Tamiya Ligier JS9 Matra - #58010 (Radio Controlled Model Review)

1/10 Scale Electric Formula One Car - F1 Chassis:

  Released by Tamiya on November 30, 1978, this RC model, based on the alloy plate F1 chassis, is of the Ligier JS9 Matra, that was proudly introduced by Ligier in the same year at the Monaco Grand Prix. This new innovative F1 car displayed an extended rear wings with wide side pontoons. The front of the car had a sloping pointed nose, all of which improved the aerodynamics of the model.

  Although classed as a 1:10 scale car, the model was based on a 1:12 pan chassis incorporating a floating radio deck and a cast metal motor pod for the under powered RS-380S motor.

  The sleek lines of the Ligier JS9 Matra ABS hard plastic body shell model has made it a favourite with Tamiya collectors and is much sought after for the display cabinet.

General Information and Advice

   For those starting in Radio Controlled Racing, here are a few Hints and Tips: Firstly, buy a Kit not an RTR. That way, if something breaks you will have some idea how to fix it.

   Radio Controlled Model Cars are very fragile and easily broken. The main parts to protect are the Front Wishbones, Suspension Shock Towers, Dampers, Hub Carriers, Kingpins, Uprights and Toe in Blocks, so make sure you have a good strong front bumper and Lexan or Hard Plastic Body Shell and if available for your model, a protective under tray, to prevent grit and dust getting into any moving parts.

   The Steering Servo is also a weakness in high speed crash situations, so get yourself some good strong Servo Mount and Servo Saver. Also I would recommend Titanium Shafts, Turnbuckles, Tie Rods and pivot/steering shafts and if available for your model, lightweight Titanium Drive shafts, dog bones and CVD (Constant Velocity Drives). The standard steel types are far too easily bent.

   Gearing is another problem area on RC model cars. Head on collisions can easily break off gear teeth on Nylon/Plastic Spur Gears and even Bevel Gears inside the Gearbox. Heavy impacts can also loosen nuts and self taping screws that hold the Motor in Position, allowing the Pinion Gear to pull out of mesh slightly and rip the tops of the teeth on your Spur Gear. To avoid this to some degree, fit locking nuts and a new motor mount from time to time, so the self taping screws that hold the motor in position have less chance to come loose.

   Ball joints always cause problems. For top level Radio Controlled model 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 breaking free could easily end your race, so better safe than sorry.

   Many New car kits come with Nylon and Sintered Brass Ring type bearings. My advice is to discard these before initial installation and buy a good Hop-up set of Shielded Steel Ball Bearings. Or if you are serious about your racing, Teflon or Ceramic Bearings.

   One final piece of advice about the Setup of your Car. Keep the Centre of Gravity as low as possible. Ride Height is all important. For On Road Drift/Touring cars the Ride Height should be no more than 5mm, for Buggys, Trucks, Truggys and Monster Trucks, as low as possible depending on the track conditions. If Body Roll is a problem, handling can be improved with the use of Stabilizers, Anti roll or Sway Bars, stiffer Tuning Springs and, or thicker Silicon Oil in the Dampers. Also find somewhere to mount the Transponder as low in the Chassis as possible.

Gear Differentials


   The Gear Differentials, commonly used in Tamiya Buggys, Trucks, Touring Cars, Monster Trucks and some of the early Tamiya Formula One and Le-Mans cars, are by design more robust than the high maintenance Ball Differentials.

   The configuration uses a main drive gear, fixed on each side of the drive axles and either three or four small metal orbital bevel gears, in a plastic gear housing, providing the drive to each side of the car when cornering, to allow the inside wheel to rotate slower than the outside wheel.

   Maintaining your Gear differentials is crucial if your car is to be competitive. Regular greasing is required, preferably molybdenum grease with graphite flakes, smeared over the gear teeth. If neglected, the gear teeth grind and wear at a rapid rate and will quickly fail, leaving you with a potentially expensive rebuild.

   For slower moving models such as Monster Trucks, Rock Crawlers and budget end Off road Buggys, Trucks and On Road Drift and Touring Cars, where low friction differential action is not essential, Gear Differentials are ideal, providing drive to each wheel as required. However, for top level competitive racing ,On and Off Road, Ball Differentials are preferable. Admittedly, they require a little more maintenance, but the benefits on the track far outweigh the negatives of the old Gear diffs.

Hints and Tips

Servo Information

   Servos are found on all kinds of Radio Controlled Models. RC Touring Cars, Buggys, Trucks, Truggys, Monster Trucks, Rock Crawlers, Airplanes, Helicopters, Boats and Ships for Steering, Throttle Control, Rudder Operation and Wing Flaps.

   For complete RC beginners, choosing the right servo can be confusing, so here are a few tips to point you in the right direction.

   The standard, plastic bushed (bearings) type servos are fine to start with but come with plastic/nylon gears that can break easily in collisions. So, to protect your servo gears to some degree, make sure you have a good "servo saver".

   Servo Savers come in a number of forms and are often included as standard on some RC Models. The best ones, in my opinion, are those that use a small spring to absorb the shock of the crash and are simply fitted in place of the servo horn.

   For lightweight, small scale models, plastic geared servos are fine. But for medium to large scale RC models, I would recommend metal or titanium gear servos. These servos are by nature heavier and more costly than the plastic geared ones but are well worth the extra expense, for obvious reasons.

   Digitally controlled Servos use a microprocessor based controller board. They are generally faster, provide better torque and centralise more accurately than the older Analogue types, but again at a higher cost.

   As you advance in experience and skill, you might feel the need for something to match your lightning reflexes. Mos-FET, or simply FET Servos use Ball bearings and will provide the high speed response you crave, but at a price. However, if your budget will stretch to the higher cost, the improvement in performance can make a big difference.
