Hi,

Would it be ok to replace the capacitors with a single one like the Tekin has ? I'm only asking as it's tight on space in my car.

Thanks.

Martin Hofer

no it would definately not be ok. the speedos get delivered with as many caps as they atleast! need. using less will cause the speedo to break

New soft version -->13.1 now auto storage of the data after the heat is improved.

Hi there,

Can anyone provide me the product id / reference for the sensor cable that comes with GM120 V2 ?

Is there any different cables, with different lengths ?

Using GM120 V2 and GM Pro motors.

Thanks

Does GM have software out yet where u can hook to computer to change up timing and boost?

John_S

They have had software out to do that for several years now. It is located on the download section of the gm website.

Is it safe to use a 13.5 x12 motor with a 2010 gm 120? Any advice Martin?

I'm running an x12. Temperature is a real problem to keep under control so at the moment for tight stop start indoor track i'm running:-
four dot insert on the motor(-10deg)
15 deg variable dependant on the controller
90amp current limit
6.03 FDR
and a big fanless heatsink. This runs at 85-90 degrees c. Any more than that and there is a lot of fade despite plenty of clearance to the cut off temperature.

One thing i have found is this motor is real fussy about the gearing so yours might be different.

Thanks for the reply has anyone else got any more info about the x12 motor gm combo

Hi there,
I am looking for an alternative for the SP 13.5t 138135V3.
Was thinking of the GM 97303. I now many things about the SP, some things about the X12 LRP 13.5t but nothing of the GM 97303 13.5t.
Where can I find info on, or can someone provide me with info on:
- timing of the motor, how to set, what values available, built in timing
- how to gear in comparison to SP13.5t en LRP X12 13.5t
- is there a manual somewhere out there of the GM 97303
- how does it provide it's power? I mean for instance more power with low revs, or medium revs or high revs? Or smooth the whole powerband? Compared to SP en LRP.
- how about temperature at different FDR and with LRP SXX Stock Spec?
Looking forward to your response.
Kind regards,
Ken Sei

Hi,
I am considering the GM 97303 13.5t in combo with LRP SXX Stock Spec in TC1:10 rubber outdoor.
Now a lot about SP138135V3 en LRP X12 13.5t. But nothing about the GM 97303 13.5t. I would like to start using this motor as an alternative to SP and LRP.
Please help on:
- FDR on short, medium and long circuits
- temp, easy to keep low or not and so on
- powercurve, smooth like SP or for example more power middle and high like LRP
- timing, what and how to set, in combination with SXX
- can someone provide with a manual of this motor
Thanks for the help.
Kind regards,
Ken Sei

Hi,

I'm using the GM75 with the GM13.5t I've tried both rotors 1600+1300 and prefer the 1300 as it doesn't get as hot or fade after a few minutes. Gearing I use 4.7-5.0 outdoors and 5.5-6.0 indoors. I would like to try the Graupner motor would I still use the same gearing ?

Thanks.

the graupner motors are like 1800 gauss or something, so if you didnt like the 1600, then you will most likely not like the graupners.

I'm surprised you said the 1600 rotors ran hot, as I always thought higher gauss rotors ran cooler, but that may be my mistake in thinking.
