Buying a Used Hong Nor X2-CRT Truggy (and What to look for)


   Buying a used Hong Nor X2-CRT Nitro Truggy, 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 Hong Nor website, or purchased separately on eBay. With an instruction manual, any problems with your model Truggy you may discover can easily be fixed.

Dampers
   When you receive your used Hong Nor Truggy, 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 Hong Nor 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 Hong Nor X2-CRT 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 X2-CRT 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 X2-CRT Truggy 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 Truggy 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 Truggy 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 Truggy 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 Truggy 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 X2-CRT 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 Hong Nor X2-CRT 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 Hong Nor Truggy 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 X2-CRT model and good racing.

Hints and Tips

Ackerman

   So What is Ackerman?

   If you place your car on a table facing away from you and turn the steering to full lock to the left, you will notice the angle the left hand wheel has turned is more than that of the right hand wheel. That is the Ackerman effect.

   Moving your car to the edge of the table, with the wheels still on full lock, push it round a complete circle. What you will notice, is the diameter of the circle made by the inside wheel, is smaller than that of the outside wheel. This is a good thing.

   Consider what would happen if both wheels turned to the same angle. In this example, the inside wheel would have a tendency to drag sideways, making the car unstable and difficult to drive.

   The standard kit setting on the majority of RC Model cars, are generally pretty good for beginners, but when your experience increases, you will find out just what tuning your Ackerman can do for your driving style and why it can be helpful when setting up your car for any particular track.

   Some of the cheaper RC Models have fixed position steering links. Others have various methods to change Ackerman settings, like changing shims under the ball connector etc. These days, most modern cars allow you to adjust your Ackerman by lengthening or shortening the links by simply removing two screws and repositioning the links in relation to the front suspension arms.

   Lengthening the links, by adjusting the pivot points of the steering arms back towards the centre line of the rear axle, will give you Less Ackerman, providing you with more aggressive steering as you enter a corner. Useful on slippery tracks, to counter when the car tends to slide to the outside of the corner as you first turn into it.

   Shortening the links, by adjusting the pivot points of the steering arms more forward of the centre line of the rear axle, will give you More Ackerman, making cornering less aggressive, more predictable and improving car stability, better for high grip tracks, with smooth sweeping corners.

   How to implement these adjustments varies from model to model so you will have to refer to your manual for full instructions.

Hints and Tips

Getting into RC

   When I first got into racing RC, all I had was a three year old clapped out Tamiya Boomerang, a silver can stock motor, three step mechanical speed controller, two 1400Mah stick batteries and basic Acoms stick transmitter.

   I was the newbie and most of the guys I was racing against had all the latest models, modified motors, matched batteries and top spec radio equipment, but I was still beating them easily. Why? The answer is simple: Practice. I had been driving that old car around my back yard and in the local park for almost three years. The others bought their cars only a few weeks or months earlier and had pestered their parents for the latest and most expensive car, motor etc, but did not have the experience to be able to control it. While I was steadily trundling around the track, they were crashing out on every other corner, popping ball joints, breaking wishbones and generally causing havoc.

   The moral of this story is all too obvious and anyone starting up in RC who wants to race please take note. You don't need the best equipment to win races. You can start with a cheap basic kit and with a lot of practice in some wide open spaces where you will not cause any damage, learn how to control your car. Remember don't try to run before you can walk. Stick with that silver can motor for a while and upgrade to something a little faster only when you have mastered the old one. You don't even have to buy new. If you go down to your local RC Club, there are always cars for sale. They may be battered and bruised, but if you get an old brushed silver can motor, a cheap 5A ESC, a couple of Nicad, or Nimh batteries, charger and simple radio gear, that is all you need to start practising and after a while, winning races.
