again, read the manual...

Motor Temperature Cut Off:
Parameters from 160 Degrees to 260 Degrees (10 degrees incremental).
Motor temperature cut activation is indicated by blinking “F” and “R” LEDs.
ESC Temperature Cut Off:
Parameters from 160 Degrees to 260 Degrees (10 degrees incremental).
ESC temperature cut activation is indicated by blinking “F” and “R” LEDs with
solid “N” LED

woah, hold on. You're running boost? Now we know why you are so hot. Set that thing to race mode blinky and start from scratch.

Holly boost batman....

I run it race blindly but the other day switched it to race open to see if it had any timing from the factory. I have never changed it. The slew was set at 8 from new. Should I take it down to zero?

I dont think it matters what the slew rate is, as long as your timing degrees are at 0, the slew rate and start/finish RPM can be anything you want, if theres 0 degrees of timing it wont do anything.

Check and make sure your timing is at 0 for accel boost and top end timing.
Or just go back to blinky mode, thats what I run my 4x4 and 8th scale at.

The Castle fans are just fans only, the case is plastic and doesnt really dissipate heat very well.
A heatsink/fan combo will give you better temps because of the dual effect.

I use one from 3Racing that I found at a hobby shop last year, it works great. I've tried the Castle ones and they usually fail pretty quickly.

thank you

Wanted to follow up on my 1/8th scale eb48 VTX8,

Just got a reply from Nick saying they found the problem and its on way back.
This is a great American company and thank you Viper and Nick.

The SCT 410 is still running great and should have the EB48 running within the week. Good news
Will be running a cap from now on in the eb48.

you should put it back on race blinky and not touch race open ever again on a 4 pole setup LOL.


But seriously, those motors do NOT like any ESC timing / boost in them at all. They have all they will ever need built into them.

Good to know in case anyone else asks!

Is there a reason you don't want to use that Integy one? I mean the fans are replaceable, it comes in different colors, it works well.

One caveat for the Integy one is that when you get it, it's a little oversized. Take a screw driver and just curl it closed slightly around the screw driver. You don't have to go far at all. The screwdriver is just so you don't bend it and put a crease in it.

You'll get the idea when you see it. It literally took me about 15 seconds to do so don't let it deter you.

I've never persoanlly tried the Integy ones, I just lucked out and found the 3Racing one at Superior Hobbies one day and put it in and its been flawless with approximately a year of use on it.
I've always heard Integy stuff was questionable to start with, but if there was a black Integy heatsink/fan hanging on the wall, instead of the 3Racing, thats probably what I would have bought that day. I just needed a heatsink that day and I didnt have any preference.

Me personally, i did find some usage of time on a 4 pole 540 to be beneficial, but this was:

- Tekin Pro4 4000kv motor in an SC10 4x4
- Against 4600kv + motors
- Timing at like 5 degrees only at a higher RPM start range
- dropping pinion size 2 teeth

I did this as I had no top end in comparison to the 4600kv motors at the track and trying to go with a bigger pinion got things hot. Using this method, I dropped my temps and got the top end I needed.

But in general I agree the motors are probably better off without any timing.

Cain has it right on!!!!!

You can add a little boost to make up a small difference (this case 4000 to 4600). I wouldn't boost 4600, for most its already too much.

Slew rate does make a huge difference - its how fast the timing is added when the RPM numbers are hit. Too high just wastes the energy and creates heat. 2-3 is probably most ever needed. If you do use it.

kaisertrip - that's what we are hear to do...

One thing to remember about fans - best place to attach them is right to the positive and negative lead of the battery on the speed control. This way they have the least effect on the BEC in the circuit. Some systems want them placed in the receiver. This can help cause issues during voltage spikes.

3Racing has 1.8 scale fan?

Good stuff there. I didn't know they stressed out the BEC.
