I have tried gearing from 5.1 to 6.7..... I am not using drag or push, I have had timing boost vary from 45-55 ( by advice, others all use MAX). I am mad slow down back straight, Once I thought I had it right, the car was crazy fast for @ 8 laps then crazy slow, off at 198f. That time at 6.1 max timing. Please help, I have had nothing but problems and melted motors trying to get situated since 203. I want to keep up with the others on the straight, most have tekins, a couple MMP, SP ect. It has been fine in infield through all FDRs. I know I am doing something wrong, and before you ask I have a EVO V and TRF416, both super smooth drivetrains, no binding... THANKS SORRY SO LONG
overheating problems within 8laps suggests that you are overtimed. with the 40-50 degree boost you ought to have 0 timing on the motor. if you do have 0 on the motor, then perhaps boost rpm band is so low that it is giving too much timing at too low an rpm.

what rpm range are you using?

And a few people answered you last time, saying you're way off with the gear ratio.

Try like a 4.6 final drive, and start with 5-20k RPM range, with like 40 timing in the ESC, and 12* on the endbell. See how it goes and work the end RPM down and timing up from there.

Sorry, motor is stock (not touched)tekin redline. I have used 5k-15k range and 3k-11k range both results were too hot. I have people telling me gear higher, & people saying gear lower, I am hoping someone has a similar class or settings. I know that at least 4 tekin users are MAX timing @6.0 and way lower temps which I dont understand, but I temped thier motors with my snap-on infared gun and got 140f ish, Iam @198f w same settings.

Today I run Tekin Hot Wire within Windows XP 32-bit, running within the free VMware Player ontop of my Lenovo S10 running Ubuntu Linux. I'm not the biggest fan of Windows OS... nor would I even think about bringing an expensive Mac laptop to the track. Inexpensive netbooks are great for the track (or really just about any time of personal computing)
VirtualBox is another popular choice, and entirely free.

I had GTB

I did get a couple replies last time, (then 208 started with many post) but at the time the lowest I could go was 4.9 with gearing that I had. That still was too hot (even w no turbo and @40 timing), I have since purchased many spurs and pinions so I can try anything. The FAST guy at my track was saying I was geared way too high (at 4.9 after driving my car) and told me I needed to be in the 6s range. I know everyone is trying to help, but its getting hard for me roasting motors, buying motors, and just wanting to hang on the straight. I am newer to the hobby ( @ 1 year now) and all this ESC boostin started @ when I did. I had GTB then outta no where it was Tekin Tekin Tekin. Like I said, no problems on the infield, just majorly slow on straight... Again Thanks for your opinions. I just want to figure it out.

AUDI 0000:

Not all motors are built the same. perhaps you should test out your motor in 'Dual' mode first and gear it with a recommended fdr. (ref: novak suggests fdr~3.75 for a Novak 21.5R motor)

Dont worry about the speed first, just temp the motor after 2 mins to see if it falls within normal temp. Dual mode should produce less heat than sensored mode.

If the temp is still too high, then maybe its your motor.


Another question is, what spur size and pinion size are you using to achieve your FDR? A larger spur + larger pinion combo would be easier to the motor compared to a smaller spur + smaller pinion combo (assuming the same ratio). This is just the way physics works on pulley systems.

check your gear meshing make sure it has some 'play' between spur & pinion.


Last question is: what type of batteries are u using? how many mAh and 'c' rating?

I hope this helps.

Ok, so this evening I was getting my car setup. Made a few quick throttle snap across my floor and snap! Blew up a rotor. Now my RS doesn't turn on. It powers my RX, but not the ESC.

I'm guessing it shorted out in the motor then the ESC? Sounds like it is going to have to get sent in.

Default Drifting Tekin RS Pro Esc 4.5t gets super duper ultra hot!!!????

saap yaal!

so heres my set up, questions regarding my rs pro redline system......

****my esc gets super hot still--is it because i am using a bigger than normal drifting tires n rims?

ive dropped down my pinion from 29t all the way down to 25t today and switched back to 26mm t-drifts rims n tires away from LP's hopefully thats the main reason why my esc rs pro gets super duper hot after 10 minute run time of carpet drifting

any advice would b appreciated folks!
i switched from novak to tekin this year -- but this is my only problem i am encountering for drifting----- should i drop pinion down more? for example 19t 64p/ 106t 64p?

generally is using bigger than standard wheels n rims for drifitn causes my 4.5t rspro to overheat? or i just needs to drop my pinion down super low??
tnx folks!!

I already got the iPhone.
I also have an MBP, but I would rather leave it at home - it is a little bit to expensive to bring to the track.

Sure, if I had the money, I could buy a cheap-ass netbook. But I still go to school (university) and live on the little money I get from the government, so I can't just buy another laptop.
Even if I could, I won't pay twice as much (speedo + laptop) as LRP or HobbyWing.

Laptops aren't that much money you don't need a expencive fast laptop.

I have a old ibm laptop thats kind small I got it for free on Craigs list because the battery is done. has a 400mhz processor and 128mb of ram running windows xp. and works great for the Hotwire and thats all i use it for. Hot wie doesn't take much to run. These laptops are cheap to buy if not free in the $50 and less range.

I prefer using Ubuntu, but it doesn't do everything I need it to do, so I occasionally have to boot into windows for work, to play games or to adjust my ESC. OSX is no different. It doesn't do everything and likely never will.
A Mac is a proper computer, it will last 5+ years easily, while most plastic windows crap computers won't even last 2 years.
I would compare a mac to a Xray and a pc to a Tamiya TT-01.

I use parallels on my MBP, works great.
I rather take my MBP to the track then waste money on a crappy netbook.

RC racing is just a hobby not a sport. About as physical as it gets, is fueling up a 1/8th buggy. All kidding aside does anybody know the best netbook for the money? I really dont like computers so cheaper the better.
