Symmetrical chassisplate for even flex and torsion, in 7075 T6 aluminium, anodised
and laser engraved. Chamfered edges for more ground clearance when cornering and
countersunk holes. Central slots to mount weight, which can slide into the right
position and then secured.
The 2mm carbon fibre radioplate has multiple functions. It holds the fueltank
in place which is mounted on 3 alu posts in rubber. On the right hand side the
receiver mounts to a nicely shaped carbon fibre plate that connects tot eh radiotray,
sqeezed in right between belt and tank. The throttle/brake servo mounts directly
to the radioplate with nylon spacers and the steeringservo is rigidly mounted
on aluminium posts to the radioplate.
Front flex system
The front section of the radioplate incorporates a flex-control system. You
can either run the 747 with foxes front end, or you can loosen / take out some
of the front upper radioplate screws, and control the flex with the 2 topmounted
Carbon fibre battery-holder positioned between the tank and pipe, for the best
weight balance. The battery is easy to strap down with tape to the bracket.
Durable 75ccm nylon fueltank with transparent material to easy see fuel-content.
Large springloaded quick-fill cap with seal with large tank opening for fast
and easy refills. The bronze sintered filter will keep fuel clean and make sure
tank will empty till last drop if needed. The fueltanks has some small walls
inside to stabilise the fuel, and direct it towards the filter. Some special
made inserts can be mounted inside to reduce contents as needed. Fueltank sits
very low in the car for low center of gravity. Fueltank is mounted with clips
on 3 alu posts with rubber buffers.
Hard Teflon coated threaded shockbodies in high quality aluminium. Supersmooth
o-ring / bushing package, to guide and seal the spring-steel piston rods. Precision
moulded pistons included in 3 types. Threaded pre-load shocknuts in alu with
o-ring inside. Light but strong nylon spring-cups. Tight fitting ball-joints
in top and bottom.
Newly designed lower front bumper with aerodynamic effects and better protection.
Some parts of the lower bumper can be cut open to create more steering. The
upper bumper / bodymount holder connect to the lower one to create a strong
structure to absorb the crashes. The foam elements ( normal or large) can still
be placed but are optional.
3.0mm carbon fibre shocktowers with 3 positions for upper shockmounting. In
the centre you can mount the 3rd bodypost as needed.
A compact and superlight structure of topquality aluminium parts consist of
top-brackets, L and R equal bearing brackets, lower suspension bracket front,
L and R equal FR-RR standing suspension holders and rear, anti-roll bar holder
and Lightened machined alu brackets, equal left and right, toothed section allow
setting belt tension with excenters which seat the bearings. Machined alu topbrackets
L and R version to hold the upper arms. Suspension bracket front . All crafty
machined and grey anodised parts. The open style design allows for very fast
parts exchange as needed, like belt, diff or anti-roll bar.
Strong long double A-arm suspension with aluminium pivotballs, which pivot in
light nylon cups. Medium hard nylon used for the arms to have some flex to increase
grip, and make them most durable. The arms pivot on the inside on springsteel
pins. The pivot-inserts are used to change rollcenter. Small grubscrews mount
in the upper bracket to control downstop. Easy to access and change ride height,
front width, toe-in, caster and camber.
Steeringblocks / wheelaxles / cvd
Very strong nylon steeringblocks with 2 ackermann positions . The spring-steel
wheelaxles are seated in high speed bearings. The light and durable spring-steel
cvds bring all the power to the front wheels. Wheels are mounted to orange
anodised high grade aluminium hex-adaptors using serrated wheelnuts.
Anti-roll bar front
The ballraced wire type anti-rollbar in the front is really easy to access and
change for other type or thickness as needed. The anit-roll bar is linked to
the lower a-arms with a unique pivotball/cup system, which provides direct and
smooth operation and is easy to set.
