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!
