Buying a Used Himoto Warrior MXT-5
Monster Truck (and What to look for)

There are essentially three reasons you might want to buy a used Himoto Warrior MXT-5 Nitro Monster Truck; 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.

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 Himoto website, or purchased separately on eBay. With an instruction manual, any problems with your model Monster Truck you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
When you receive your used Himoto 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 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.

Check the Body-Shell

If the body shell of your Himoto Warrior MXT-5 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 Warrior MXT-5 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 Warrior MXT-5 Monster Truck 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 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.

Pinions and 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.

Don't Neglect the Ball-Joints

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.

Steering Servo and Servo-Saver

Servo Gears
The Warrior MXT-5 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 Himoto Warrior MXT-5 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 Himoto 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 Warrior MXT-5 model and good racing.

The Importance of Balancing your Model Car Wheels

   The day I passed my driving test at the young age of 17, the first thing I did was to drive over to my girlfriends house and take her out to a long straight stretch of road close by, where the boy racers would often congregate. No one was around that day, so the road was relatively quiet. I slowly went through the gears and we were soon up to 65 with no problems, but as we got closer to 70, my hands began to sense a small vibration on the steering wheel. By the time we hit 75, the steering wheel and the whole car was vibrating wildly. My girlfriend was hysterical, screaming for me to "slow down!" I did of course and tried to calm her down.

   Back home I told my dad what had happened. He then reminded me that just the week before we had put on a new set of front tires and suggested the wheels were probably out of balance. Sure enough, after the wheels were re-balanced, at 85, 90, the car was steady as a rock and drove perfectly.

   As I got deeper into RC, that memory returned and I realised to be more competitive I would have to balance all my wheels.

How I Balanced my Model Car Wheels

Wheel balancing equipment for RC cars is now available on line and from most RC model shops, but back then I had to make my own using the rear end of an old Tamiya F1 car.

Choosing the right Tire Inserts

Once upon a time, all RC model tires were equal - they were all trash. None of the old tires had any kind of internal support, because the hard compound they were made of didn't need it. But that was before the newer soft compounds were developed. These new tires were so soft that if some kind of insert was not used they would just lay flat under the weight of the car. Thus, the new science of tire inserts was born.

Inserts for Off-Road Tires

The basic soft foam inserts that come with many off-road rubber tires can be in one of two types. They can be basic rings of sponge, or the cheap and nasty strips of sponge. Many of the latest foam inserts now come pre-shaped, but more than often, they will need some work done to them before they are inserted into the tires.