Servo-saver / steering
The centraly mounted steel servo-saver post fits the spring-loaded ballraced
servo-saver system and steering. The inserts allow 2 ackermann settings. Due
to the open design the linkages with L/R threading can be reached easily. The
whole system allows for very precise steering and minimum bumpsteer.
Middle shaft holder
Machined 2 piece aluminium middle shaft holder, which securely holds the spring
steel middle haft, and doubles up as holder of the pipe-mount.
Very open rear end design with a composition of 8 machined alu brackets, allowing
for controlled flex and easy maintenance. The differential brackets, L and R
equal, are toothed and seat the excentric bearing holder, which allow for setting
belttension. Its very quick and easy to mount a differential and or replace
The 2-speed gearbox shaft holders, double up as anti-roll mounts, and brake
system basis. The holders can be connected to the upper rear brackets in case
less flex is needed. Optional are a a rubber inserts or aluminium inserts. All
topquality machined parts with anodising and laser-engraving.
the low mounted brake system with superlight disk allows for smooth and even
braking, and the open system avoids overheating. The ball-raced excenter and
lever gives a very smooth and direct brake-feeling.
The machined aluminium lower suspension brackets have roll-center inserts with
3 positions to choose from. The rear bracket is the V1 version, whicj is narrow
thanm usee on the 733, to achieve the new geometry together with the near lower
arms and uprights.
Rear carbon shocktower and camber bracket
The 3.0mm carbon shocktower has 3 upper mounting position for the shocks and
it mounts the body-poles. The camber bracket offers 8 positions to choose from,
4 inner and 4 out holes.
The new lower rear arms together with the new uprights create the new geometry
in the rear, to create a wider set-up sweet-spot with more grip and more steering.
The upper camber rods connect to the carbon camber bracket with 8 mounting positions
for roll-center and the camber rod is easy to access and has L/R threading for
fast changes. The aluminium pivotball system allows for fast changes in width
and toe-in. On the lower inside the wishbone pivots on springsteel pins, which
seat with roll-center inserts in the anodised alu suspension brackets.
Lower rear wishbones
the composite lower wishbones feature a mounting position for the anti-roll
bar linkage bracket in carbon, which moves the link position more outside and
higher. Its also offers a mounting position for an optional carbon shock-mount
bracket, to move the lower shockmount position further out, but for the default
set-up its not needed. By placing the lower shock further out, you will get
even more steering .
Uprights / wheel-axles
Durable medium type nylon uprights, which seat the wheel-axles bearings. The
upright offers the mounting position for the steel camber-rod with L/R threading.
The durable spring steel wheelaxles bring to power from the gear-diff to the
wheels. Wheels are fitted on high grade anodised alu wheelhex adaptors and secured
with serrated flanged wheelnuts.
Anti-roll bar rear
The ballraced wire type anti-rollbar in the rear is really easy to access from
the top and change for other type or thickness as needed. The anti-roll bar
is linked to the lower a-arms with a steel rod. The lower arms offers 2 mounting
positions to choose from.

The well proven SL6 gearbox is standard in the 747. Extremely light and compact,
with very low rotating mass. Durable and longlasting gears. High quality bearings.
Very grippy springloaded 2-speed shoes, easy to set.
True Motion Centax clutch
Serpent invented the Centax clutch in the mid 90-ties, and all brands followed
it. Small improvements are found to make the original system even better. The
True Motion Centax has a flat flywheel, and the taper part on the pressure plate.
This allows the flyweights to work even better. The hard anodised aluminium
flywheel has 4 holes to have easy access to keep the flywheel in position when
setting the pre-tension. The flyweights are made of topquality teflon and feature
an additional hole to use grubscrews to make them heavier. The red friction
clutch shoe is very grippy, and works excellent with the steel clutch housing.
The hard anodised gears screw on to the threaded steel bell.
The machined and anodised monotype engine mount has cooling ribs on the sides
and stiffens the chassis as well. The mount perfectly seats the engine, well
alligned. with the gearbox. Small adjustment can be made to move the engine
closer to the gearbox.
