Tamiya Toyota Land Cruiser 40 - 58405 (Radio Controlled Model Review)

1/10 Scale Electric Rock Crawler - CR-01 Chassis:


  Released by Tamiya on April 23, 2008, the Toyota Land Cruiser 40 was the first Tamiya model based on the 4WD CR-01 Rock Crawler Chassis.

  The ladder framed CR-01 chassis, employs two metal side bars, jointed by a number of fixed and pivoted ties and struts to allow it to twist and flex. Two bevel gear type differentials enclosed in tough plastic axle housings are employed with a third orbital gear differential mounted in the centrally positioned gearbox with the 540 motor. Two universal drive prop shafts link the axle drives to provide excellent controlled handling.

  The suspension uses four oil filled dampers set at 45 degrees and four coil springs separately mounted behind each wheel.

  Four huge 125mm tires are perfect to traverse all types of rough and rocky terrain with ease. In my opinion this is one of the best Tamiya Radio Controlled model designs to date.

Buying a Used Tamiya Rock Crawler (and What to look for)


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

Make a General Visual Inspection

Dampers
   When you receive your used Tamiya model, 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 Tamiya 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 Rock Crawler 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 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.

Examine the Drive System

   The gearbox of your used Rock Crawler should be opened up to check for damaged gears and wear. If there is excessive backlash in the gearing, these should be replaced. A thin coat of grease on the gears is enough to allow smooth operation and reduce further wear.

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 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 possibility, fit bolts with locking nuts to the motor mount and remember to check them for security after every two or three runs.

Steering Servo and Servo-Saver

Servo Gears
   The steering servo is also prone to damage, 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 Tamiya Rock Crawler 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.

Hints, Tips and Information

For Those New to RC


   For those starting in Radio Controlled Racing, I have prepared a number of articles with some useful Hints, Tips and Advice, based on my many years of experience in the sport.

   The categories include Battery information, Motor advice, ESC history, Servo choice, Setting your gears, Ball joints, plus many more.

   Entering the world of RC Racing can be a scary, so there are also articles relating to my own personal experience on entering the sport, and how, with determination and practice, you can progress to the higher levels of competition.

Hints, Tips and Information

Rubber Tires for RC Models

   Rubber Tires ALWAYS should have either soft sponge or rubber inserts. They will not function as they should without them. And if you are totally serious about your racing they should be glued to the rims.

   You should also have at least three different compounds (Soft, Medium and Hard) for varying track temperatures in On Road tarmac racing Touring cars and varying pin sizes for carpet and Off Road racing Buggys and Trucks.

How to Mount Rubber Tires onto Wheels/Rims.

   Before mounting your Tires, I would recommend talking to the more experienced racers at your local club, concerning what inserts they use. Even the top level racers rely on a bit of local knowledge on tracks they have never raced before.
