Tamiya did a pretty neat thing with the rear axle of the RM01. The stub axles on each side of the rear axle are held on with 3 screws, the circle of the three screws is exactly the same as industry standard 12th scale wheels. Simply remove the stub axle on each side and re-use the three screws to mount your standard wheels. The offset of Jaco wheels is perfect, CRC and BSR type wheels makes the rear wider.

Black front yellow rear is very common for stock 12th scale on carpet but double check what works for other racers at your local track.

Gearing may be different depending on the diameter of your new tires. If your new jacos are smaller than your used RM01 tires you will need a larger pinion to keep the roll out the same.

Paul has fitted a Xenon front end on the RM01 and its really flying (thanks to Dave.. There is more details on our blog here in what must be the most exhaustive review ever for a 1/12th

I've gone and bought a RM01 myself now

im working on changing the diff/spur
i have pick up 1/8 aps ceramic dif balls but not sure what grease to use
the only grease i have is aw grease tamiya ...or white auto grease is that all right to use?
i did use masking tape with 1/4 bearing and cut off extra and kimberg 78 spur
i have a 13.5 binky so for me im thinking a 41 spur or would that be too low (for a newbie)?
thanks

It is disappointing to read the mods required just to fit small diameter tires to the RM. I don't understand why Tamiya wouldn't design the car to be more accommodating...

Stock front end requires filing down (or replacement) and after reading the blog, the rear also requires some filing...

True, but the Tamiya is designed to be more scale in appearance with the Prototype bodies by Tamiya

Fred Medel drove an RM-01X in 12th Stock at iic this year with a total of 2 sets of Jaco Black/Yellow tires, no issues, and that is on the stickiest track conditions one could ever encounter

I trued them to 45.5mm Rr, 43.5mm Fr
The car works great, is smooth and easy to drive with all kit parts on those tires, frankly I was stunned by the performance level that car achieved in conditions that had a lot of cars flipping over

I personally like the RM01 over the 12R5.2, cause of the simplicity of the car and especially the front suspension.
To bad you can't use the tires as long as on the other 1/12 cars, that's why i bought the 12R5.2 to be able to use the tires much longer.
But i would switch back imediately if i could solve the tire problem.

Did you modify the front suspension yet like in Paul's post below? Or his blog he also modified the rear suspension to fit smaller diameter tires to battle grip roll...

Modded the steering blocks by taking 1.5mm off the underside so I can run smaller tyres. I now have to dremel the same amount off the top of the kingpin though as it rubs the inside of the Jaco wheels. That's a job for tomorrow.

Also, found the chassis drilled to take a small servo, so my futaba 9650 has gone in.

All in all, a very nice build. Centre shock and alloy 'big bore' damper tube were both very nice bits of kit. Fitted 80t 64dp spur after reaming the centre out to 10mm. Used a 6x10 bearing and its a perfect fit. Shouldn't wear out like the tape mod when using higher powered motors. Only let down is the body posts which won't tighten down.

Now have to wait 2 weeks before I can hit the track. See how it measures up to my Rev7.

I haven't done any modifications yet, perhaps it may not be possible as i have the regular RM-01 but full-option and not the RM-01X version.

Tron,

Get the car, it is blast to drive and is sneaky fast. You wouldn't think it but it competes with the other raced out 12th scales. Panda TQed and won with his at TQ last weekend.

I have an RM01x that is still in the shrink wrap. I'm willing to barter it for a CRC 1/10th scale car (LE, SE, Gen X10) with the slider rear pod. Anyone wanna do some trading?

Even though I've modded the rear end to take smaller tyres, I didn't need to run small tyres at the weekend to be competitive. Ran 43mm fronts and 45mm rears all weekend until the final on the Sunday. It was then 41.5 and 43.5.

I placed 6th in 13.5 on Saturday, after qualifying 6th. I missed out on practice after a mistake first time onto the straight with full power left the car in 2 pieces! Only breakage was the centre pivot plastic. It did leave me on the back foot all day though. Should have done better in the final but a silly mistake dropped me out of second and left me last half a lap behind the next car. So not a bad result considering.

Sunday I wasn't meant to be running the car, but my Rev8 had a terminal argument on the same corner as the Tamiya the day before. I didn't do a full qualifying run apart from Round 1 so ended up misplaced in the C final with Kevin Creaser fresh back from the IIC. So we just had some fun racing each other. Outright pace should have had the car near the back of the A though.

Yes, the car has mods, but the only expensive mod is the Xenon front. When I add up the cost so far, it's still cheaper than the majority of 1/12 cars in the UK! And the Xenon front is rapidly becoming a must have for Associated drivers over here.

RM01X is on the way. Now that I have ordered one, I'm sure Mrs. Tamiya will discontinue it.
