AMA RULES & REGULATIONS
1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airwor-
thy by having been previously, successfully flight tested.
2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will
give right-of-way and avoid flying in the proximity of full-scale aircraft. Where necessary, an observer shall be utilized to supervise flying
to avoid having models fly in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the flying site I use, and I will not willfully or deliberately fly my models in a
careless, reckless and/or dangerous manner.
4) The maximum takeoff weight of a model is 55 pounds, except models flown under Experimental Aircraft rules.
5) I will not fly my model unless it is identified with my name and address or AMA number on or in the model. (This does not apply to
models while being flown indoors.)
6) I will not operate models with metal-bladed propellers or with gaseous boosts, in which gases other than air enter their internal
combustion engine(s); nor will I operate models with extremely hazardous fuels such as those containing tetranitromethane or hy-
drazine.
1) I will have completed a successful radio equipment ground range check before the first flight of a new or repaired model.
2) I will not fly my model aircraft in the presence of spectators until I become a qualified flier, unless assisted by an experienced helper.
3) At all flying sites a straight or curved line(s) must be established in front of which all flying takes place with the other side for
spectators. Only personnel involved with flying the aircraft are allowed at or in front of the flight line. Intentional flying behind the flight
line is prohibited.
4) I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission. (Only
properly licensed Amateurs are authorized to operate equipment on Amateur Band frequencies.)
5) Flying sites separated by three miles or more are considered safe from site-to site interference, even when both sites use the
same frequencies. Any circumstances under three miles separation require a frequency management arrangement, which may be
either an allocation of specific frequencies for each site or testing to determine that freedom from interference exists. Allocation
plans or interference test reports shall be signed by the parties involved and provided to AMA Headquarters. Documents of agree-
ment and reports may exist between
(1) Two or more AMA Chartered Clubs, (2) AMA clubs and individual AMA members not associated with AMA Clubs, or (3) two or
more individual AMA members.
6) For Combat, distance between combat engagement line and spectator line will be 500 feet per cubic inch of engine displacement.
(Example: .40 engine = 200 feet.); electric motors will be based on equivalent combustion engine size. Additional safety requirements
will be per the RC Combat section of the current Competition Regulations.
7) At air shows or model flying demonstrations, a single straight line must be established, one side of which is for flying, with the
other side for spectators.
8) With the exception of events flown under AMA Competition rules, after launch, except for pilots or helpers being used, no powered
model may be flown closer than 25 feet to any person.
9) Under no circumstances may a pilot or other person touch a powered model in flight.

Pushrod assembly (parts 4 through 6) is already assembled but check that the length is actually
43mm (center to center). As the pushrods are built and installed they should be checked for
tightness. Press one ball link onto each double studded steel ball, making sure that pressure is
applied from the side of the ball link with the circle mark. While holding one flybar control arm, ap-
ply a small amount of Medium threadlock and thread one end of the double studded steel ball into
each standoff. Do the same with the other flybar control arm tiebar. Slide and center the flybar
through the head assembly. Carefully look at the flybar control arm assemblies from the previous
step and notice that when installed correctly, the securing set screw is on top. Insert one flybar
control arm cushion against each bearing and then slide the control arm halves onto each side
so that they match together and the set screw remains on top. Insert one M3x12 button head
socket screw to secure the opposite standoff.

Thread the flybar paddles onto the flybar until the mark is reached and align
the paddles parallel. Again using the ruler, rotate one paddle or the other to
get equal distances while remembering the leading edge of the paddles will be
turning clockwise.

Drop some Medium threadlock into the side of
the blade grip. Place the grip arm over the grip
and install the M3 button head screws as shown
with washer. Slide the M3x18 button head screw
through the bell mixer arm from the flat side, add
one M3x5x3 spacer and apply a drop of Medidum
threadlock to the end of the threads before in-
stalling into the blade grip. Tighten the bolt
until there is no end to end movement,
but do not overtighten the bolt as you
can strip out the hole or bind
the bearings. Make two
assemblies.
BELL MIXER RATIOS

There are two types of dampeners provided. The hard black plastic dampeners
(HI6520A) should only be used for hard 3D flying. If using the hard plastic dampeners,
use only one of the (HW6182) 8x13 spacer. Press in the head dampers into the rotor
head block. Lubricate the inside surface of each damper with light oil. Press one M8x16
ball bearing into both ends of each main rotor blade grip. Slide
one M14 thrust washer against the bearing closest to the
main rotor blade. Make sure that the bearing and
the thrust washer are properly seated into the
deep end of the blade grip. If necessary use
a socket that matches the outside
diameter of the bearing and
press into position. Make
two assemblies.
Press one M3x7 flanged ball bearing into one
side followed by one M3x5 spacer and another
flanged bearing from the opposite side. If the bear-
ing is tight, lightly sand the bell mixer and use Red
threadlock to bond the bearing in place. Install the
CNLR1014 short steel ball into the single hole side of
the bell mixer and install the CNLR1020 medium steel
ball using Blue threadlock. Install the medium steel ball ac-
cording to the table to suit your flying preference. Make two
assemblies.

