Buying a Used Kyosho FO-XX VE
Monster Truck (and What to look for)


   Buying a used Kyosho FO-XX VE Electric Monster Truck, or any used RC Model, has a number of advantages. It is generally cheaper than new, ready built and may come with a variety of expensive hop-ups already installed. Cheap, pre-loved bargains are always becoming available. However, depending on the age of your purchase, it may need a little tender loving care before you can take it out on the back yard.

   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 Monster Truck you may discover can easily be fixed.

Dampers
   When you receive your used Kyosho Monster Truck, 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.

   If the body shell of your Kyosho FO-XX VE 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 FO-XX VE model, fit an under guard to stop dirt and gravel entering the chassis.

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 FO-XX VE Monster Truck model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   The gearbox of your used Monster Truck 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 Monster Truck 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.

Spur Gears
   Gears are a weakness on all Monster Truck 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 Electric Motor 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 Electric Motor mount and remember to check them for security after every two or three runs.

   Ball joints always cause problems. For top level Electric Monster Truck 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.

Servo Gears
   The FO-XX VE 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.

   If body roll on your Kyosho FO-XX VE 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.

Ball Bearings
   If your used Kyosho Monster Truck 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 FO-XX VE model and good racing.

Information and Advice

Electronic Speed Controllers

History:

   ESC were originally developed to be used in conjunction with brushed 27T stock and modified motors in the late 1970s, early 1980s. Compared to modern day Controllers, they were Bulky and heavy, constructed using basic resistors, rheostats, capacitors and transistors, crammed together on a simple circuit board, to provide stepped but smooth acceleration when compared to the old mechanical, servo operated sweeper Speed Controllers. An Electronic Switch to change the direction of current flow was used on some of these early ESC to give reverse operation. Although they were a vast improvement on the old mechanical speedos of the time, they were expensive, jerky to control and prone to burn out if not carefully looked after.

   As new technology became available, improvements were slowly made and with the introduction of the new FET (Field Effect Transistors) and some basic mass produced silicon chips, ESC were made smaller and their reliability gradually improved.

   By the mid 1990s, "regenerative breaking" was developed. This meant that energy that would have been lost slowing down the car by effectively turning the motor into a generator, was harvested and put back into the battery. This of course was long before F1 had KERS (Kinetic Energy Recovery System) and adjustable anti lock breaking was introduced.

   Brushless Motors came to RC in the late 1990s early 2000s, which required a new breed of ESC to be developed to fully utilise the new technology. Ni-Cad Rechargeable Batteries were superseded by Ni-Mh and more recently Li-Po Batteries which provided higher Current output for the ESC to regulate. The latest ESC now use sensors to manage the motor and can be adjusted remotely to suit varying conditions.


Brushed Motor ESC.

   The "Silver Can" Stock Motors that come in a wide number of RC model kits are often accompanied by a 5 Amps to 20 Amps ESC. However, if you want to upgrade to a more powerful Modified Brushed Motor, 20 Amps may not be enough, so you will have to buy a something well over 20 Amps depending on the number of turns of your motor. As a rough guide, a 9 Single has a much higher current requirement than 20 Single.

Brushless Motor ESC.

   ESC for Brushless Motors are in no way compatible with brushed motors. The DC (Direct Current) input from the battery, on brushless ESC is transformed into three phase AC (Alternating Current). Each "phase" connecting three wires on the Brushless motor. By changing the frequency of the output wave the motor will spin faster for acceleration or slower for breaking. Reverse is simply achieved by changing over any two of the three "phases".
   At the time this article was written, Brushless ESC range from 3 Amps to around 300 Amps.
   For beginners I recommended you buy an ESC and Motor Combo, that way you can be sure the ESC Current rating is correct for the Motor.

Hints and Tips

Slipper Clutch and Hydra-Drive

   More often installed on off road RC Models, the Slipper Clutch has been around since the late 1990s. Basically the idea is to prevent wheel spin and increase traction under acceleration, to improve the cars stability from a standing start, when landing from jumps or on corner exits. It also protects the spur gear and drivetrain, to some degree, when using a high torque motor.

   The design is quite simple, employing two independent metal plates, one generally fixed to the spur gear and the other to the drive mechanism, clamping onto a fibre or rubber ring or pad. Adjustment is commonly achieved by slackening or tightening a spring loaded nut on the end of the spur gear mount.

   Setting up the slipper clutch can take some time and is a matter of individual preference, but normally the way to do this is from a standing start, jamming on the throttle and simply getting the feel of the car for that particular surface, being grass, gravel or dust. Personally I adjust it to give me around a metre and a half slip, before it achieves full drive. Wear on the slipper clutch is natural and often has to be readjusted after each race.

The Hydra-Drive


   The Hydra-Drive, or Fluid Coupling design was actually designed in the 1950s, but only came to RC a couple of years after the introduction of the slipper clutch. In principle, the Hydra-Drive is supposed to give similar results to the slipper clutch but need less continuous adjustment. In practice, for me anyway, it was not easy to live with.

   Hydra-Drives employ two independent impellers, immersed in silicone oil and enclosed in a sealed housing. Again, like the slipper clutch, one impeller is fixed to the spur gear, the other the drive. As power is applied, the spur gear will spin its impeller, until through the oil, drive is picked up by the drive impellor. The only real way to adjust the drive was to change the oil viscosity, or in some, the gap between the impellers could be adjusted by shims. All this took time and as far as I am aware, the Hydra-Drive is no longer used in RC.
