Tamiya Wild Willy, Willy's M38 - 58035 (Radio Controlled Model Review)

1/10 Scale Electric RC Military Jeep - WW-V1/WW-V2 Chassis ★

  Released by Tamiya on November 27, 1982, the Wild Willy, Willy's M38 was based on the world famous US army Jeep.

  The durable chassis uses nylon and ABS resin injection mouldings provides a strong construction.

  I found the build of this model to be awkward for some reason. The manual was well laid out and easy to follow but some of the parts needed some patience to put together.

  A gear differential, sealed gear box with coil spring friction suspension, two part wheels with large sand tires go some way to make the car just what it is to drive - fun all the way.

  Wheelies are easy to induce with the 2WD Wild Willy, just squirt the trigger and away you go - brilliant.

  As one of the "Tamiya First 100" the Wild Willy M38 is often purchased to build and display, but there are a number of used models out there in reasonable condition at bargain prices.

Buying a Used Tamiya Wild Willy, Willy's M38
Military Jeep (and What to look for)


   There are essentially three reasons you might want to buy a used Tamiya Wild Willy, Willy's M38 Electric Military Jeep; 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 website, or purchased separately on eBay. With an instruction manual, any problems with your model Military Jeep you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
   When you receive your used Tamiya Military Jeep, 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 Tamiya Wild Willy, Willy's M38 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 Wild Willy, Willy's M38 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 Wild Willy, Willy's M38 Military Jeep 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

   On Belt driven models, the Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The 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.

   For Gear driven models, the gearbox of your used Military Jeep 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 Military Jeep 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

Spur Gears
   Gears are a weakness on all Military Jeep 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 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 possibility, fit bolts with locking nuts to the Electric Motor 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 Electric Military Jeep 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 Wild Willy, Willy's M38 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 Tamiya Wild Willy, Willy's M38 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

Ball Bearings
   If your used Tamiya Military Jeep 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 Wild Willy, Willy's M38 model and good racing.

Hints, Tips and Information

My First National

   When I first started in RC, way back in the late 1980s, I would turn up to the weekly club meeting, with my Tamiya Boomerang, Acoms transmitter, two sets of crystals, a couple of 7.2v batteries, a charger and a tool box with a wheel spanner and a few spares.
   It was three five minute qualifying rounds and a final, and every month we would have a trophy meeting. The trophies were donated by a two of the older semi professional guys who basically ran the club and over the years had collected what must have been hundreds of trophies and had no space for them anymore. The lure of a trophy always brought out the "not as enthusiastic types" and the small church function room was always packed on those nights.
   About a year in, my collection of B final trophies was beginning to clutter my room, and my dad bought me the new Tamiya Manta Ray. That was the big turning point in my RC career.
   From then on it was A finals all the way. Then one day in the summer of 1992 the club organisers (the semi pro guys) asked me if I would like to go to a BIG national meeting way down south in Malvern. I asked my dad and with a bit of prompting he said "why not".
   When we got to that meeting we found there were around a hundred competitors, with ten groups of ten. I was in group "H". a two of my friends went down with us and they were in group "I" so were on just before me.

Hints, Tips and Information

Gear Differentials

   The Gear Differentials, commonly used in 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.
