gear down on the spx and then gear down again and let it rip smaller the track more gearing down. love the spx - i will be buying more wanna sell?
Once I put it on profile 7 and geared down several teeth, I became an SPX believer! I may end up picking up another one in Nosram red to match my Photon.

Running a 13.5, I ended up around 5.71 on a track a little larger than Fastlane. I'm running a SP 13.5 with the timing right in the middle (from the factory) for what it's worth. Once I geared down, the car came alive in the infield, and profile 7 really lets it rip on the straights, especially toward the end. On a bigger track, it could get scary. We're expanding in a few weeks, so I guess I'll find out.

What is the main difference between the SPX and the SXX? Is one considered better or faster? Different purposes? Thanks.

The SPX is more for spec racing (17.5,13.5) and the SXX is designed more for Mod racing.

With this setup, we hooked up the fully charged battery, the esc came alive. we did the setup, it didnt work at first. so after checking the to do list we noticed we forgot to reverse throttle.

the second trial with correct setting, everything worked. Forward, brake. I corrected the servo hornas it was off a little I put the car on the bench and we were chatting with my friends getting ready to check the modes the ES started smoking and burnt.

This is the second SXX TC Spec that died on the bench and the 3rd to burn in this area and everyone has questions...

The only thing thats common with these setups are the spektrum receivers. or faulty ESCs.

I replaced the SXX with my spare and put a new Futaba HRS 27mhz PCm receiver and all worked fine.

I used the old TC spec with this receiver with no problems for the whole season last year. So my question is,

Is there a problem with SXX TC SPEC and Spektrum working together or I was unlucky and received a bad ESC?

Second is what do I do with it?

Question regarding the Lipo cut off:

Does the whole car just shut down or does it leave you with steering?

With regards to people discussing SPX vs SXX TC.

I see people saying the SPX has special advanced timing and profiles for stock spec that the SXX TC doesnt have and the SXX TC top profile not being as advanced as the top profile on the SPX. My question is, is it not possible to catch up by advancing the motor physically ? Or is everyone advanced the motors as far as they go already?

Ive just purchased the SXX TC you see and its all ready to go for tommorow nights racing, first time ive had a brushless system trying to find out a bit of info. What profile would you recommend? Im running 10.5 Vector.

Higher physical timing won't provide what you get with SPX Stock Spec.
On high profiles you won't have high esc timing from throttle bottom but it raises dynamically timing when you've got full throttle - mostly on straights. So you've got great bottom end and also top end. With SXX and physical timing you can get only bottom end or top end not both.
I would use highest profile on your SXX for sure but it still will be lower than highest SPX profiles. Reason is - SXX is designed for mod where you don't use such high profile timing - motor has plenty of power. SPX is designed for stock motors to provide as much power as you can get from motor and even more.

Thank you for the reply. In your own personal opinion would you say theres a massive noticable difference between the 2 speedos with both set on top profile?

I belive that somewhere here on forum (other thread) was mentioned that SXX highest profile is like profile 6 ond SPX. Dynamic timing is on pofile 7 and 8 if I know well. When SPX starts changing timing it's like second gear on car. It's crazy.
Personally I ran SXX only with mod motors so I can't really compare these two. Sphere TC Spec and SPX is HUGE difference - mostly on straights.
