Buying a Used CEN Genesis 46
Monster Truck (and What to look for)


   Buying a used CEN Genesis 46 Nitro 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 CEN 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 CEN 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 CEN 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 CEN Genesis 46 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 Genesis 46 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 Genesis 46 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 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.

   Ball joints always cause problems. For top level Nitro 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 Genesis 46 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 CEN Genesis 46 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 CEN 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 Genesis 46 model and good racing.

Hints and Tips

Decals

   After spending lots of time and effort to paint your bodyshell, you come to the point where you make it look good by putting on all those flashy decals, but before you rush in with the scissors and start cutting, there are a few things you should do first.

   Good preparation is key to a perfect job, so before you do anything with your decals, you must first of all wash your hands and then make sure the bodyshell is clean and no oil or grime from your previously grubby fingers remains on the Polycarbonate Lexan surface. Methylated spirits is the thing to use, or failing that, use one of those wipes you use for your computer monitor screen. As the body shell dries, you can carefully cut out the decals from the sheet. Do the big ones first and leave the smallest ones for last.

   Now you can prepare to the decals for positioning. Carefully remove the backing paper from the decal with your thumb nail and then put it back on again, but slightly out of line. Place the decal in the position you want it on the bodyshell and when you are satisfied, press down the sticky corner onto the bodyshell and peel off the backing paper, following it along with your fingers to avoid any bubbles. Repeat the process until all your decals are in place.

   Any bubbles or misfitting areas can be corrected by using a sharp modelling knife to carefully pierce the bubbles, or score the poorly fitting area and complete the process with your finger nail.

   Some misalignments can often be fixed using a hair dryer on the offending decal to soften the glue enough to allow you to reposition it, but be careful; Lexan can react like heat-shrink and may wrinkle if you use too much heat.

Hints and Tips

Gearing to Win

   Just because you have the latest model, the best available batteries, the most powerful electric motor or nitro engine, doesn't mean you will go out and win everything in sight. The fastest car on the track is rarely the one that wins, it's the one that can accelerate out of corners under control and remains consistent and efficient from the start to the end of a race.

   In days gone bye, all you had to consider was the number of mili amp hours (Mah) in your battery and the current draw of your high powered motor. Gearing for a five minute race was a balancing act. But with the development of the new high capacity batteries, brushless motors and smart ESC, all that changed. Now, gearing is more of a matter of what suits your driving style and how quick your reflexes are on the sticks, the trigger and steer wheel of your transmitter. So, where do you start?

   At your local club track, you quickly find the right combination and set-up for your car by talking to the more experienced members. After a while, as your knowledge grows, tweaking a few things here and there can give you that small edge to keep you competitive. So, it follows that on tracks you don't know, you should talk to the locals there, who may be racing a similar model to your own and adjust your set-up to suit.

   Gearing correctly for any given track is absolutely crucial if your car is to be competitive.

   Too high a gearing may get you in front at the start of a race, but as your motor begins to overheat and lose efficiency, that initial advantage will soon be lost.

   Too low a gearing and although it may get you past your opposition accelerating out of the corners, you will loose that place again on the fast straights. Gearing low will always get you to the end of the race, but it will hardly ever get you on the winner's rostrum.

   Having said that, on tracks you don't know, initially it's always best to err on the side of low gearing. For your first practice laps on a new track, choose a motor that has a reasonable current draw and with a fully charged battery, try a race length run, learn the corners what line to enter and exit, where you can accelerate to overtake and how fast you need to be on the straights to keep up (not overtake) the opposition. After your practice race, check the remaining capacity in your batteries and the temperature of your motor, (keep records of each motor and discover at what temperature a specific motor loses efficiency all this helps when selecting the right gearing.)

   Armed with this knowledge you can then consider how to alter your gearing.

   If the motor is cool (in comparison) and your battery has ample remaining charge, try a larger pinion perhaps one or two teeth more. Don't overdo it.

   An overly hot motor and low remaining capacity battery speaks for itself. The race timed practice run should have given you an insight to this problem. Obviously, in this instance you must use a smaller, less teeth pinion, or start again with a milder, less powerful motor.

   If the motor is hot, but not too hot, the battery has ample remaining charge and you did not notice any drop in efficiency towards the end of your practice run, then you are close to the optimum set up for that particular motor.

   Depending on how competitive that set-up is, you can stick with it, maybe tweak a tooth up or down, or repeat the process with a different motor to get you where you want to be.
