servo
(FUTM0004)
❍ Hobbico ® 6" Extension Futaba J (HCAM2000)
❍ Futaba
® Dual Servo Extension 6" J (FUTM4130)
❍ Ernst Charge Receptacle Futaba J FM (ERNM3001)
Power System Recommendations
The recommended engine/motor size for the P-51 is a .40-.55
cu in [7-9 cc] two-stroke engine, .70 cu in [11.5cc] four-stroke
engine, or a RimFire
™ .55 (42-60-480) brushless outrunner
motor. Engine and motor order numbers are provided below:
❍ O.S. ® .46AX ABL w/Muffl er (OSMG0547)
❍ Great Planes RimFire .55 (42-60-480) Outrunner
Brushless (GPMG4715)
If using the recommended brushless motor, a 60A brushless
ESC is required:
❍ Great Planes Silver Series 60A Brushless ESC High
Voltage (GPMM1850)
Propeller
If you are installing a glow engine, choose a prop based on the
engine manufacturer’s recommendation. If you are installing
the recommended RimFire brushless motor, we suggest a
13x10E APC propeller.
❍ APC 13x10 Electric Propeller (APCQ4140)
Batteries and Charger
For a brushless motor installation, two 3350mAh 11.1V Lithium
Polymer battery packs connected in series are recommended.
Order numbers for the battery packs and series connector
are provided below:
