64P is more for indoor track which you don't have much rock and stuff that would jam into the gear...but if your track is NOT carpet, even it is indoor, I would recommand using 48P.

Most ppl beside USA were using 48P because they run MOD and outdoor...48P gives you a better chance NOT to have little rock to jam into the bigger pitch.

US use 64P cause they vacuum the carpet (afterall, it is carpet LOL) and they want the best acceleration of the car, thats why they use 64P for a tad of more "punch". And yes, 64P gives you a finer gearing ratio compare to 48P but if you want concern about performance gain, there are NONE or at least, you cannot tell the different.

With 17.5, GT2 speedo...make sure get the 312a software, DRRS to #8, Timing to #7, motor timing to 10*, then gear to around 4.8~5.0. At least, I would start it that way....

adam text me big trouble in little china

is there a chart out there for the recommended range of FDRs on different motor turns and SPX speedo models?

Adam, appologies if you have answered this before (I did look around first). I'm running the GT 2.0 in my XXXT-CR with a 17.5 brushless. What software version do you recommend for this off-road application? Thanks. BTW the software it came with is doing great, but if it can do better....

Usually motors or escs have some guidance but that is based on certain tracks they have in mind. I know that they don;t apply on ours tracks

What software are you using now?

hi, anybody experienced the timing of their v3 motor to loosen up? mine's loose already considering i unscrew the 3 screws before adjusting the timing. now it moves by itself even if the screws are tight. is this a mfg defect or what? any remedy?

I don't know. I've had it for about 6 months, it's the Carbon Black edition and the manual that came with it is dated Jan 22 2009.

I wouldn't worry about it, I can happily move my timing rings by hand, without needing to undo the screws. It's why the silicone is there, as the two pads don't slide over each other without a little bit of force. Quite clever imo
If your really worrid about it, I see SP do offer a +10° locked end plate, and given thats where I'm running my motors, I'm quite tempted.

HiH
Ed

im just worried that if somebody bumps me the timing will move. will consider the locked plate as a remedy. the silicons don't help either since moving will not require any force as when it was new. don't know what caused this to happen either.

Where in the US can I buy a 17.5R v3.0 motor? I need it by Friday.
Thx,
John

Don't think they are here yet. Adam will be able to answer this for sure... But the last time I checked they weren't at Schumacher USA yet.

Ihere ya though... I need the same motor after this weekend HAHA

-DC-

More than likely you have the 205G

If you get hit hard enough on your motor to move your timing you have A LOT more to worry about!

We don't have them yet, I was told this morning they should be shipping to us this Friday

Good answer.... lolI <3 U DC

Oh yeah, to actually answer your question the 205G is a GREAT s/w for offroad, I think for right now you are already running one of the best out there

Maybe it's silly question, but where can we get newer software?

is it from here?
