Tamiya Can Am Lola - #58021 (Radio Controlled Model)

1/12 Scale Electric Racing Car - RM Mk.1 Chassis:

  Released by Tamiya on July 1, 1980, the inspiration for this car came from the Canadian-American (Can-Am) Group 7 racing cars of the mid 70s. The model was that of a Formula 1 car and was a new innovation for Tamiya RC models.

  The new upgraded RS-540SD Black motor was seriously quick and the Can Am Lola body shell was of a lighter Lexan polycarbonate, which allowed the car to travel even faster. The chassis was fully adjustable, came with a bevel gear differential and was fully ball raced.

  The mechanical speed controller contained a micro-switch for braking and acceleration was smooth and gradual. This vastly improved the response and handling of the car.

  Unlike most Tamiya models the Can Am Lola was considered an ugly car compared to those that had gone before. As a vintage car they are now rare and very collectable, but the cars off-putting appearance make this one of the cheaper "First 100" models.

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.

Hints and Tips

Tires for RC Models

Rubber Tires:

   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, as to what inserts they use. Even the top level racers rely on a bit of local knowledge on tracks they have never raced before.

1/   Once you have decided what inserts to use, position them inside the Tires ready to go onto the rims.

2/   You will need strong fingers to pull and maneuver the Tires over the rims, so you may need the help of an adult. I would recommend NOT using metal Tire levers or a spoon as they can not only damage the fragile plastic rims but can also put small tears in the rubber, that could cause problems later.
   The technique I recommend, is to first of all hook the Tire on one side of the rim, then using the thumb and forefinger, grip the Tire and pull it upwards and over into position around the middle of the wheel, then over to its final position on the far side so that the beading is seated in the spigot. then position the near side beading in the opposite spigot making sure the sponge (or rubber) insert is not trapped and positioned centrally.

3/   You have the option of either gluing or not gluing your tires in position. If the track you race at is not too grippy you can get away with it, but on high grip tracks there is the possibility the tire might pull away from the rim and ruin your race.
My recommendation is to glue them.
   Superglue is the thing to use. To do this, carefully pull the beading out of its seating, put on a spot of glue, then quickly push it back down. repeat this at least 6 times around each side of the wheel.
Superglue can be dangerous, so this is best done by an adult.

Hints and Tips


Electric Motors for RC Models

Winds and Turns

Q/  What does 15x2 or 17x3 mean?
A/  The first number relates to the number of times the wires are wound round each of the 3 armature segments, the second number relates to the number of wires side by side. So a 15x2 would have 2 wires laid side by side and wrapped around each segment 15 times.

Q/  What is the difference in performance between a Low Turn motor (eg 11x1) and a High Turn motor (eg 27x1)?
A/  A Motor with Less Turns like an 11x1 means high current draw from the batteries which corresponds to less runtime, but More Power (Torque or Punch) Best for tracks with lots of corners and short straights where fast acceleration is needed. (use a small pinion)
Motors with More Turns like a 27x1 give you More runtime, but Less Power. So you get a smoother response and are therefore easier to drive. Better for less experienced drivers and Long straight, sweeping corner tracks. (with a large pinion) This is correct for Brushed, Modified and Stock Motors as well as Brushless Motors.

Q/  How do the number of winds effect a motor?
A/  A Motor with More Winds (number of wires eg 13x5) is less demanding on the battery and smoother in acceleration. Best for low grip, slippery tracks.
A Low Wind Motor (eg 11x1) is more punchy and can be difficult to handle. Best on high grip, hot weather Tarmac, or indoor carpet, high acceleration, low speed tracks.

Advance and Retard

Q/  What is Advance and Retard?
A/  On the Endbell of a Modified Motor (where the brushes fit) you will find two screws that hold the Endbell to the Can. If these screws are slackened off slightly the Endbell can then be twisted either Clockwise (Advance) or Anticlockwise (Retard). On Sensorless Brushless Motors this adjustment can generally be made in a similar way (although there are some Brushless Motors that have fixed timing for Spec level racing). Sensored Motors can be adjusted via the ESC.

Q/  What does "Advancing" the Endbell position do?
A/  Advancing the Endbell Reduces runtime, increases Punch (acceleration) and RPM to give a higher top speed.
On the down side, for Brushed Motors, the brushes wear faster and the increased current draw creates more arcing thus increased heat and Commutator (Comm) wear. Brushless Motors can lose some efficiency at the end of a race because of overheating due to increased current draw.

Q/  What does "Retarding" the Endbell position do?
A/  On both Brushed and Brushless Motors, Retarding the Endbell Increases runtime, decreases Punch (acceleration) and RPM to give a lower top speed and for Brushed Motors, brush wear and Commutator (Comm) wear is reduced.

Brushed Motor Basics

Q/  What is the effect of hard and soft Brushes?
A/  Basically, Hard brushes give a lower current draw, so consequently give longer run times and lower torque so less punch (acceleration)
Soft Brushes on the other hand increase current draw thus give higher torque and increased acceleration. Of course the down side of this is that Soft brushes wear much faster and must be changed more often. (I change mine when they get to around 5mm)

Q/  How does changing the brush spring change the motor?
A/  If you fit Stiffer Brush Springs your motor will have More power at low revs and also a lower top speed. I only ever fit stiff springs on bumpy tracks to reduce brush bounce.
Weaker springs reduce power but increase RPM so give less acceleration but a higher top speed. Good for long, sweeping, smooth tracks, where you can carry good speed through the corners.
