I don't usually use any special settings with the MR03, but I do with F1...
Dual Rate
- 85% (the F1 has too much steering as it is)
Throttle Punch
- Forward: 50%
- Reverse: 30% (to help with that damn reverse delay)
No other curves or anything
Total weight of the F1 was ~210 grams the last time I checked... so not light be any means. No weight reduction has been done besides aero bits falling off the body from crashes

Stock motor break-in tips
21-Nov-2011
1) back in the 1/10 days, we used to break-in new motors by submerging them into water until the water turned from clear to black. I used to use an old water bottle but in have (use the bottom half). Fill it with enough water so that the motor can be submerged. Hook up the motor to a power source (so the motor is working) and then submerge it (still running) into the water. What this does is break in the brushes,i.e. brushes will now contact the comm(commutator) fully, yielding more power.
For mini-Z, I'm recommending no more than 45 seconds, regardless of the colour of the water. Any longer than that and you'll have no brushes left (they will be worn too much). You'll find you have no power on the track.
Remove the motor from the water and let it dry completely. Lube the bushing/bearing with some quality oil (I use either Reflex Racing or Atomic lube), install and run it.
2) Use a break-in stand. I use the PN one. To use, connect the slave motor to a power source (should be between 1.5V to 2V) and run for 45 mins.
From PN's site directly:
When properly broken in, a motor can achieve a 10% to 20% increase in power over a motor that has not been broken in.
The PN Racing Motor Break in kit includes the motor stand, a slave motor, and pinion gears.
Using a slave motor allows the motor to break in without running under its own power (which heats everything up and glazes the bushings, preventing a quick break in). Properly seating the bushings will increase performance by reducing drag. If you run the motor under its own power to break it in, you risk heating and glazing the bushing surface where the armature pole makes contact. A glazed surface will be harder to wear in. When running the motor under its own power arching occurs that may pit the brushes and communicator before the communicator can be properly worn in by the brushes. Using a slave motor will drastically reduce the amount of arching. Note that the only way to remove arching completely on the new motor would be to remove one brush and break each brush in individually.
Most experts agree that a motor should be broken in at 1.5 to 3 volts for 10 mins or more. This can be achieved by connecting to the Much-More Motor Maser, using the motor break in feature of the ICE charger, or simply connecting the slave motor to a single 1.2 AAA cell for 1.5 volts or 2 AAA’s in serial for 3 volts.
Please note that it is important to keep the lead wires separate on the slave motor as well as the break in motor during operation.

Futuba 3PK and R246 KO Mini-Z Module Adapter
21-Nov-2011
The adapter fits perfectly-no slop where it fits into the radio
Tip for those using the 2.4Ghz Mini-Z module in their 3PK. You have to ensure the radio is in PPM mode, otherwise the combo will not work (default mode for the 3PK is PCM mode). Also, you have to adjust the values within the radio so as not to damage your car (i.e. steering travel limit). Instructions are included with the adapter kit.

Using MR03 board in a F1 chassis
02-Oct-2011
Many of us at the track have built our F1s from scratch since the only F1 chassis available from Kyosho are the AM band versions.
You too can build your F1 from scratch or upgrade the board to a MR03 board by following the steps below:
1) The coreless servo motor needs removed- I replaced with an older AWD cored motor
2) Wiring changes:
a)Make sure to swap the positive and negative wires where they hook unto the board for the steering motor.
b)Swap the green and orange wires on the board for the steering pot. Otherwise, the steering won't work right
3) On/off switch needs replaced- I replaced with one from an old i-series board.

dNaNo base setup for RealTracks
22-Sep-2011
For our RealTracks testing, we found that box stock cars needed a front tire upgrade to Kyosho 40 degrees and the cars worked like magic on the track. We have tested the following cars: Mazda 787B, Porsche 962C, Ferrari FXX, Nissan 350Z GT500 2007. The only exception to the front tire upgrade has been the Aston Martin DBR9 which needs a different setup- further testing is required for this one car.
Kyosho Hard front springs
Kyosho Soft t-plate
Atomic Disc damper kit- Black spring bottom, silver spring top, Kyosho shock oil (comes with Mini-Z oil shock)
PN Racing alloy wheels (Nissan uses 19F and 19R)
PN Racing 8 degree rear tires
PN Racing 35 degree front tires
Kyosho Bearing set
Kyosho Adjustable Ball Diff- uses 1 spacer- Also switched to optionl 34 Tooth Diff Gear
Kyosho Alloy Front Suspension Kit
Kyosho Alloy Rear Hub Kit
Stock Kyosho motor with 7 Tooth Pinion and as noted above optional 34 Tooth Diff Gear

Tiki Tiki (Chase Mode) Board Explained
22-Sep-2011
Chase mode (also known as Tiki Tiki mode in Asia) functions to limit power output to 70% of full throttle. When the moment comes to attack, a push of the 3rd channel button on the transmitter increases power output to 100% for 3-second burst of speed. This enables greater driving control and also adds the excitement of overtaking duels so drivers can enjoy nose to tail racing battles. Also, the number of power boosts can be set to apply a handicapping system to level the playing field for drivers of different experience levels. At the time of shipment, the overtake function is set to a maximum of 5 times per race.
How to activate the Chase mode
At the time of shipment, the MR-03 with Chase mode is set with its standard 100% power output setting. The Chase mode is activated simply by pressing and holding down the pairing button.
How does the Chase mode Handicap System Work?
The number of 3-second Chase mode speed bursts of 100% power output that can be used is able to be limited for each race. Depending on the driver$B!G(Js skill level, the number of Chase mode speed bursts can be set higher or lower, and therefore apply a handicapping system for the race. Drivers of any skill or confidence level can compete effectively and enjoy racing with this handicap system.
(Requires optional No.82080/I.C.S. USB adapter and PC to change handicap settings).
Number of speed bursts for each Handicap Classes
Chase mode Legend- 1 times
Chase mode Champ- 3 times
No Handicap- 5 times
Handicap +1- 6 times
Handicap +2- 7 times
Handicap +3- 8 times
Handicap +4- 9 times
Handicap +5- 10 times
Handicap +6- 15 times
Handicap +MAX- 250 times
The number of speed bursts in Chase mode is counted from when the chassis power is switched on until it is switched off. Each time the chassis power is switched on, the number of speed bursts enabled is reset allowing the handicap to be applied at the start of each race.
