Hi Guys,

I have been testing the ESC alot here in the UK with the Beta Software and have found some interesting results.

I did a run against a GM powered car on a 30metre indoor track. I was using Firmware 228? This is where Id like to know what others are using? I have tried 231 but it seems you get no advance or boosting at all until 100% full throttle.

Here are my settings for 228

12: - 6
13:- 4
14:- 1
15:- 3

I have found 228 very very smooth and you get a nice mid range boost and then a supercharge at full throttle about halfway down the main straight.

I was geared at 8.3 with a 10.5. Temperatures were borderline and also there was fading, very similar to the feel of 5 cell.

What firmware are all you guys using?

Cheers

Stef

Have you guys try setting the radio (on throttle) @ 95% when calibrate the speedo...then after that, boost it back up to 100% or 105% range...?

I ran out of options to try so I will try to do that.............

For those who also run TEKIN, you guys know why ppl need to do that...FADING.

If I let it cool down it would be fine for about a lap and then the same thing would happen.

Eventually it failed altogether.

Sounds like the sensor in the motor is going bad or already bad....sp is generally in sensorless mode once the speedo can tell the motor is starting to unload

what settings do you have on the esc?
I have had opverheating hassles in mod when running around 20 - 22 mm rollout and found i was actually undergeared which caused the motor to overheat as it was peaking to max rpm to early.

I've had what I believe to be the same sensor problem. Cleaned out the motor and sensor board which initally solved the problem but after less than 30 seconds it was back again. (this was a SP V3 13.5)

Tried an old Novak SS and that seems to work fine so far.

Going to ask a friend to try my SP motor at the weekend to see if it is the motor/sensor board/sensor lead.

However, I find it a little strange that suddenly a number of people are encountering the problem after running the new software, seems like a bit more than just coincidence?

set the timing to #3 for FDR on a medium track start around a 9.75 with the motor set a zero degrees. I ran the 2.0 with the SP 3.5 geared at a 9.25 with no issues.

I think you will find its nothing to do with sensors, it will be one of your 3 windings that has started to fail. Theres three main reasons motors fail that I have seen:

1 Windings are starting to melt and short together when hot
2 Rotor failure
3 bearings

Next thing you will find is that one of the power wires comes unsoldered due to the excess heat from the winding. It will be at that point the motor fails altogether.

Regards
Mike

sensors do fail mate!

I had to change my 2 day old sensor board after the motor slowed down. After I put a another sensor board on, it was up to speed.

but regardless, the version 3 motors are a piece of *^%&$^%(

Well not to battle anyones personal experience with the v3 motors but I just finished a 7 month off road series where I ran a 10.5 v3 motor and had zero issues with it. I abused it, over heated it and it still ran great. Haven't had a issue with it at all. I have 3 different winds of the motor and all of them have been good. They are not in a touring car, but a 4 wheeler. But they have been smooth, powerful and dependable. I have seen every motor manufactures motor fail and usually there is a different root cause if you continue to dump motors. Just my 2 cents.

I'm sure that sensors do fail but I have yet to see one fail. And I can tell you so far I've had 100% good luck with the V3 motors. Not a single problem with them so far.

For me its been Novak, Orion 2008, and a friends LRP x12 that I have seen fail.
