History and Info:

Released by Kyosho in 2018, the 4WD Inferno MP9 TKI4 Spec A 10th Anniversary Special Edition Buggy Kit - # 33013, was produced to celebrate the 10 years of achievements made by the MP9. Each semi-assembled # 33011 model was inspected personally by world champion and model developer Yuichi Kanai. A radio system, engine, starter, fuel, tires and inserts had to be purchased separately, but a pre cut bodyshell was provided.

The model is shaft driven, with alloy plate chassis, 3 x gear type differentials, coil spring over oil filled dampers, anti roll bars, front and rear universal joint drive-shafts, universal joint prop-shafts and a full set of ball bearings.

Buying a Used Kyosho Inferno MP9 TKI4 Spec A
Buggy (and What to look for)

There are essentially three reasons you might want to buy a used Kyosho Inferno MP9 TKI4 Spec A Nitro Buggy; you may be a collector, looking to restore and display it; restore and sell for a profit; or simply restore and race an iconic vintage model. Personally, I used to get a buzz out of restoring an old clapped-out model, installing modern day electrics and maybe a few hop-ups, then showing the gang at our local club, just how competitive those old models could still be.

Has it Got and Instruction Manual?

Cheap, pre-loved bargain models, parts and spares are always coming up for sale, but once you have made your purchase, the one thing you will always need, is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Kyosho website, or purchased separately on eBay. With an instruction manual, any problems with your model Buggy you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
When you receive your used Kyosho Buggy, make a general visual inspection of the chassis, front and rear wishbones, suspension shock towers etc, for any broken parts that may need to be replaced. Then, take a screwdriver and box spanner and check each self tapping screw and nut for security, taking care not to over tighten.

Next, for those Kyosho models with oil filled shock absorbers, remove them from the chassis and dismantle the coil springs. The damper shafts should push in and pull out with a smooth action. If you feel a jolt as you change direction, this means the oil has leaked out and must be topped up. At the same time, change the O-Ring seals to prevent more leakage. Also check the damper shafts for damage. If they are scratched, change them as soon as possible.

Check the Body-Shell

If the body shell of your Kyosho Inferno MP9 TKI4 Spec A is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your Inferno MP9 TKI4 Spec A model, fit an under guard to stop dirt and gravel entering the chassis.

Drive Shafts and Turnbuckles

Titanium Turnbuckles
Examine the drive shafts for wear and replace as required. If possible, change them for titanium. The steel shafts wear and bend too easily.

If you intend to race your Inferno MP9 TKI4 Spec A Buggy model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

Examine the Drive System

The gearbox of your used Buggy should be opened up to check for gear wear and lubrication. A thin coat of grease is often used on internal gears and although this is fine for basic running around on the back yard, if you intend to race your Buggy at a higher level, this should be removed and replaced with racing oil (ZX1 or Teflon Oil). Of course, this should be reapplied after each race meeting.

Pinions and Spur Gears

Gears are a weakness on all Buggy RC models. Head on collisions can easily damage the gear teeth on nylon and plastic spur gears. Heavy impacts can also loosen the nuts or self tapping screws that hold the Nitro Engine in Position, allowing the pinion gear to pull out of mesh slightly and rip the tops off the teeth on your spur gear. To minimise this possibility, fit bolts with locking nuts to the Nitro Engine mount and remember to check them for security after every two or three runs.

Don't Neglect the Ball-Joints

Ball joints always cause problems. For top level Nitro Buggy racing, the plastic ball connectors should be checked and if deemed necessary changed after every meeting. A simple thing like a loose fitting connector popping off could easily end your race, so better safe than sorry.

Steering Servo and Servo-Saver

Servo Gears
The Inferno MP9 TKI4 Spec A steering servo is also prone to damage. In high speed crash situations, the fragile gear teeth of the servo can be broken off, rendering your expensive servo useless, so be sure to obtain a good quality "Servo Saver". Check out my Servo Information article.

Stabilizers

If body roll on your Kyosho Inferno MP9 TKI4 Spec A is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers.

Don't Forget those Bearings

If your used Kyosho Buggy comes with plastic and sintered brass bushings (ring type bearings), check the shafts that run in them for wear. Dust and grit can get into these bearings and abrade the shafts. Therefore, you should replace them all with shielded ball bearings. If the model has been run with ring type bearings, you may have to change all the axles and driveshafts. For more information, take a look at my article, How to get the best from your Bearings.

Finally, good luck with your Inferno MP9 TKI4 Spec A model and good racing.

Hints, Tips and Information

Maintain your Fuel System

   Nitro engines need a regulated constant supply of fuel to run efficiently. If this supply is restricted or contaminated in any way, the engine will show problems in a number of ways.

   If your engine is running hotter than normal, begins to stutter, has trouble idling or won't even start, your first instinct would be that it is running lean, but when you try to make adjustments, it has no effect. The reasons for your problem could be a number of things, but the most likely is a fuel or fuel line problem.

   First of all visually inspect the fuel system. Check the fuel line for any kinks or tight bends that could restrict free flow. If you do find any kinks or any damage to the line, I would recommend changing it rather than trying to simply straighten it out or repairing it in any way. Any leaks you find in the system must be dealt with, if you can, replace the parts.

How to Reduce the Weight of your RC Model Car

   If you ever step up and enter a regional, national or international event in RC, you will find one specific rule concerning the weight of your car.

   At the time this article was written, the Minimum weight restrictions for 1:10 electric Touring Cars at different events, was between 1350g and 1500g. This includes your Motor, ESC, Receiver, Battery, Body Shell and the transponder.

   Out of the box you will find the majority of 1:10 Touring Cars, with everything onboard, are way over this Minimum weight, and unless you are good enough to attract sponsors, getting your car down to anything approaching that minimum weight will be very expensive.

   There are things you can buy like micro ESC, and Receivers. But Batteries and Motors are what they are, and you have to work around them.

   To reduce the weight of your chassis, there are a number of things you can do.
