Yes they are,both brand new 21.5 Thunder Powers.
Thank you for replying.

We have tested turbo functions on the 150 amp and the amount of frequency noise from the motor causes the esc to go from sensored to sensorless .

Motor noise is a major issue at the moment and to be honest i can't see michael releasing any software that will not work and cause major reliability issues.

To produce turbo even with small settings we feel that the software at the moment has more than enough power .many do tell me we need to tone it down not tone it up .

again this is for onroad 1/8th ! we need more speed. thats fine, ill off load my HW stuff.

XSLR8

Both motors cogg even with the sensor lead unplugged !
The only way to stop it is to retard the timing on the motor to less than zero.

thunder power need run 25 on motor

XSLR8

Anything over 0 and they cogg badly,settings I have used as a start is the pre-set 17.5 v3 settings with FDR of 6.1

Add a bigger gear or more cells. I don't know your situation, but there has never been a time when the larger motors could be boosted. In most cases the loss in efficiency is much greater than the gain in speed. I have been running a T8 motor in electric offroad with a MMP for a couple of seasons, and it has never been wanting for power. I can understand wanting more top end, but boosting does not work well with large sensored motors. Even the tekin guys don't run in sensored only mode for their large scale stuff. Try a higher KV motor to get more RPM. Or adjust your gearing, and add another cell. Another thing to consider is the physical limitation of RPM on the rotor. Most 4 pole motors are not rated over 80K RPM, so if you are running 6S and a 2600KV motor then you are approaching the physical limit of the motor. If you can't get the gearing to give you enough top speed then add a 2 speed transmission, just like you have to do in nitro. Or 3 speed if the track is really big. Electric is cool because for the most part you don't need to do this, but the RPM range is not unlimited. Adding timing on the smaller motors is possible because it actually adds efficiency and can create more power with only a small amount of loss due to heat. The larger the motor, the more efficient it is and the less power you can get our of it by boosting or adding physical timing to the can. In another thread a couple of engineers where explaining why they don't boost larger motors. But the bottom line is that you don't get anything out of it, just heat, and significantly less run time.

Track: Asphalt, med speed, 50ft straight
Motor: LRP X12 13.5 0000 timing insert (27.5 deg)
Fdr: 6.44
Boost: 27deg, 8k-15k, linear.
Turbo: 5deg, 20k rpm, Acc 15/0.1, Dec 18/0.1
Temp: 95deg C (Air temp 36 deg C)

More aggressive settings are possible with more power but I'm not too comfy with the temps.

If I update my program box to use whit the V3 can I still use it with my xtreme stock

You will only be able to use it as a link with the HW software. It will not work without the computer. The boxes are cheap enough I am just picking up an extra one.

Not tried. Don't get much track time due to there being no tracks near me.

It's survived 120c temps before and consistant 100c temps after 5 min runs. It's a tough old blighter!

there is no esc combo on the planet with turbo functions.whatever you buy you will need more speed.run a 6 cell pack.

have you tried a different motor? meaning brand not wind

did you try different batteries?

XSLR8

Batteries I use are Fantom 6500 which are new and work fine in my 13.5 car with the old speedie.
Have not tried other motor yet,but will so I can work out whether it is esc/motor combo or speed control problems.
Cheers.
