Thx for the answer, but the strange thing is that I thought of it the same.
So I went to another mode just so the esc could get my transmitter values (at 100%) but it didnt change.
I noticed it would give full throttle about halfway the trigger so I started adjusting the EPA and ended up at 65% that the esc saw as full.
Very strange, I'll try again this week and see what comes out.

Hi Matt, do you need to run a lipo booster when running with 1s liops? cheers Aaron

Aaron, Personally I ran with a 6.6V LiFe reciever pack.

There's a setting that ignores radio calibration when changing modes, make sure that's not on when you try to change modes.

Hi
have a strange problem with my 120 speedo , other in our club have same problem with the 75. We run 17,5 blinky. Problem is with gm and also other motors. I run around 4 gearing in a TC on rubber tyres. Problem is when the car starts from stand still. Looks like it will reverse , but just 2-5cm then forward the same , then reverse again , and then suddenly it goes normal. But if you stop on the track it's same problem again. Max timing on motor and in 2 on speedo. Speedo is updated to 13,1. Any ideas ? Sensor cable has been changed many times, no result , many different motors.

Hope you can help

Thanks in advance

Turn the timing down on the motor a little and it will stop

I had the same issue with a 13.5 Reedy motor

It will still be mega fast as you don't need loads of timing in Blinky just gear it harder :-)

Hope it helps

Hi
Thanks for your answer , BUT something must be wrong in the speedo , just heard that one of the guys change his GM with a SP speedo , and no problems at all with same motor timing.

Had exactly the same issues today when running blinky for the first time.

With an X12 motor on minimum timing (4dot) it was fine. With any more motor timing added it would have this jerky getaway, which caused me a slow getaway starting from pole in both final legs, with P3 man almost coming past me each time.

If there are no solutions from GM then this ESC will be coming out. Such a shame as I love it in boosted mode, and it's totally bullet-proof apart from these cogging problems.

Hi

Try to look at GM own forum.

http://forum.gm-racing.de/forum/

Ralf Heilbing is answer at this forum , and keep saying that there are no problems. Today I put in a Tekin RS pro , and same motor and gearing , and in blinky ,and NO problems what so ever. Like I have mentioned , 4 different drivers have now that problem in denmark , and now 3 have tried new speedo.

try a couple of clicks of fwd trim on your handset, we used to have a similar issue to this with boosted, so i doubt it's blinky mode.

I don't think it's blinky mode either, as it was fine on minimum motor timing. The issue just happens to come up when running blinky as you tend to add motor timing, which seems to be what causes the issue.

The trim trick was necessary (and worked) on the early 2010 GM120s as they had a bootloader issue. But that happened even on minimum motor timing, and actually caused the car to totally stall and need a push, rather than just cog a bit. This was fixed by the time the GM75 came out (which is what I'm now running), and the issue seems different. I'll give it a try anyway and see if it helps, although it'll likely be a while before we get another dry weekend to try it.

Can some of the other guys with the issue give it a try? Basically you need to move the throttle trim forwards far enough that the ESC is no longer in neutral, but isn't quite far enough forwards to make the car move.

have the same problem with the GM75 if i resert factory works well on 0 timing but if i starts with timing do the same.
Any help with fdr for a open track 80m straight motor x12 and V131_basic.gd2