Make sure you install the ball links onto the
steel balls in the correct direction. The pro-
vided measurements are measured from the
center of the whole on the plastic ball links.
These measurements are the same for all fly-
bar versions of the Radikal G30 heads. These

Attach the cooling shroud mounting plate first, making sure it is installed in the correct po-
sition. The drilled beveled holes must match with the bevel head screws. Clean the crank
shaft on the engine with alcohol, then apply a very small coating of oil to the crank shaft
prior to installing fan/clutch hub. Once you have the fan assembly installed onto the motor,
tighten the M2.5x8 screw on the bottom of the hub. Be gentle as not to over-torque this
screw. This screw is used to center the hub and is not the anchoring screw that holds the
hub to the engine. Next, install the M6.5 washer and M6x13 bolt.
Bearing is pre-installed
Once the clutchshoe is mat-
ed with the clutchbell, the
clutchshoe should protrude
about 1mm from the bot-
tom of the clutchbell. Use
6.5x13x1 shims if neces-
sary to raise the clutchshoe
up if it’s protruding more
than 1mm.
Do not overtighten
Build the fan by placing Medium threadlock into the threaded
holes on the fan hub (#16). Attach the fan to the hub as shown
and install the M3x6 flush head cap screws making sure the
screws fall into the beveled hole on the fan.
When tighten-
ing the M6x13 bolt,
you can use a piston locking tool
(Part Number #CN2155Z) made for
gasoline engines.This will allow you to torque
the bolt without the engine spinning. NEVER grab
the bottom of the crank shaft where the starter attaches
and tighten the bolt holding fan/clutch hub.

When installing the engine assembly to the frames, do not tight-
en one side all the way leaving the other side completely loose.
Tighten the M4x20 bolts on either side of the frames evenly
moving from one side to the other. Make sure to apply medium
threadlock to these bolts prior to installation. After you have
installed the left and right M4x20 bolts, install the front engine
block making sure to use medium threadlock on the M4x20
bolt holding the engine’s head in place. Dry fit the M3x8 button
head screws holding the clutch assembly. Leave these loose
until the next step.

Drop some medium threadlock into the
four holes on the driven tail hub. Then
use the M3x6 flush head cap screws
and install through the tail drive gear
tightening onto the driven tail hub.
Make sure to use threadlock sparingly
as to not get excess threadlock onto the
plastic gear. Apply medium threadlock
to the six holes on the dual bearing au-
to-rotation hub and install the gear onto
the hub. Then using the M3x8 flush
head cap screws torque down onto the
main gear. Make sure the flush head
cap screws are installed onto the con-
cave beveled side of the screw holes on
the main gear.
Be sure to clean the inside and outside of the main shaft
sleeve with alcohol prior to installation.
For the roller bearings, we recom-
mend a very light oil. The oil MUST-
NOT attack/break down plastic as
this could damage the cage in the
one-way bearing. Prior to applying oil,
make sure to clean the roller bear-
ings with a cotton swab making sure
there is no debris in the bearings.
If in the future your one-way bearing or
sleeve is worn or damaged, it is highly
recommended to replace the sleeve and
one-way bearing hub at the same time.

Apply grease to the thrust bearing. Place the
Main Gear assembly into the frames. Insert
the main shaft with head assembly through the
bearing blocks while lining mast stopper while
going through the Main Gear assembly. Line
up the hole in the Main Shaft with the hole on
the Driven Tail Hub. With the help of needle
nose pliers or hemostats, place the Pin (#3)
through while making sure you have it going
through the Main Shaft. Install the two M4x4
set screws making sure you have them evenly
threaded on both sides. When installing the
Mast Stopper (#2), make sure it is pushed up
to the top prior to tightening the M2.5x8 Cap
Screw. DO NOT OVER TIGHTEN.
