Kyosho Inferno MP9 TKI4 Nitro Buggy

Kyosho Inferno MP9 TKI4 Nitro BuggyJust a few days after posting a teaser picture of the car, Kyosho officially unveils the new Inferno MP9 TKI4 Nitro Buggy! Features include a new body with improved aerodynamics, lighter wing with wickerbill attachments for additional tuning options, reinforced suspension arms, 2mm longer front suspension arms , new low profile wing mounts, new front suspension mounts with reduced skid angle, a heavy duty servo saver assembly, 93mm driveshafts, redesigned steering knuckles, new aluminum rear hubs, lightweight shock mounting pins, stronger 4mm hingepins, a more secure air filter housing, heavy duty ball ends and a lightweight 13t clutch bell. The Kyosho Inferno MP9 TKI4 is expected to hit store shelves next month.

Body
The new body shell features a much longer cab than the TKI3. It has a longer, flatter roof to produce more laminar airflow across the roof and on to the rear wing. The cab is farther forward (cab forward), more narrow and features a more upright windshield. Downforce features on the side pods of the Inferno MP9 TKI4 body have also been moved forward. These changes to the body produce more front downforce, which results in improved handling.

Wing
Much attention has be given to the new rear wing design, and for good reason. After the introduction of a few vacuum-formed wings, extensive testing showed the reduced weight was of value, but the polycarbonate material is lacking durability. So, a new wing is included in the Kyosho Inferno MP9 TKI4 kit that features much thinner construction for similar weight savings, but it’s more able to handle a crash and survive. Two additional vertical planes have been added and two different size wickerbills are included for more or less rear downforce.

Hinge Pins
A delicate balance is required when choosing materials for the hingepins. Too hard and it snaps – too soft and it bends to easily. The lower pins now benefit from material chosen based on 30 years of off-road nitro experience. They’re stronger than the pins in the TKI3.

Driveshafts
Previous versions of the MP9 have used various length universal driveshafts. The Kyosho Inferno MP9 TKI4 version uses uniform 93mm front and rear universal driveshafts. It’s the ideal length for the new front suspension arms. You no longer need to carry two different length driveshafts as spares.

Servo Saver
High performance servos are only as effective as the inline servo savers in 1/8 off-road buggies. As a top-of-the-line race car, Inferno TKI4 customers are expected to install high-performance servos, therefore, the optional heavy-duty servo saver with the lightweight adjuster is included.

Receiver Box
Getting all the wires into the receiver box can be a challenge with the new, heavier wires being used on high-performance servos. The opening for the servo wires and other accessories is now larger to accommodate not only the servos, but leads for items such as telemetry sensors and transponders.

Shock Pistons
These shock pistons have been thoroughly tested in a wide variety of conditions. They produce a little bit less “pack” and smoother, more linear damping than the previous shocks. They’re notably better on tracks with a lot of little bumps and tracks that degrade over time and develop divots. The initial damping of the Inferno MP9 TKI4 shocks is much more responsive, which provides better traction and a greater sense of confidence for the driver on difficult surfaces.

Shock Boots
Kyosho faithful may recognize the overall look of the TKI4’s shock boots as that of the 777 shocks. They are in fact, a similar design that dispenses with the “accordion” style boot. The straight boot has proven to more durable and effective than the dust boot that’s been used on all previous versions of the MP9, so the latest car will include the straight dust boots.

Wheel Nuts
Standard wheel nuts have been standard equipment on previous versions of the MP9 – nylon lock wheel nuts were optional. The Kyosho Inferno MP9 TKI4 will include matching gun-metal anodized, nylon-locking wheels nuts as standard. They require far less torque on the wheel nut to ensure they’re secure.

Steering Knuckles
Shorter steering arms on the new steering knuckles changes the Ackerman angle, which promotes increased corner speeds. By maintaining more correct Ackerman angle throughout the range of steering motion (especially at higher degrees of steering angle), there’s less slip angle, which means the TKI4 carries more corner speed than ever before.

Turnbuckles
The increased arm length and the addition of the new steering knuckles, makes longer steering turnbuckles a necessity.

Shock Pins
The lower shock mounting pins previously had a flat spot that needed to be indexed to the set-screws that secured the lower shock mounting pins. The new pins have a lightened head (every little bit counts) and there’s a groove machined around the entire circumference. That means the pins no longer need to be aligned, and the lower end of the shocks are now more secure than ever.

Rear Hubs
New aluminum rear hubs feature eccentric inserts to increase the number of roll center options available. The upper linkage rod has an upper and lower mounting position, and now the inserts on the new rear hubs provides intermediate adjustments of just 1mm. This give the racer four different settings instead of two.

Hingepin Angle
It’s easy to see the difference in the height of the new hinge pin braces on the rear of the front bulkhead. Those included in the Inferno MP9 TKI4 raise the rear of the front hinge pin, reducing the hinge pin angle. The reduced hinge pin/arm angle reduces the amount of dive during corner entry, and significantly improves on-power steering during corner exit.

Air Filter
Loose air filters are the number one killers of engines, and the filter and filter housing of the Kyosho Inferno MP9 TKI4 is designed to best protect your favorite racing engine. The new air filter housing is more substantial than the previous version, and it better secures the foam filter elements to protect the engine. The assembled filter also has a new, more secure mount that will ensure the filter remains in place throughout the roughest A-finals in the world.

Ball Ends
The ball ends used on the steering turnbuckles have been made stronger. The wall thickness of the ball ends is increased to keep the fit very tight and strong to reduce wear and increase reliability.

Clutch Bell
A lightweight 13T vented clutch bell is now standard in the Kyosho Inferno TKI4 . Lighter rotating mass is important in terms of quicker acceleration and improved fuel economy. The clutch also benefits by reducing the heat in the clutch shoes and springs, and by allowing the clutch debris to escape from inside the clutch bell.

Suspension Arms
The lower rear suspension arms benefit from significantly increased webbing around the gussets in the arms. The arms have been reinforced in the web area to make them especially stronger in line with the hinge pin, while still allowing some necessary flex in the perpendicular axis to make shock set-up a LOT easier. Arms that are simply made super stiff in every direction will make the car very difficult to tune properly because there’s such a small tuning window. The new MP9 arms add strength and durability in the right areas, while still providing a car that’s easy to set-up for your conditions and driving preferences.

Front Arms
Like the rear suspension arms, the front arms benefit from all the reinforcing to make them stronger. The front arms are also 2mm longer in than the Inferno TKI4 front arms, which allows the use of the 93mm driveshafts. The longer arms also bring the front suspension out closer to maximum width as regulated by world and national organizations, which gives the TKI4 a wider stance for improved cornering.

Wing Support
Extensions visible on the outside of the wing mounts helps to support the new, lighter rear wing and reduces the likelihood of damage in the event of a severe crash. The wing mount is also lower, which keeps the wing at the proper height in relation to the new body, and by keep it lower, it also reduces the possibility of damage in a crash.

Wheels
The Kyosho wheels for the already come in a variety of colors, but they’ve been retooled to be lighter and the match the dimensions of the most popular wheels and the most popular tires. That means the new wheels will ideally fit all the most current racing tires, and they’ve even been modified to include a rougher surface that will make the glue bead much stronger, which will ensure that your tires remain attached to the wheels.

Preload Adjusters
Apart from being black anodized, the new spring pre-load adjusters feature indexing marks, which serve as a visual reference for more accurate spring pre-load adjustments .
