Ok, crash course in electrics...
in no particular order.


#1 throw away the 4AA battery box, it is not needed at all.


#2 might as well throw out the switch too, more trouble than its worth


#3 purple wire is the Antenna, put that in the antenna tube. (Does not need connection to anything - It picks up radio waves.) You must have bought a 29Mhz band radio!!



#4 in the MSC's bag there should be 1pg instructions? Read it twice. Shows you where & how you mount the MSC on the chassis.


#5 plug in the 2 servos to the receiver - Steering should be channel 1. Put 8AAs into the TX.


#6 MSC should have a little red plug, this plug is same as on the 4AA battery box and/or switch. Just plug the MSC's red plug straight into the receiver "batt" socket.


#7 do you have a charged 7.2V pack? If so plug it into the MSC... and your radiogear should come alive straightaway. Turn on your TX and wiggle all the controls until you're fully satisfied.


#8 Set both sticks' "TRIM" (the adjustment levers) to 'centre/middle' before you attach anything to the servos.


#9 Now that you have centre'd the servos, you can screw on the servo arms that Tamiya has provided. Use the right one for 'Futaba' - different brands, different sizes.


#10 screw the servos into the car as per instructions. Connect up the steering & MSC as instructed.


#11 Test the steering... if it doesn't do left/right same as the stick, flick the "servo reverse" switch.


#12 Test the MSC, convention is that 'forwards' (= transmitter stick push Up) is when the little MSC finger slides *away* from where the wires come out of the board. You may have to fiddle with the linkage to adjust how far it turns *each* way, it must go only as far as the last metal contact - it must not go too far until it falls off, or too little that it doesn't reach 3rd speed. Do this for both fwd & reverse.


#13 ok now connect the motor wires. Yellow to yellow, grn to grn.


Car should now be operational!!






It is good practice to always turn the Transmitter ON first, before turning on the car. If you turn on the car first, you will have no control without the Transmitter on.


If you see someone else also playing a RC car nearby, it is IMPORTANT that you walk over to him/her and say "Hi, what frequency are you using?". Read the frequency on your Crystal eg 29.905Mhz etc. If he is using the *same* exact frequency as you, DO NOT turn your Transmitter on AT ALL. You will clash with his car and jam his signal - that is BAD!!! Do not turn On your car until he is finished and has turned his transmitter Off.








ok, about that switch.


Note... although youare given the Futaba's switch, that goes inline between the MSC's little red plug and the receiver.


However I think it is more trouble than its worth as it *only* turns your radio Off... and the switch can get dirty & damaged & its dead weight.


And it ONLY turns your radio Off. It DOES NOT STOP YOUR MOTOR FROM RUNNING, if your battery is connected up - you get me?


If you are not running your car, you should never leave your battery hooked up. Always unplug it otherwise your car will runaway or could cause a fire.


Get rid of your switch and your car will be instantly ON when you plug in the battery.That way you'll never ever forget to unplug the battery when not running.

now the steering servo...the holes to connect to the steering bars are too small for the screws


and also look at the side of the car with the motor...ok to make it more clear...hold the chassis...right hand at the rear and left hand at the front :p ...the motor is on the right side...


to the left of the motor are 2 lines sticking out and under is an oval stand with 2 holes for part C18 which is a fin...what does that do?

You mean the 3x14mm Step Screw into the part B10 ?


Or the 2 bars called C6 ?


No the holes should fit - exactly 3mm. Hope you're using the right screws.


Self tapping screws will be very tight to put in first time as they 'cut' their threads into the plastic then. You can make it a little easier if you get a candle and rub a little bit of wax onto the screw thread before you put it in.





Futaba S3003 servos need the slightly smaller screw (2.6mm) at the middle.

Ahh, that little plastic fin is amazing an Tamiya innovation! It will improve your under-car aerodynamics by 135% and, in the event of Saddam Hussein lobbing a Scud missile at your city, it will sacrifice itself to shield your valuable motor from nuclear exposure.


Errr.... No.
Maybe not.





Short answer: C18 does Sweet F. A.



Long answer: Its dead weight - Remove it and throw it as far as you can. Use a little sellotape to cover up the 2 holes for the screws (stop dirt getting in). Congratulations - you have gained yourself 2 extra spare screws!!!

"Body Posts" ??



You can snip them shorter if you want to, no harm there. If you snip them too short for your next shell don't worry, they are only a few buxx to buy a new set.


If you don't snip them sometimes they can break if you do a violent rollover. Haha my car travelled at least 50m on its *roof* today (flipped at ultra highspeed), roadrash'd a fair chunk out of all 4 posts.
