Tamiya Subaru XV - #58567 (Radio Controlled Model Review)

1/10 Scale Electric Touring Car - TT-02 Chassis:

  Released by Tamiya on July 3, 2013, this TT-02 chassis based self assembly RC Model, is of the Subaru XV released in 2012 with raised suspension of an Impreza for off road racing.

  The Lexan body shell in this kit is a realistic representation of the sleek lines of the original. An ESC and motor are provided but needs battery, charger, paint and Radio equipment to complete.

  The TT-02 Chassis was produced by Tamiya as an entry level model, to replace the aging TT-01 Chassis, that has been around since 2003. The TT-02 design is capable of utilising modern day rechargeable batteries, is also durable and easy to build and maintain.

  The shaft driven Chassis configuration, employs front and rear orbital bevel gear differentials, fully independent double wishbone suspension with coil spring over friction dampers.

  A 540 brushed silver can electric motor and an Electronic Speed Controller (ESC) are included in the kit. Radio Equipment, Battery, Charger and paint for the body shell must be purchased separately.

  Like the majority of Tamiya budget kits, this one comes with Plastic and sintered brass Bush type bearings, that when dust and grit get into them, abrade the drive shafts that spin in them, making them sloppy and causing dog-bone problems. I recommend these should be replaced, by a full set of Shielded Ball Bearings, on initial assembly or as soon as possible.

  To get the best from the TT-02 Chassis, it needs to be fine tuned so it has enough grip to hug the corners at high speed, without slipping off the track and accelerate smoothly under control. Small adjustments can make a Big difference and our simple to understand, step by step procedure, will guide you to the best Set-up for your driving style.

Buying a Used Tamiya Subaru XV
Touring Car (and What to look for)


   Buying a used Tamiya Subaru XV Electric Touring Car, or any used RC Model, has a number of advantages. It is generally cheaper than new, ready built and may come with a variety of expensive hop-ups already installed. Cheap, pre-loved bargains are always becoming available. However, depending on the age of your purchase, it may need a little tender loving care before you can take it out on the back yard.

   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 Touring Car you may discover, can easily be fixed.

Dampers
   When you receive your used Tamiya Touring Car, 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.

   If the body shell of your Tamiya Subaru XV 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 Subaru XV model, fit an under guard to stop dirt and gravel entering the chassis.

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 Subaru XV Touring Car model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   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 Touring Car 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 Touring Car 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.

Spur Gears
   Gears are a weakness on all Touring Car 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.

   Ball joints always cause problems. For top level Electric Touring 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 popping off, could easily end your race, so better safe than sorry.

Servo Gears
   The Subaru XV 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.

   If body roll on your Tamiya Subaru XV 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.

Ball Bearings
   If your used Tamiya Touring Car 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 Subaru XV model and good racing.

General Information and Advice

   RC is one of those sports that can be simply bashing around the back yard, or taken to the extreme of National and International Racing: For those who would like to enter this world of miniature Models, here are a few basic Hints: Firstly, buy a Kit not an RTR. Then, if something does break on your model, the experience you gain by building the kit will give you some idea how to fix it.

   Radio Controlled Model Cars are easily broken. Wishbones, Suspension Shock Towers, Dampers etc are prone to damage, so make sure you have a good strong front bumper and never run your car without its Body Shell in place.

   The Steering Servo is also a weakness, so if your kit does not have one, get yourself a good quality Servo Saver. I would also recommend you replace the soft steel Turnbuckles, Tie Rods and pivot/steering shafts with Titanium versions and if you get serious about your racing, lightweight Titanium Drive shafts, dog bones and CVD (Constant Velocity Drives). The standard steel ones bend far too easily.

   Gears in RC model cars often cause problems. Head on collision accidents can damage gear teeth on Nylon/Plastic Spur Gears and sometimes even the Bevel Gears inside the Gearbox. Hard impacts may also slacken the nuts and self taping screws that fix the Motor in Position, making it possible for the Pinion Gear to pull out of mesh a little and damage the teeth on your Spur Gear. To try and prevent this, you should always fit locking (Nyloc) nuts and if your mount uses self tapping screws, change the plastic motor mount occasionally to ensure a tight fit.

   Plastic Ball Connectors can cause problems. For top level Radio Controlled model car racing, they need to be checked for tightness and if considered necessary changed after every race meeting. Something like a loose fitting connector popping off could easily lose you the race, so always err on the side of caution.

   Quite a number of New car kits come with Plastic and Sintered Brass Ring type bearings. These can cause problems if at some time in the future you want to fit a full set of ball bearings so I recommend you discard the brass and plastic types before installation and get yourself a Hop-up set of Shielded Steel Ball Bearings.

   Finally, try to keep the Centre of Gravity of your model as low as you can. This can vastly improve the handling of your car when cornering at high speed. For On Road Drift/Touring cars the Ride Height should be around 5mm, for Buggys, Trucks, Truggys and Monster Trucks, as low as practical for the track conditions. Body Roll can be reduced by using Stabilizers, Anti roll or Sway Bars. Tuning Springs may also help with thicker, or thicker Silicon Oil in the Shock Absorbers. Also look towards mounting the Transponder as low as you can in the Chassis.

Electric Motors for RC Models

Brushless Motor Basics

   Choosing the right Brushless motor for your needs can be a daunting task for those new to Radio Controlled Models. If you have a local club perhaps you could ask some of the more experienced members for their advice, but a little basic knowledge about the subject, so you know what questions to ask is always useful.

   All Brushless motors are rated by Kilovolts (KV) and is an indication of the revs per minute (RPM) that particular Motor can attain running freely, under no load conditions, per Volt of input.

   For Example: To calculate the Maximum RPM of a Motor listed at 4000 KV, connected to a 7.4 Volt Battery, simply multiply the two: 4000 x 7.4 = 29600 RPM.

   The two main types of Brushless Motors used in RC are Sensored and a Sensorless Motors.
   Sensored Motors can be connected directly using s cable, to the Electronic Speed Controller (ESC). The ESC is then able to monitor the performance of the Motor and regulate Current output, to attain smooth, controlled acceleration. Advance and Retard timing is made automatically by the ERSC to change torque when exiting corners and give you more RPM for long straights.

   Sensorless Motors can only be set manually for Advance and Retard timing and once that setting is made you have to stick with it. For obvious reasons, Sensorless motors are cheaper to buy than the Sensored type: Ideal if you just want to bash around in the back yard, but not so much if you are serious about your racing.

   Brushless Motors, need a reasonable amount of maintenance if they are to remain competitive. For top level racing I recommend you strip, clean and re-oil the bearings every 2 or 3 meetings (Check out our "get the best from your bearings" section).
   Gearing your motor correctly for any given track is always important. (Check out my Gearing tips on the Pinions Section of this site) A cool motor is an efficient motor. As your motor heats up towards the end of a race, it will loose efficiency. Gearing correctly can avoid this problem to some degree and simply following my simple guidelines, described in the aforementioned article can help you not only keep your motor running efficiently, but help you stay in front of your opposition.

   One last tip .. When re-building your Brushless Motor, to safely replace the Rotor, use a rolled up piece of paper and place it into the Can. This will protect your rotor against damage. Then carefully remove the paper before replacing the endbell.
