1/12 Scale Electric On-Road Car:

AYK RX3000 Super Expert - Radio Controlled Model



History and Info:

  Introduced by AYK Aoyagi Metals Co circa 1980, the 2WD RX3000 Super Expert chassis was available with two bodyshell options: Moon Craft Special (MCS) and RX-L (AYK Special).

  Success soon followed, with the car winning the All Japan Championship in 1981 and again in 1982, using an EXL 480 conversion.

  The model is based on an FRP double deck chassis, with lightweight aluminum screws and servo mount, turnbuckle track-rods, GX1200 differential, alloy motor-mount and ball bearings. A standard wound wire rheostat type speed controller was also provided in the kit.

  To race the AYK RX3000 Super Expert, it requires a high level of tuning for improved stability when cornering, to keep it on the track and give you more grip under acceleration. Even the smallest change in your cars settings can make a Big difference. Our simple to follow instruction chart will show how to attain the best Set-up for your personal requirements.

Buying a Used Radio Controlled Model
(General Information and Advice)


   There are essentially three reasons you might want to buy a used RC model; 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 car. 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 manufacturers website, or purchased separately on eBay. With an instruction manual, any problems with your model you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
   When you receive your used model, inspect 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.

   If your model comes 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

   A broken, ripped or damaged bodyshell, can be easily repaired with rubber solution glue (I use Shoe Goo). Also, for added protection and if available for your 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, some cheap steel drive-shafts wear and bend far too easily.

   If you intend to race your model at a competitive level, for strength and weight reduction, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

Examine the Drive System

   On gear driven models, open the gearbox 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, for racing 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.

   Drive Belt driven models need them checking at regular intervals for wear, tension and damage. If considered necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than approximately 5mm. Also examine the drive pulleys for wear. The pulley teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting.

Pinions and Spur Gears

Spur Gears
   Gears are a weakness on all 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 or 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 problem, if possible, fit bolts with locking nuts to the 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 racing, all 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 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.

Don't Forget those Bearings

Ball Bearings
   If your used model comes with plastic or 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 by the previous owner with bushings installed, you may have to change all the axles and drive-shafts. For more information, take a look at my article, How to get the best from your Bearings.

   Finally, good luck with your RC model and good racing.

How to put on 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.

Hints, Tips and Information

Your First Race Meeting

   When you finally find a racing club near to where you live, that initial experience of stepping up onto the rostrum and looking down over the track can be very daunting. But soon, as the race starts, adrenaline will kick in and away you go. For the next five minutes, your focus is on nothing but getting your car around each corner, avoiding all the other cars on the track and just getting to the end of the race.

   Maybe your batteries dumped or you crashed and the car was damaged, perhaps you didn't actually come last, whatever happened, it doesn't really matter - you are well and truly hooked.
