Introduction
The Serpent Cobra
Buggy 2.2 is a result of continuous development and intensive cooperation with
the key team-drivers.
The changes for the 2.2 version are not very big,
but very important to make you go around the track easier and faster.
-
Upright buggy 1/8 V2 (2)
- Wheelaxle buggy v2 (2)
- Driveshaft buggy 98mm
(2)
- Wheel-axle boot rubber (2)
- Antiroll bar front 2.3mm
and
below developments are continued also in the 2.2 version.
- plus 4 chassis:
the hard anodised chassis is 4mm longer in the rear, creating a more stable
rear end, especially better on tracks with short bumps and rough surface. The
great handling on smooth, flat surfaces remains !
- longer alu rear brace:
the longer alu brace also helps to make the rear end more stable. The shorter
nylon or alu version can also still be fitted.
- longer rear central shaft:
to suit the longer chassis a longer rear central shaft is needed (which is
actually the same as the one used in Cobra buggy 1.0 )
- hard coated
shockcaps: the hardcoated aluminium shockcaps can withstand the rigors of
crashes better
- aluminium 14 dgr casterblocks The Cobra buggy has a lot of
steering already which makes it turn very fast. The 14 degree caster blocks
help to smoothen steering out a bit, still lot of steering , but easier, less
direct, creating a more stable front end.
Chassisplate
4mm longer hard anodised chassisplate
in 3mm 7075 T6 aluminium , with machined pockets to create flex make lighter.
Kick-up angle on front for stabile landings. Countersunk holes. Slots to
locate the front and rear suspension mounts precisely. Angled sides to
increase stiffness. Laser engraved Cobra logo.
Bumper
Aligned with chassis kick-up for precise landings and to protect front
suspension holder and anti-roll bar.
Chassis
stiffners
Aluminium longer rear stiffner, and composite front stiffner,
to give extra stiffness, but still allow some flex as
needed.
Central radio / servo mount
Composite radiobox which
offers good space for the steering and throttle -servo, the receiver and rx
battery. The whole assembly including linkages can be taken off easily and
fast in one go, when cleaning the car, or doing maintenance. One extra post is
added close to the servo for stability.
Servo arms and linkages
The
servo arms have a splined insert to have the right fit per brand. The linkages
run very clean and tight and are easy to access to modify
settings.
Suspension brackets
Beautifully machined 7075 T6
suspension brackets in anodized, laser angraved. Precision fit for the nylon
roll center inserts and pivot balls / pins.
Steeringblocks
assembly
Composite steeringblocks combined with 14 dgr black anodised
aluminium C-hubs for precise steering. Composite 10 and 12 dgr c-hubs are also
included. Spring steel wheel-axles with large size bearings and larger inner
with precision threaded aluminum wheel-hubs with offset. Flanged and serrated
wheel nuts.
Front suspension
Durable oversized lower
suspension arms in strong composite nylon. On the lower side the special shaped
downstops screws are mounted. The lower shock-mounting pins are secured with a
small grubscrew from the bottom.
Front anti-roll bar
The
ballraced front anti-roll bar system, consist of a spring steel bend wire,
which is guided through the diff-cases and runs in ballraced steel adaptors.
The wire is linked to the lower suspension arm, with a captured adjustable
threaded pivotball, for very precise and low friction operation and easy
tuning.
Shocktower and bodymounts front
4.5mm thick carbon
shocktower with 5 upper positioning holes for the shocks and and 6 holes for
roll-center positions. 1 centrally located adjustable bodymount , and 2 forward
mounted adjustable bodymounts, all with flip-tops.
Angled steering
system / servo saver
The bell cranks are angled to reduce the angle of
difference between the total caster and steering plane. Therefore you will have
less bump steer and a truer steering Ackerman through the entire range of
suspension
Ackerman plates
With the design of the steering
bell cranks when changing the Ackerman you will not need to adjust your steering
tie rods. You simply will only need to adjust your end points on your
radio.
Rear suspension arms
Durable longer oversized lower
suspension arms in strong composite nylon. On the lower side the special
downstops screws are mounted. The lower shock-mounting pins are secured with a
small grubscrew from the bottom.
Mud-guards
Superlight
polycarbonate mud guards mount to the new lower suspension arms, and will keep
dirt away from your anti-roll bars transmission and wheels.
Rear
uprights v2 assembly
Composite uprights with 3 upper roll-center
positions. Strong steel track-rods with L/R threading and strong balljoints to
pre-set camber. Spring steel wheel-axles with large size bearings and larger
inner ones with precision threaded aluminum wheel-hubs with offset . Rubber
dustcovers in the rear to protect the cvd system and keep the lubrication
inside. Flanged and serrated wheel nuts to guarantee that you will not loose a
wheel nut in a race.
Rear anti-roll bar
The ballraced front
anti-roll bar system, consist of a spring steel bend wire, which is guided
through the diff-cases and runs in ballraced steel adaptors. The wire is linked
to the lower suspension arm, with a captured adjustable threaded pivotball, for
very precise and low friction operation.
Shocktower rear
4.5mm thick carbon shocktower, integrated into the rear section for extra
stiffness, with 5 upper positioning holes for the shocks and 6 holes for
roll-center positions.
Wingmount and bodymounts
rear
Composite rear wing, with strong nylon adjustable rear bodymounts on
wide body-support bridge located far enough to the rear, to support the bodies
in best way.
Captured pivot pins and balls and bolted hinge pins.
All spring-steel hinge pins are either captured or bolted in place and made in
spring-steel quality. This insures your chances to finish an hour long main
event, while battling for the lead. This relieves stress on the hinge pin when
adjusting the kick up, or anti squat. Your pin is free to rotate to any angle
without binding.
Shockabsorbers big-bore 16mm
Hard Teflon
coated threaded shockbodies with 4mm shock-rods. Hard anodized aluminium screw
on hard anodised shock-tops with Serpent laser engraving. Pre-load adjusters
with o-rings inside. Shocks use large diameter membrames and large diameter
o-rings and bushings to create a supersmooth and leak-proof package. Large
diameter pistons are held in place by a nut on the polished shock-rods tops.
Open type spring retainer to let dirt out easy. The shock-shafts are protected
by rubber boots.
