http://www.hpieurope.com/graphics/parts/101822/101822_01x.jpg

We also have a unique attachable fan for inside the motor :drool: This secures via 2 grub screws onto the rotor and will kep internal temperatures down without any noticeable power change, very useful for high demand stock motors, will be BRCA legal when they arrive with us in a few weeks (around end of April). Very light and cool (pardon the pun)

Motors come with colour printed box, manual, 200mm sensor cable (black), extra metal shims for rotor spacing (no O-rings here!!) and colour decal sheet for the extra bit of bling.

Available from all good model shops now :thumbsup:

HPI flux pro motors are now in stock! :thumbsup:

MB Models have them in stock and listed on their website:

http://www.rccarshop.co.uk/catalog/index.php?cPath=23

Take a look at the price, absolute bargain!

Craig

[colmo]

I note the HPI Flux Q-base is a rebadged MMP - that's not a bad speedo! Nice price too at Modelsport.

The Sidewinder V2 doesn't appear to be sensored, so maybe something else?

[mikeyscott]

Anyone know who is stocking these motors? Particularly HPI Flux PRO 7.5T

Tried that :( everyone must be enjoying the long break..

Running a 7.5 and 6.5 V3 at the mo, but want to change to HPI. How much of a like for like is there, i.e. is a 6.5 HPI going to be like a V3 5.5? Spending a fair amount of ££ and don't want to land the wrong motor..

[mw02veg]

ask craig collingson. hes the man in the know and im sure he would be able to answer all your questions hes the hulk on here :thumbsup:

Guys,

Apologies for not picking this up sooner, I have been away !! :thumbsup:

It looks like these are due into us in the first week or so of May, If you want any of them get your local shop to get one on back order straight away as demand is very high and we already have quite a few accounted for :thumbsup:

I am running the 5.5 in my cat and my nefieuw is running my 6.5 in his bmax .
and we are both verry happy with the results of the motors as they are fast and verry smooth . good job Ben

[panch]

Just a heads up guys, We now have all of the usual winds back in stock :thumbsup:

[mikeyscott]

Hpi 6.5 for the 4wd from rc lazy then hopefully :)

[simoncrabb]

6.5, 7.5, 8.5 all in stock.

http://rclazy.com/blog/2011/05/10/hpi-flux-pro-brushless-motors/

[Whiskers]

How are people finding these motors?

[simoncrabb]

I'm running 6.5 in 4wd and 7.5 in 2wd and they are AWESOME.

I can honestly say they are as quick as anything out there, I was lacking nothing in speed on Sunday in 4wd, easily as quick, or quicker, than the 5.5 whatever in the car that won...

I had several people come up to me and ask me what was in my car, so that says it all really!

HIGHLY recommended. We're stocking most popular winds, 6.5, 7.5, 8.5, 10.5, 13.5

[Hulk]

I can honestly say these motors are nothing less than superb!!

Ive been running a 6.5 in 2wd and 5.5 in 4wd.

I made the A final on both days at Talywain National this weekend. The cars were as quick, if not quicker down the straight as any other car in the A-main :thumbsup:.

Had no issues with reliability at all.

You really can't go wrong buying one of these motors.

Will they be on the website any time soon?

[Whiskers]

Also what would be the best speedo to pair with these motors? Is it worth waiting for the new HPI Pro Flux speedo?

[Hulk]

Yes i would wait for the HPI Speedo. Not sure when it will be released, but believe me it will be worth the wait :thumbsup:

[Whiskers]

How do you program the HPI speedo? It is with a laptop or a card?

[Hulk]

The current HPI speedo that ive been testing is a one touch set up. You then have a seperate unit that you plug your speedo into to change your settings.

The only time you need to use a laptop is if you want to use the turbo boost. You download the softwear onto your laptop and programme your speedo from your laptop.

Like i say this is only needed if you want to run the turbo boost, otherwise you set up the speedo just like any other.

Again ive found the speedo to be second to none, so just think how good the final production version will be!

Defo worth the wait :thumbsup:

I bought the 6.5t HPI motor a few weeks ago and I have run it twice now. So far it is going great, a good improvement from my old Losi Xceleron motor. I am interested and would like more info about the internal cooling fan or rotor as I run a B-Max which is a heavy car and makes the motor run very hot. Any info would be much appreciated.

How does it compare to the xcelorin?

[evertonal]

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

[evertonal]

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?

[Ben Cosgrove]

Hi Ben,

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

[evertonal]

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

[simoncrabb]

Will they be on the website any time soon?

We put them on today:

Are the fans available Ben?

[Ben Cosgrove]

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.

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.

[Ben Cosgrove]

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:

[simoncrabb]

Really nice track!

[mikeyscott]

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

[evertonal]

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]

What motor timing are you running, car and gearing?

[evertonal]

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]

Is there any more news on the speedo?

[mikeyscott]

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

[Hulk]

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?

[mikeyscott]

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

[cmgreen]

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!

[mikeyscott]

6.5 or 5.5 on an 83 spur?

I've tried 83/22/23/24

80/23/24

[cmgreen]

6.5 standard timing, kit spur so 83.

[mikeyscott]

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.

[cmgreen]

Lrp sxx tc v1 no fan as well

[mikeyscott]

Lrp sxx tc v1 no fan as well

Does that esc have timing options etc?

[cmgreen]

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

[mikeyscott]

Ok many many thanks for the info :)

Dms regional on a tight indoor track next weekend

[panch]

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 ?

Dms regional on a tight indoor track next weekend

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

[mikeyscott]

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

[mikeyscott]

Tested again no timing on esc 83/24 shutdown.

Going to contact mb as reckon something faulty.

Got a big straight at torch.

[mikeyscott]

Just so I'm not going mad.

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

[panch]

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 :(

[simon]

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!

Regards simon

Just as an update, moved to another 4WD with similar FDRs and runs much better.

Will add that I also tried an Orion VST Pro in the SX3 and it didn't thermal.

I slackened off the belts two notches from SX3 kit settings, but never ran the car to test.

[arransmith27]

Hey there

I have just received my new Flux 7.5 this morning :thumbsup:

Can anyone tell me what the bag of metal spacers (2 x T1.3, 2 x T1.5, 2 x T1.7) which came with the motor are used for ?

Thanks in advance

[Ben Cosgrove]

They are for shimming the rotor if you want to change the std setting.

Very useful for when/if you want to use the internal fan.

Ben

[Mb3195]

Hi Ben,

Any recommended settings for a 10.5t at Ardent? I'm using a black diamond to its pretty easy to setup up, just need to know what fdr and how much additional esc timing you would normally run.

Cheers

Mark
