On the data log, how many streams are you recording?

When you move the throttle "what" is gone?

I'm wondering what gearing I should have on my rc8b with rx8 and 1900kv 4s and 6s just looking for a happy medium in heat I don't mind getting a fan or it not getting hot until towards the end of the charge

15 or 16 pinion on the 1900 kv motor 4s only is not intended for 6s most likely burn or demagnetized the 1900 motor , if you want to run 6s run a lower kv motor like a 1400 or 1300 kv

Will it be as crazy fast as it is now on the 6s and should I run that pinion size with a 46 or 50t spur? Cause on the 4s it still gets really hot im running a 44t spur 19t pinion tried going down on pinion still over heats had the 50 spur and waaay too slow

44 spur 16 pinion is what i`m running on an outdoor track , and the temps on my buggy are 160 to 170 on a 85 to 90 degrees day , plenty fast for me , I was told by Tekin rep you can run up to 180 degrees , but that`s pushing it if you ask me , 50 spur is more for a truggy , 44 , 45 , 46 spur is fine on the buggy , 19 pinion is way to big for the 1900 KV motor , a friend at my local track ran 18 pinion and 44 spur on a Techno buggy and he fried his 1900 motor it was at 220 degrees when it seized literally smoking hot , needless to say he sent in for replacement , are you a racer or a basher ? sounds like you want to go fast you need to go a lower KV like a 1400 , 1500 KV motor with 6s and gear accordingly , ( always check your temps ) fast is only good on a straight away , but not so much on the turns if you running on a track .

Im confused, I plugged up 2 new RX8's to my hotwire and there was a 254 firmware. I updated both of them.

When I go to the Tekin website it says the latest is 250......

Im building it for the track and bashing. With a lower kv motor will I see 60+ with low temps?

yes I'm running on a large outdoor track and I want to FLYY down the straights my buggy is pretty good through the turns already Im running an airtronics 94910 and I'm good with throttle control and 100% delay set on esc for power. I just wanna smoke the nitro

Guys, a question..

I finally got some my tekin rx8 2200kv'd savage flux xl set up on 6s, and the ESC took a poop - two terminals melted off, as did one of the wires

The setup was purchased used, the previous solders were pretty bad and broke off after I moved it around. I resoldered everything properly, 12ga wires for power, 14ga to the motor, proper mesh and all. Batteries were 3s 50c 5200mah brand new. Outside temps were maybe ~90, it was on a baseball field, and the thing fried about 10 minutes in. Obviously, everything was very hot.

Batteries were slightly warm, voltage was good and balanced on all cells. I am lucky nothing shorted and burned the whole truck down

I have another tekin that gets worked hard and no issue, but I am just curious what could have caused this, so I know if I did something wrong

IMHO To much voltage , Amps , 6s on a 2200 kv motor , might of been to much for the ESC although it can handle 6s but the kv of the motor needed to be in the 1350 to 1500 kv for 6s range , 4s would have been the ticket for the 2200 kv motor , also what size pinion are you running ? setting up the gearing is also important so you can keep heat down on the esc and motor . you should call Tekin and described your scenario they might be able to help .

Thanks, I will. It had an 18 tooth tooth pinion which I believe is the stock flux size.

Fluxes are advertised as 6s ready with the stock mamba setups, so I thought the Tekin should handle it no problem. Too bad, I've been putting this thing together for 6 months probably, and it burned out 10 minutes into my run

Spoke with Tekin, they recommended a 1550kv motor on 6s, so it seems I have three choices - go to 4s, drop down to a lower kv motor, or pick up a different esc..

oh well, so much for my 10 minutes of fun

hey guys, I know that the Gen2 puts out 210a per phase.

Any idea as to what the Gen 1 (red heat sink) puts out amp wise?

Thanks.

mavdriver

iTrader: (9)

I believe is 200 but i wouldn't do no more than 180 amps always give yourself some head room never push the limits of any ESC that's how they burn up , also buy your self a temp gun if you don't have one .

I just switched from nitro and im running e buggy with an RX8 gen 2 and 1900 motor combo and a few guys from my track told me the stock gauge wire that comes with it can cause a problem with too much amps going through the small wires and deans can also cause the fires? what gauge wire and what plugs are safe?
