Dont worry the xerun series older models and present the support will continue for many years to come including software development that i promise you.

Has anyone got a set up for HW esc/Team Power 17.5T motor ?? in touring cars
i'm using HW xerun 60amps v2,1. carpet track, fairly tight infield, 35m straight.

We were running our HW 17.5T motor but we seem to be lacking punch compared to the others (running Tekin etc) and struggling slightly to keep with them, so tried the TP motor cos it has end bell timing

Been running it with FDR 6.5

Any help would be appreciated

Does anyone know when racers in exile will be back up and running??
and whether they will have any of the HW V3 ESC's

I am struggling to make this speedo work with a graupner or corally motor.

I have an extreme stock and an SP speedo, both on 930 firmware and have tried both speedos with both motors and always get the same problem.

They always work great until they lose all the advanced timing. The green light on the speedo flashes which indicates the speedo has overheated ? however the speedo / motor are not even hot. I even disabled the overheat function on the speedo but it still had the same symptoms with the green light flashing and loss of advance timing. Admittedly if I tried it an hour later it would be fine again.

Typical settings :-
FDR 5:1
Boost 50
No turbo
DRS 2
RPM /ACC 400

This problem can be after 1 minute or 4 ? I bought a second motor but it still did the same.

I have run with turbo and without. it makes no difference - Has anybody had this problem / know a solution ?

Thanks in advance

I tried the Graupner 17.5 and was the most powerful of all those I tried, but it is a motor with considerable mechanic timing, which if combined with plenty of electronic timing can create reading problems of data sensor and switch in sensorless mode(fash green led), I managed to get it working properly having the lowest electronic advances.

I do not know that wrapping uses, but with 17.5 advances should be around (9) and 30 ° (12) 10 ° at most.

I've had the same issue with the 930 software on three different motors, its as if the car goes in to sensorless mode for no apparent reason.

I solved it by turning off the low voltage protection. I think what may be happening (especially with the corally) is that the power used on the motor under sever load suddenly drops your battery voltage below the 6v, once it does, the esc switches into safety mode.

Since i've changed the cut off, I've had no issues - try it and let us know!

Your settings seem fine - although I would give it slighlty less boost with a little bit of turbo - then watch it go!!

Thanks for the replies.

It sounds like it does go into sensorless mode for the reasons you have mentioned Agno.

I am running 13.5 but can you share your 17.5 settings and I will adjust accordingly.

Thanks

JamieV

Sorry, I had turned off the overheat function. Do you set the voltage protection to 'None'

Thanks

Try these, I have used on them with a Corally Pro Red 13.5
1 1
2 1 0%
3 4 3v
4 3
5 8 100%
6 4 100%
7 2 0%
8 1 6%
9 65 64
10 4 18%
11 1 Enable
12 1 0
13 7 7000rpm
14 4 0.3 sec
15 10 500

by having 12 set at 1 - 10 & 14 don't matter

FDR 5.71

These were on 211 stock, so should the same on 930, in fact 930 should be better.

Have you done the tape modification on the sensor board?

take the sensor board and put some pvc tape on the side that faces into the motor, cut the hole for the shaft to the size of the whole on the sensor board.

Used this succesfully on asphalt.

Yep, turn it off!

You're fine to run 60 degrees of electronic timing on a 13.5t Corally pro red......it will be quick though

JamieV

Thanks - Will try it this weekend

JamieV

Thanks for settings - No, I didn't know about the tape mod, not sure what it does but I will make sure I do it before trying out this weekend

This is usually a sign of weak batteries which can't handle the current or plugs that cant handle the current.

OOPs got it the wrong way round, put the tape so it is facing the endbell!, you need to unscrew the board, put the tape on, cut the whole, then screw back on, making sure you don't overtighten the screws.
it just stops any possibility of it touching the end bell, especially in a crash and causing the motor to go sensorless.

First off, hi

I have a extreme stock 17.5T and came with 518 installed on the esc, I race 1:12th carpet

I wanted to see what other options there were on other software so flashed it to 930

There are more choices with 930 but I don't have the option to reflash back to 518, where can I get this?
