Tamiya McLaren MP4/6 - # 47010 (Radio Controlled Model Review)

1/14 Scale Electric F1:

  Released by Tamiya on May 12, 1992, the 2WD TamTech McLaren MP4/6 (#47010) came as a complete assembly kit, with a TamTech 202 R/C Radio Unit, C.P.R Unit P-05DB and an RK-370 electric motor. A 7.2v NiCad battery and charger are required to complete. The model is the perfect entry level car for those new to RC.

  The model is based on a sturdy monocoque type chassis, with three point suspension, precision differential gearing, slick racing tires and a highly detailed injection molded bodyshell and wing.

  This model comes with bush type bearings, that after a short while, when dust and grit get into them, can actually wear into the metal drive shafts that spin in them - our recommendation is that these should be replaced by a full set of steel shielded ball bearings ASAP.

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.

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, transmitter, two sets of crystals, a couple of 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.
   I remember that first race like it was yesterday. It was a staggered start and I was away next to last. I had never raced on a proper outdoor dirt track before. My only experience was on indoor carpet, but my old Manta Ray took off like a bullet. Most of the others in my heat were rookies and by the end of the third lap I was up with the leader. He was good very good but I stuck to him like glue. Each twist, turn and jump brought me closer and closer, this guy was fast, but I was faster for a while anyway. A lap before the end my old over worked 1400mah battery, was struggling to give me what I needed to keep up with him and my buggy got slower and slower. I ended up third in that first race, but wasn't about to give up that easy.
   There was a shop at the meeting and straight after the race I nagged my dad to get me a new battery. In those days money was tight and normally before dad would spend anything he would consult my mum, but this time she wasn't there and after watching my performance in that race he didn't need much pushing to get me that badly needed new battery.
   Waiting for the second round seemed to take an age, but when it arrived I was pumped up and ready with steely determination. I was away third after finishing third in the first round, so my duel with the guy who beat me before carried on where it had left off. Two laps in and I was on his tail. He wasn't going to beat me this time. We lapped a couple of back markers and were quickly catching up to a third. He slipped past him in a flash, but when I moved in, the idiot drove straight into me, knocking my Manta Ray on its back. The marshal was oblivious to my plight. I shouted my head of but the marshals eyes were fixed on what I guess was the car of one of his friends in my race. The next thing I saw was my dad, bounding across the track like a gazelle, picking up my car, putting it on the track and giving me the thumbs up. I drove like the wind, passing car after car, slowly working back up to third, where I eventually finished.
   But it didn't end there. Because my dad had ran out onto the track, I was disqualified we pleaded our case and eventually were allowed to continue.
   The third round heat arrived. This time I wasn't going to let anything stop me. My focus was to win that race and beat that guy who had all the luck so far. Because of the previous race I set off last. Car after car was left in my wake, until once more it was me against him. Mano a mano, he saw it was me and he upped his game. Lap after lap we duelled for the lead. Coming into the very last lap I was a nose in front and pulling away. With each corner I could sense the battery was once again giving up and my car started to slow down. Corner after corner I could see him getting closer and closer. we got to the final straight and he was right on top of me breathing down my neck. I held my breath and jammed over the throttle leaver and just crossed the line before him I had won my first national heat race. and it wasn't to be the last.

Hints and Tips

Tires for RC Models

Sponge (Foam) Tires:

   Sponge Tires can be purchased either pre mounted, glued and trued on the rims, or separately. Fitting the Tires onto the rims can be messy, so here are a few tips to make it a bit easier.
   If you are fitting new Tires on old rims, make sure the old sponge Tire is completely removed. To do this, I recommend using a wood lathe and apiece of wood, at least 300mm long and more than the width of your wheels, with medium grit emery paper stuck to it ... sand paper will also work, but emery is harder wearing ... This will also be used for truing a wheel. (Described later)

How to Mount and Glue Sponge Tires onto Wheels/Rims.

1/   Mount the Tires on the rims. Make sure they are reasonably tight on the rims, too loose and you might have problems.

2/   I find this to be easier if either in the lathe, or on the car itself. (but be careful with that glue)
  Using your thumb and forefinger, lift up the Tire off the rim, then using a small spatula or a thin piece of rigid wood or plastic dipped in glue (I recommend Evo-Stik, Impact Adhesive) slip it in the gap, making sure both the Tire and the rim are smeared. Then lower the Tire back onto the rim and press it down. Turn the Tire approximately 60 degrees and repeat.

3/   Depending on the width of the Tire you may need to repeat the process on the inside also.


How to True Sponge Tires.

   Truing Sponge Tires is essential if you are serious about racing competitively. To do this you will need the piece of wood, as described earlier and a good pair of vernier or digital calipers.
   Sponge Tires will always wear unevenly, weather you race on Carpet or Tarmac. The outside wheels will always end a race smaller than the ones on the inside, so after each race I recommend swapping them over (unless you are fortunate to have a new set for each race) and dont forget to adjust the steering trim on your transmitter before the next race.

1/   Before starting, check each mounted Tire for diameter and order them smallest to largest. Start with the smallest and mount it in the lathe.

2/   Make sure you are wearing safety glasses before you start this procedure: Lay the sanding wood under the Tire so that it can be pivoted up from behind onto the Tire. Start the lathe spinning, so that as you stand infront of the Tire, it is rotating downwards. Slowly lift the sanding wood and try to hold it ridged as it comes up against the Tire. There will be a high point on the Tire that if you hold the bat rigid enough will eventually wear down until the Tire appears completely concentric. at this point stop the lathe and measure the diameter on the inside and outside of the width. If needs be, repeat the process until satisfied.
Repeat for each Tire, matching them in pairs for diameter.
If considered necessary also trim the sides.
