Yeah, I definitely need to do some experimenting tomorrow. I take it the general consensus here is that the Tekin RS and Mamba Max Pro really aren't faster?

My experience is that for the track size I race on, I don't see a difference.

I think on the big tracks from what others have said, maybe the other stuff is faster.

I look forward to the latest software updates.

it's ether that or watch TV

hey guys, I got everything pretty much my 1/12 ready to go, but I am noticing a weird stutter whirring effect on my V3.0 17.5 as it gets up to say 3/4 throttle, it seems to start shuddering.

Any ideas? This motor is brand new, just got it in.

Also, are there any issues running the 110 or 107 software on 1S lipo in 1/12? I looked in the thread but since 1S is shorter than allowed, couldn't really find anything.

check your sensor wire

Any news?

Ok. I tried 3 different sensor wires, same stuttering effect. I also went with a standard 2S lipo, and it wasn't as pronouced, but still happened. Also tried a 13.5 V3.0, same thing.

I then hooked up my GT2.0 Pro ESC. On 2S with the 107 software, worked fine for both motors. On 1S, started to do the stutter thing again, and the GT2.0 pro doesn't have a TQ booster hooked up.

So I am wondering now if its the software? I am going to go with 323 and see how that is. I recall something about software before, but can't find the info.

well, I just switched to 323, and it appears the software is the issue as now I don't get the stutter / whirring on the motor at all on 2S or 1S on the LPF.

reconfirming the various software, I tried 110 and 107 again. I must have been in 110 the first time as in 107 on 2S no stuttering, on 1S, it seems to go to about half throttle, then kick over, then as it gets close to the top end, it starts to stutter on 1S.

I am going to go with 323 for now. Only guy running speed passion at the track and race is tomorrow.

anyone know what 731 is for?

Before you change any software
Try To set Your motor Timing at max Torque first, it's a must.

Any Optional Firmware you will need is set at 205G first, since it's designed for
Maximum Torque.

Stutter mostly involved disconnected Sensored / sensored wire.
Double check, what is your sensor wire you are using now.
mostly stutter / cogging caused by bad sensor socket (female).

GT is not designed build in Booster,
You must have Voltage Stepup (booster) for
your receiver and GT if you are Running 1S.
if the supply to GT is not enough Stutter will happen.

Not to forget FDR also might affecting Stutter.

During run/on load.
Try not to reach Top End First (reduce your Constant Throotle).
Check how stable you are without stutter.

sounds to me like the esc isnt gettin enuff power to run on 1s so i would try a booster for the bec and b sure that u dont switch on the esc wen u use the booster or u will fry booster esc and battery

ok guys, I am using the following:

- TQ Booster
- Speed Passion GT2.0 LPF
- Speed Passion V3.0 17.5 Motor
- Spektrum SR3500 Reciever
- Futaba S9602 servo
- SMC 25C 4000mah 1S Lipo
- Spektrum DX3S Radio
- AMBrc Transponder

The booster powers the electronics and everything fine. I am switching on only the booster when I attempt 1S operation. If I try it with the ESC on, I don't turn on the booster. Either way, it still stutters as described when using the 107 or 110 stock software. With the 323 software, no issues. You can feel a difference in the power on the motor with the 323 versus the 107.

I have gone through now 4 sensor wires, I have a total of about 7 of them in the apporipriate length, not included the really short ones that the new motors come with. Its not the sensor wires. I have tested the motors on the ESCs on 2S lipo, NO ISSUES now.

Cain i have been telling you to set The Motor Timing at max Torque
what degree is yout V3 Timing is ?
and Set your Advance Software Timing at 0 Degree.

and the run the test again, with all four sensor wire ?

First thing first, and not to change the timing first.

are u running the capicitor on the esc ?

capacitor is on the ESC.

Timing is stock on the motors. running 22.5 degree as that is what I have seen posted by others running 1S.

Are you guys also running 1S?

wow thats a lot to take in
