History, Info (and How To Set-up Tips) for the EXO-16:


  Introduced by Himoto Racing circa 2008, the 4WD EXO-16 Touring Car - was available with a 380 brushed motor - # HI4182 - or with a brushless motor - # HI4182BL - ESC and radio system.

  The model was shaft driven, on a molded plastic double deck chassis, with gear type differentials, coil spring over oil filled dampers, dogbone drive-shafts, bushings and ball bearings.

  This is the same model as the HSP Racing Zillionaire.

Buying a Used Himoto EXO-16
Touring Car (and What to look for)


   Buying a used Himoto EXO-16 Electric Touring Car, 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 road.

   The one thing you will always need is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Himoto website, or purchased separately on eBay. With an instruction manual, any problems with your model Touring Car you may discover can easily be fixed.

Dampers
   When you receive your used Himoto Touring Car, 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 Himoto 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 Himoto EXO-16 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 EXO-16 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 EXO-16 Touring Car 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 Touring Car 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 road, if you intend to race your Touring Car 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 Touring Car 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 Touring Car 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 EXO-16 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 Himoto EXO-16 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 Himoto Touring Car 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 EXO-16 model and good racing.

Hints and Tips

Roll Center

   One of the least understood settings on RC model cars is concept of roll center. The simple definition of roll center is a point in space that the chassis rolls from side to side as the car maneuvers around a corner.

   To calculate roll center you have to consider things like the height of the axles, the inside and outside camber link positioning, the length of the suspension arms and the location of their inside pivot point. Sounds complicated doesn't it and in truth it is.

   On all RC model cars, most of the cars weight is above the chassis and the center of gravity of the car is not only from front to rear, but also from top to bottom. This point is called the "true" center of gravity and is the point around which the weight of the car will want to roll from side to side, but it is the roll center of the chassis that the chassis will actually roll around, not the center of gravity.

   Once you have determined the positions of roll center and center of gravity, you can calculate the "roll moment". It is this that determines how easily the chassis will roll from side to side.

   But what does all this mean? I hear you ask. Well, it gives you some insight to what changing the position of your camber links can do to the way your car handles.

   Lowering the outside camber links, lowers the roll center, so conversely, raising the outside link position raises the roll center.

   Lowering the inside camber link position raises roll center and raising the inside camber link position, lowers the roll center.

   Any of these adjustments will affect the "roll moment" and therefore you have some control of body roll.

   The length of the camber link bars affects the speed of roll center change as the car driver around corners. Longer links increase the rate of change. Shorter links decreases the rate of change.

   Adjustments to the roll center will change the way the car reacts in a number of ways.

   Lowering the front roll center gives more steering under acceleration, but the car is less responsive. Ideal for smooth high grip tracks, with long sweeping corners.

   Raising the front roll center provides less steering when accelerating out of the corner, but the car feels more responsive and is less prone to traction roll. Best for high grip twisty tracks.

   Lower rear roll center improves grip under acceleration, but reduced grip when breaking. Helpful to avoid traction roll as you enter the corner and tracks with low grip to increase traction.

   Higher rear roll center gives you less under acceleration, but the car is more responsive. Works for high grip twisty tracks to reduce traction roll.

Hints and Tips

Soldering Battery Packs

   Nicad and Nimh batteries sometimes come as six separate matched 1.2 volt cells. These of course have to be soldered to each other in series to produce either a side by side stick pack, or a two times three cell saddle pack.

   Special copper, or silver plated straps must be used to make up these packs and each strap must be prepared before attempting to solder it to the battery cell, by placing a blob of solder at each end of all the straps needed.

   A jig to hold the cells vertical and side by side is advisable. Using electrical solder, with a flux core (flux aids the flow and adhesion of the solder) heat your soldering iron to as hot as it will go. Then with the stick of solder touching on the end of the cell, touch it with the iron. What you want it to spread evenly on the central part of the pole of the cell. Count to 3 seconds. If it doesn't melt the solder in that time, your iron is not hot enough. Battery cells are notoriously very fragile and susceptible to the very high temperatures soldering requires. Anything longer than four or five seconds direct contact with the iron can cause damage to the crystal structure in the cell, so be wary.

   When you have solder on each end of each cell, line them up in the jig, positive to negative and dab a spot of flux on the soldered cells, then position your straps, with the solder coated side faced down, touching the solder on the end of the cell. Now place your hot iron on the strap. Heat will transfer through the strap and melt the solder on the two faces. Again, count to 3 and you should feel the strap drop slightly as the solder fuses with the solder on the cell. Repeat this for each cell on both sides to produce your desired configuration. Finally solder your two wires, previously prepared with connectors, to the pack. Do not solder wires with bare ends to your pack. If these wires were to touch and short out, you could effectively kill your expensive battery pack I use Red for positive and Black for negative, but so long as you know which is which electrical equipment does not like the battery to be connected the wrong way.
