Bolink Eliminator 12 (Radio Controlled Model Review)


Navigation: Sitemap  ▶  Manufacturers  ▶  Bolink

History + Information (and How To Set-up Tips):


  Introduced by Bolink circa 1988, the 2WD Eliminator 12 pan car, was available as a basic FRP version with oilite bushings, or full graphite with ball bearings.

  The model design is based on a pan plate chassis, with front coil spring over kingpin suspension, rear coil spring over friction dampers, T-bar and alloy motor / axle mount.

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

Caster

   Caster is basically the angle the steering kingpins or steering pivot points, leans back in relation to the horizontal when viewed from the side of the chassis.

   To test the effectiveness of your cars caster, place your model on a flat surface, point the front wheels straight ahead and push the chassis over to one side to simulate body roll when cornering. You will notice that as the car leans over, all four wheels also lean over in the same direction. Tires provide the most grip when the wheels are perfectly vertical and the full width of each tire is flat on the ground. Body roll pushes the wheels past the vertical and reduces the amount of tire contact. Now, if you turn the front wheels as if cornering and again push the chassis over, you will see that in this position, the front wheels are now more vertical, giving you better ground contact and therefore improved grip.

   Another effect of caster can be seen by disconnecting your steering servo and pushing your car along the floor. Because of caster and the kingpins leaning back, your car will naturally roll straight ahead.

   Obviously, the more body roll your car induces, the more positive caster you need to counter it. Buggys, Trucks and Truggys, because of their high ride height and long dampers have more body roll and therefore require more positive caster than on road cars, with their low ride height and shorter dampers.

   If you consider a corner as having three parts: An entrance, middle and an exit. Caster influences each of them.

   With a high degree of positive caster, as you enter the corner and body roll is at its greatest, steering is better. In the middle section, as body roll reduces, steering is less effective and some under-steer is induced, that will continue as you accelerate on corner exit.

   With a low amount of caster, steering response is improved in the middle section of low speed turns and will be more likely to over-steer on corner exit because of increased front end grip from the tires.

   Too little caster can result in difficult handling on corners and poor stability on the straights.

   Most modern RC model kits come with a standard caster setting that has been set for the best handling by the manufacturers. If you are new to the sport I would recommend you stick with this setting until you get a little more experience.

   Methods to adjust caster can vary from model to model. Sometimes it is as simple as moving the position of a plastic washer from one side of the top wishbone pivot bar to the other, or simply using a small clip. Models from some manufacturers often have specific caster blocks to change the angle and had to be purchased separately.

Hints and Tips

Radio Frequencies

   After buying your first car, it won't be long before you need more than simply bashing around the back yard, or out on the street. So you will be looking around to find a club that is not too far away where you can do some serious racing.

   Before you can start racing, you will need at least three different sets of crystal frequencies. The race organisers will note down all your available frequencies when you register at the track and allocate one of those frequencies to you for your heat. To avoid change over problems from one heat to the next, they generally try to give you a frequency that no one in the heat before or after is using, but always check to make sure before you put your car down on the track and switch on.

   There is nothing more annoying than to be in the middle of your best qualifying race and some idiot switching on their transmitter in the pits, on your frequency. Not only could it spoil your race, but it could cost you a lot of money if at the time you are travelling at top speed along the straight, loose control and crash head on into the wall. Just imagine how you would feel.

   Now, imagine this scenario. You are at your RC meeting and you need to run your car to check out some changes you have made, either after a crash repair, to adjust the steering servo, or just fine tune your car before the next race. What do you do?

   Before you switch on anything, the first thing to do is check with race control, to make sure that none of the racers presently on the track or in the next heat are on the same frequency you want to use. The people in charge are always willing to help in these situations and if none of your three available frequencies are safe for you to use, they will often lend you some crystals, sometimes for a small fee.

   Some of the bigger meetings use a board displaying all the possible frequencies, indicating which of those frequencies are in use at that time and which are available for others to use. To claim a particular frequency you simply take a peg or marker off the board so that others wanting to check their car out can not use the same frequency as you. Before the next heat, this board is updated and any missing pegs must be accounted for. So obviously the best time to claim your frequency, is at the start of a heat and you must return it before the start of the next heat.

   So, be cautious, use the protocols at your track as they should be used and you won't make any enemies you know it makes sense.
