Generally speaking, a smaller rotor improves driveability (smoother) and gives more topend but the downside is slighly lower efficiency and less torque. Temperature isn’t much different.

unfortunately no comparison possible between powerprofiles of SPX StockSpec and boost profiles SXX StockSpec is possible!
The reason is that algorithm works differently and SXX StockSpec clearly makes more power.

Lowering the timing on the motor (e.g. changing from insert “oo” to “ooo” or “oooo”) will of course lower the motor temperature, but you sacrifise power in higher rpm range slightly and may need to alter gearing to reach enough topspeed again.

kV rating is not affected too much by sensor timing, therefore we don’t give different ratings for different timings. So you can go with 7100kV for 5.0t at -10° (oooo insert) as well.

standard in all X12 motors is 12.5mm rotor, Tamiya specially requested a 12.0mm rotor in their new motors but ourselves we stick to 12.5mm as we feel this is the best allrounder!

4.0t with LiPo is VERY fast and not the wind I’d recommend to use with LiPo’s… common winds for LiPo use in a touring car is 4.5 to 5.5, 5.0t seems like the best compromise and is what I’d recommend.

Also on brushless motors it is important to oil the bearings from time to time, wrong gearing or wrong adjustments (timing or speedo) may also cause excessive heating which can result in bearing failure.

I assume you run TC, correct? If so, I’d start with profile 5 and lowest motor timing (e.g. “oooo” insert) and then increase from there and check motor temperatures (they should be below 90°C). (LRPSXX TC Spec)

Marc is currently testing quite a bit, so he switches back and forth between Tamiya (LRP SphereTC OEM version) and SP speedos. I’ actually not sure what he used at the last race but I know that Jilles won with our speed-control…

paralleling capacitors is/was only required if the capacitor was of bad quality, with a good quality (single) capacitor it’s not required and therefore not worth the hassle to add another one

We have tested with many different capacitors and so far our original type, which is a very expensive LowESR version “Made in Japan”, worked best. None of the other (bigger & smaller) we tried worked better. So in my opinion there is no point in trying other capacitors.
Especially stay away from the flat “SuperCapacitors” as they don’t work well.

As for the gearing at the Worlds with the X12’s:
- we ran 4.5t
- lowest timing setting (oooo), which seems to work best anywhere!
- gearing ~8.6:1
- powerprofile 3 on the speedo

Remember this was with 6 cells.

As for the temperatures, anything below 100°C is fine!
The X12’s does get fairly warm on the outside as it makes a lot of power and also transfers the heat well from the inside to the outside due to the clamped stack. But we have a magnet with a very high temperature grade, so until no solder starts melting there is no danger.

Guide to electric r/c motors.

You can check for the rpm, current draw and KV. Here is a video of a Novak 4.5T brushless motor being tested. Amazing to see these motors turn 67,000 rpms.

Here are the technical specs from Team Powers.

XRAY T3 Radio Control Car

A totally new car where the balancing point and geometry have been changed and designed for lipo and brushless motors. Designed to make the car easier to drive and faster.

R/C Car Video

Technical  Specs:

• Need only 20grams to perfectly balance the r/c car.
• Motor is moved 4mm more to the center.
• New bulkheads, arms independently mounted.
• Bigger angle steering position.
• More inside roll center position.
• 1 piece tuneable topdeck.
• New lipo holders.

Feedback from the XRAY team drivers:

• More traction, good feeling.
• Made for lipo, good weight balance even with lower weight limit.
• Better steering.
• Different flex characteristics.
• More mechanical traction, more speed thru the corners.

Overall looks like a great new r/c car from Team XRAY. Visit the rc cars for sale section of this website where you can buy from popular online r/c hobby shops.

Tamiya Brushless ESC 01  (TBLE-01) specifications:
Forward / brake / reverse * maximum continuous current = 100amps * input voltage = 6.6 – 7.2v * 30 x 42 x 31mm * weight = 80gm * overhead / overload / low voltage protection system * compatible with Tamiya TBLM motor series.

Will do a test these coming weeks and give you a full report soon.

Tamiya 12T Brushless Motor

I installed it in a Tamiya M05 mini. It is a nice motor, faster than a Sport Tuned but maybe slightly less powerful than a 13.5T brushless. After around 8 minutes of running, the motor is still very cool to touch.

Tamiya Brushless 12T Motor

Here are some details from the manual:

Tamiya Brushless Motor ( TBLM-01 12T):
Sensorless * 3,160KV (or 3,160rpm/volt) * length = 54mm * diameter = 36mm * weight = 182gm * item 54132 * use exclusively with Tamiya Brushless ESC 01.

Gearing:
Touring car = 6.8 – 8.0
Buggy = 9.0 – 11.0

Lipo Batteries Guide

Charging

1. Only use a Lipo charger. Do not use other types.
2. Typically charge at 3 amps. Follow the charging guideline that comes with your battery pack.
3. Do not connect the positive and negative together. This will short and permanently damage the battery.
4. Do not remove the battery from its case.

Using

1. Do not let the voltage drop below 6 volts.
2. Once you notice your car dropping in power, immediately stop using the battery.
3. Do not discharge the battery after use.

Storing

1. Store battery at 50% to 100% charge in a safe environment.
2. If not using for long period of time, maybe better to store at only 80% charge.
3. Store between temperatures of -20c and 35c.

Final tip is to read the instructions that come with your pack. Different packs have slightly different ways of charging rate and storing.

Faqs:

1. How many times can you use a Lipo battery in a day? I have used my Lipo pack as much as 5 times during a racing afternoon with no drop in power. Just let the battery cool down before recharging.
2. How many charge cycles can a Lipo have? I have read that some will last 1,000 charge cycles. I have packs that are 2 years old and are still going strong.
3. What are C ratings? In general, a higher C rating should mean more power. All things equal, a 5000mAh 40c pack should be better than a 5000mAh 30c pack.

Hope this helps.

Lipo battery – Review of the Orion 3600/28c versus the Hi Energy 5000/30c. I am surprised that I sometimes get faster race laptimes with the Orion. Maybe because it is lighter by 70 grams.

For example, a 1/36 Losi Micro T, complete with battery, charger, and radio control system, sells for approximately $80.

For 1/10 scale on road, one of the cheapest is the Tamiya TT01 expert built (XB) sereies. These come already assembled. Only thing you need to buy is the 7.2v battery pack, charger and 8aa batteries for the transmitter. Sells for approximately $ 250.

For HPI, look for their E10 RTR models (approx $160) and their HPI RTR Sprint 2 Sport Toureza (approx $179).

Here is the list of the cheapest ready to run (RTR) top 20 electric powered rc cars. Please note these are estimated selling price and might vary from different hobby shops.

Hope this helps you make a buying decision. You can buy these r/c cars online, visit the RC Cars For Sale section of this website for a list of online hobby shops.

Have fun!
