I just bought an 8ight 2.0e and it is incredible !!! I am having severe heat issues to where my esc is shutting down with the thermal overload protection. Could you please tell me what might be causing this issue ??? I am going to list everything I can that I have setup on the car so you can get a better idea. Thanks :-)
Stock Losi 8ight 2.0e.....14 tooth pinion, stock spur gear, mesh set perfect, stock diff fluid, I programmed the esc with the card and it has normal timing set, 8% drag brake, full throttle, 20% brake, Losi 14.8 v LIPO batt, Set the throttle curve on my M11 to ease up the snappy feel of the motor/esc, Losi Heat Sink installed, holes cut in body for airflow, air temperature was about 85 degrees, our track is kind of short so Im on and off the throttle quite a bit, the straight is about 80 feet long, ran for about 7 minutes before it thermaled.......any other info you need I can get.
Thanks for any help you can give me. My runtime seems to be fine but it has thermalled on me twice.
Make sure everything turns free with no pinion installed.
Drop to a 12 or 13 tooth pinion and make sure your gear mesh is loose (you do mention it is "perfect"), you should be able to run a piece of paper through the spur and pinion and not tear the paper.
Whats your motor,esc, battery temp?

So I need to go all the way down to a 12 tooth pinion ??? Everyone else is running 14 - 16 and having no heat issues. The drive train seems to be smooth.....seems free enough. I will have to compare it to something.
I dont have a heat temp gun but the esc turned off with the thermal overload protection. The car has nice speed and tons of bottom end with the 14 tooth. Are there any obvious things that could make the heat go up like this ???
do some research, the stock motor/esc combo on the RTR 8E 2.0 is CRAP, my suggestion, mabey get a CC/MMM 2200kv setup on 4s and have a blast
please dont take this the wrong way but i did alot of reserch on it, read all the reviews on amain EVERYONE has a problem with the stock elec.

my guess is that you need a 15 or 16 tooth pinion with 4s.
When I ran 4s with the 2100 kv motor, I ran a 16 nearly everywhere.
He is having heat issues with a 14T pinion and you tell him to go to a 15 or 16T one???
Aren't you the same guy that suggested to the other member to stay away from Electric because of their unreliability?
Maybe doing things like gearing up when already having a heat issue is what is causing more than 1/2 your ESC failures you speak of.

Absolutely correct. The Losi Bl systems are horrible. Sad because they make some amazing cars but they should have contracted out their powerplants with Tekin or someone else of a higher quality.
I would love to have a 8Ight-E 2.0

i had to drop my gearing down to 12/45t...and i'm running a 2050kv tekin r8 on a mamba monster. my temps with a 15t were hovering around 165*F and i know some run that hot...but i liked it better at the 145* it runs now lol

I stand by my opinion. I also run the SAME system he does and mine is the most reliable in my area ( everyone else has Tekin stuff.)
My car on 4s 5000mah Zippy with a 15 t pinon after a 15 min session comes off the track at 148-155 every time, speedo temp around 125 and batteries 106-110. My speedo failure I experienced is from the abuse of landing off a 9ft tall 28ft gap double, not due to my gearing choice. (it is the feature jump at our club track)
A 12 t pinion will compund your problem due to exceesive RPM.
I have had marginal luck with the LOSI speedo, but for these guys to call it JUNK is taking it a little far. I plan to purchase a MMv3 Mamba to have in the bag for a backup. But I am happy with the performance of the LOSI gear so far. I have only returned it 1 time vs the other guys here with other brands that have had their gear sent in for warranty 4 or more times in 5 months.

YOU CLEARLY HAVE NO IDEA WHAT YOU ARE TALKING ABOUT!!!!
Stand by your opinion fine but DON'T tell people to gear up when they are facing heat issues. It will only cause MORE heat, not less.
The motor spins at the same RPM regardless of the size of pinion but the smaller it is, the less it works, therefore creating less heat.
I may be new to this forum and it is not my intention to come in and be rude but you are making yourself look bad and while at it giving horrible advice that will only cause more problems for the person you are trying to "help."
Your opinions and experiences are definitely your own but you are the exception, not the rule. 999 out of 1000 people (who actually know what they are talking about) will agree Tekin/Castle are FAR better in every way then the Losi systems.

Honestly, do you like arguing that much?
I have been Racing R/c since 1987, you don't know me at all, so stop trying to determine how much I know about r/c. If what I am suggesting didn't work, I wouldn't waste my time typing it.
I have the system he is asking about, there are two of us running Excelroin Systems in my area, both us is run 16 /45 in our cars and both of us are temping in the same 140-155 range. How can you tell me that I am wrong?
Do you understand that gearing a bushless motor up to a certain point makes it more efficient, and having too little of a load on the motor is just as bad as having too much load on the motor?
If you re- read my post I stated at the bottom I was going to purchase a MMM for a backup as it is my opinion at this time that the MMM is the most reliable speedo out there. Last weekend alone I saw one TEKIN on fire and two others stop working. ( one of them is a team driver too) If that is your version of better then ??? I am confused.
You really need to relax NEU before you have an anuerism.

+1 gear down!! i run a 1850kv neu on 4s which is slower than your combo and our tight track has lots of turns with about a 90-100ft staight and i'm geared 48/14=3.42:1 ratio your spinning the motor faster and running45/14=3.21:1 even faster ratio and on what sounds to be a shorter track. Most of the people on here that are running 45/15 or 16 are on tracks like revelation raceway, etc. BIGGER tracks which need faster gearing. I'm with you nue racer!

Wish I could but I dont have a temp gun. I am getting one this week. Let me ask this, are temp issues common in all Brushless 1/8 scale buggies ?? It sounds like most of you are getting close to having heat issues as well. What are your experiences ?? And thank you for the help guys....even though there is some arguing going on , the info is pretty helpful.
