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:

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?

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...

Ben

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?

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.

What motor timing are you running, car and gearing?

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.

Is there any more news on the speedo?

Not having much luck with my 6.5 hpi, thermals regardless of what I do re gearing and ended up with zero timing On the SP esc with 83/22 on a sx3 :(

Suggestions

Not sure why thats happening mate.

I ran a 5.5 today on a grass track, in really hot conditions with no problems.

Have you checked to make sure your transmission is running free?

On the list for later tonight. Drop pinion off and give it all a clean and check. Feels free, but proper check

I ran one 2 day in the sx3 geared 24 pinion, as craig can confirm it was very hot 2day no problems wotever. Dont get me wrong it was v hot but excellent motor!

6.5 or 5.5 on an 83 spur?

I've tried 83/22/23/24

80/23/24

6.5 standard timing, kit spur so 83.

STD motor timing for me too.

Sorry for the next question, what esc?

Have just dropped pinion off and all free in the drive train.

Lrp sxx tc v1 no fan as well

Does that esc have timing options etc?

Dont think so mate, just run it standard, wot eva profile setting 3 is lol.

Ok many many thanks for the info :)

Dms regional on a tight indoor track next weekend

Mikey... two of us running 6.5's today

one on a SP equivalent V2.1 speedo and the other on a SXX v2 both with zero timing on the speedo and zero timing on the motor...

One had 21/84 FDR of 9.75 (v2.1)

Other had 22/80 FDR of 8.86 (sxx v2)

Mix of Astro and Grass at Oswestry track, Air Temp about 28c

Both motors were temping around 145c

Neither thermalled :thumbsup:

Not sure if that helps...

What pulleys are you running? so i can calc your FDR ?

2.58:1

9.39 Ok, but very hot
8.98 thermalled
9.74 thermalled
9.32 thremalled
8.61 thermalled
10.21 thermalled

Going to check over the ESC and motor during the week.

If I do the DMS regional I'll prob run a 7.5

Really? We have not chose the layout yet, and with a 30ish metre straight, it "wont" be tight.. ;)

Ok I was only going by comments to me from other racers. Either way 7.5

Tested again no timing on esc 83/24 shutdown.

Going to contact mb as reckon something faulty.

Got a big straight at torch.

Just so I'm not going mad.

The picture, can you confirm what the timing is? My thought is minimum.

Mikey

The pic shows the motor is fully wound back, this means that the motor is at its minimum which in the case of the HPI Flux Pro motors is 7 degrees.

Makes the issue worse as it's on min on the can & esc and it over heats? :(

Going to borrow another motor to eliminate other areas :(

Hi,
I used an HPI flux Pro 5T in my KP electric bike,at the RC bike world championships in lostallo switzerland,last week,the largest RC track in the world!,speed down the straight was up to 90 kph!...used it all week with no problems at all.....very good motor!...by the way i ended up 7th overall in the A final!
