How does it compare to the xcelorin?

It has more punch than the Xceleron, even though the timing on the esc is set at zero.

Hi Evertonal

The internal cooling fan is a very lightweight aluminium part that attaches to the rotor by 2 grub screws. It is designed to reduce the internal temps of the lower solder ring for high stress applications like 10.5 touring car racing. In testing we found a 10-15 degree internal temp reduction in using the fan. The external motor can had very similar temperatures with or without the fan.

A simple way of reducing the motor temp is put a bigger rotor in. This will lose ultimate RPM but give you more torque (better feel) and run cooler with more natural brake effect from a stronger magnet.

Motor and ESC settings are very important. We set the motor on 7 degrees timing (minimum) from factory as this will be the safest setting to learn how your motor and ESC work together. Yes higher motor timing will create more power but it will also create more heat. We have found always increasing your ESC settings before your motor seems to result in a bigger performance step than simply cranking the motor up, that will just create excess waste heat in the motor.

We are working hard on the new ESC currently (for a year and a half now). We have taken national victories in Touring Car already with the prototype and have helped Craig Collinson (HULK on here) to get some career best results Off Road. We are looking to change the game with the ESC and so far all the indications are we are getting there very quickly :woot:

If you require anymore info please ask

Hi Ben,
Thanks for the response. I am quite tempted to try the internal cooling fan as I think it could help prolong the life of my motor. Does running the internal fan affect the performance of the motor in any way?

It doesn't make a noticeable difference due to the lightweight design. In the past on other motors I have run fans inside which have felt different in the power delivery.

We tested 12 different designs and we found the best compromise with the one we ended up with

Thanks again for the response. Where can I get the internal fans from? Ta.

We put them on today:

Are the fans available Ben?

Ben Cosgrove 03-06-2011 07:35 AM

Hi Guys

The optional rotors/sensor leads/fan are all available (althugh some are out of stock due to high demand)

Spares all available too.

Any good model shop that deals with HPI! :thumbsup:

I ran a 7.5 last time at the club and it wasnt far off the pace of my old lrp x12 6.5.

Its a fantastic motor and a bargain to boot ! Very pleased.:thumbsup:

Been trying very hard to get this motor going in my 17.5t boosted class but to no avail. Wouldn't even match the pace of my sp v3 that I had, any tips on setting this up? Will be used with a sp/hw esc. It just either gets too hot too quickly or is just outright slow in terms of laptimes. Everything was kept the same, (tires, goop, time of warming with goop) and my consistency is usually good so i don't think it was my getting lucky with the other motors and getting a better time.

Cheers.

Hi Defcone

Where do you race, any pictures or details?

What ESC setup are you running?

What gearing?

What timing?

What rotor?

What car and tyres?

Hopefully I may be able to suggest something to try based on the above...

I'm running 211 firmware hobbywing:
40 boost, 24 turbo, 250 Acc, 24 turbo slope, 4000start rpm, tried fdr from 4.8 to 6. Stock rotor(12.5mm) with internal fan, tried 7 to 17 degrees of can timing and didn't feel much speed difference so kept it at 7. But my fastest lap time was around 0.6 faster with the sp v3 motor and top 5/top 10 were 0.3 faster as well.

Running a yokomo bd5w, muchmore 32 absolute v tires with 17.5t boosted.

Thanks for the help, below is a pic of the track:

Really nice track!

Anyone running these with SP ESCs & what sort if timing are people setting on a 6.5?

evertonal 20-06-2011 07:52 PM

Flux motor with SP esc
 
I run my Flux 6.5 with an SP 2.0 pro esc. I started off with 0 timing as I melted an SP 3.0 6.5t motor a few months ago. That was far too slow, but I have run it a few times now and I am gradually working my way up the timing settings. I am now up to 11.25 on my esc timing and my motor is not running too hot. I think I could go up one more notch on my esc and I will be more than fast enough without melting my motor.

mikeyscott 20-06-2011 08:06 PM

What motor timing are you running, car and gearing?

evertonal 20-06-2011 08:16 PM

Flux motor with SP esc
 
Motor timing is as it came supplied, I assume that is zero but I don't know. I run it in a Yokomo B-Max with an 87 spur and 20 tooth pinion.

Whiskers 21-06-2011 02:46 PM

Is there any more news on the speedo?
