Most I know are in the 6's and some 7's, but there are the odd exception.
But whatever works for him.

and your post wasn't constructive either
I totally disagree with the FDR sounding too high. I've run the SPX to 9.0 FDR and have found that far and away the best, in combo with a Novak 10.5ss with full timing/punch 8. This is on an indoor track with a medium length straight. Before the latest Tekin firmware came out, it was the quickest thing out there.

That "occasional" hesitation is due to sensor errors, we have seen that as well sometimes during testing. It doesn't happen to everyone and not very often, but usually can be fixed with finetuning the motor as it is actually a problem of the motor itself and not the speed-control.

What we have found during our own recent testing is that all these new "super powerful" algorithms are sensitive to proper sensor alignment inside the motor, if you have a motor with too large distance between magnet and sensors or a misaligned sensor board (not entirely parallel or offcenter to magnet) such problems can happen. It seems as problems are much smaller with our X12's, due to the very precise sensor alignment, but some of our competitors motors are more prone to sensor misalignment and therefore that results in more of such "micro stuttering".

Also something to consider is wiring, having sensor-/power-wires wrapped together can already cause massive problems! So it's better to have them completely separated.

We're also looking at ways to improve the sensor handling inside the speed-control even better then it is in Mk2, so it works 100% even with poor sensor alignment. It's my job to consistently improve the product of course...
Does it cause any damage to the motor when this happens? I am already using an X12 motor and have my power/sensor wires separated. I see the problem maybe 5-10 times in a race day. Once the car is moving at a good pace I usually don't see it.

It depends on the motor.
The Speedpassion motors must be geared heavier than the Novak and the Tekin motors.
I drove a Tekin motor with a gearing of 6,9FDR wile others were driving 5,4FDR or even heavier. As they did the same with there motor, than they lost top speed and there motor became to hot.

You're right. I had to go down to 5.8 to get a 13.5 Speed Passion Version 1 working ok with the SPX on punch 8.

I have several motors and all need other gearing.
The GM must also be geared heavier.

As you gear a Speedpassion lighter it looses all it's power.

Thanks for the info. Like the post below, mine does not cog all the time...just a few times during a race night. I'm not opposed to trying new motors, but it looks like the x12's are having the problem as well. I guess what I would like to know is...should I send mine back to AE in hopes I will get new ones that do not have this problem or should I test new motors, gearing, and timing?

Anyone noticed that when they turn their speedy off, you get a little kick out of the motor? Not a massive issue, just different

I did and I would say its right there with them, just need to dial it in a bit and I think it''ll be faster.

FOR PEOPLE GOING FROM SPX or SXX to the new SXX S.S.

throw everything out the window you think you know from your sphere, spx or sxx...

this is so different!
I'm talking 13.5, off road, but I will say I went from a spx (or sxx for that matter) to a sxx/ss and it is learning all over again.

I went down 9 teeth on the pinion and my motor still comes off 40 degrees hotter than ever, uses 75% more of my battery and actually gets the esc hot!

I loved the spx and sxx for ease of use and set up, I'd consider them dummy escs... where as the sxx/ss seems to be more 'expert only'

being that there are just so many more factors...
feel... 000 vs.0000... boost... etc, and undrgearing heated up my motor worse than over gearing.... definitely a new issue for me in the world of stock motors!

I think if you are hoping to buy this, tape it down and be faster... save your money!

the speed this esc can deliver (although substantial) comes at as cost of smoothness, ease of setup and reliability... you could easily spend a whole day just figureing out gearing and settings on this, so if you need to spend time figuring out anything else on your car do that first.... and plan on spending 10 runs dialing in this very advanced speedo
