My comment was towards your comment "WHY in the world would you want to make your vehicle slower" not on the legality of a slower motor.

2wd open is the only class that might benefit from the 2500kv motor and any motor is allowed so the legality would not be an issue.

In Box Stock, the rules say "OEM White End bell Motor unmodified, 7T Pinion are both mandatory" so you cannot use a 6T. As for motors, you have to use one of the motors specified, so no 2500 in Stock.

Thanks Panther6834, Traveler2 and Poor_Boy for the clarification. I had the impression the stated pinion and motors in the rules were "limits", and thought of downsizing the motor as I feel 3500KV was too fast for M96 tracks. Looks like apart from Open 2WD/4WD, I'll have to continue limiting the motor power at transmitter/ ESC.

What about the Audi R8 (in comparison to/against the NSX)?

I've been running the SC430 Petronas on my 'Box Stock' (MR-03), and the McLaren Senna on my 'Stock' (MR-03 EVO, soon to be replaced with a PNR2.5). I'm strongly considering "retiring" the Senna, moving the SC430 to the PNR2.5, and getting a new body for the MR-03. I've already picked up an R8 (MZP246AS), but am still undecided whether to run it on the MR-03, or my MA-020 'AWD Box Stock' (our local club runs an 'AWD Box Stock' class). If the R8 ends up on the MR-03, then I already have a body in mind for the MA-020...but, if I decide to put the R8 on the MA-020, then I need some other "options" for the MR-03. Once I can get the Mini96 track set up, I'll start gathering times for M96 WC (btw, the EVO will still be used, but for another M96 WC class). And, yes, I know that, technically, I could run the same body on more than one chassis/class...but, like most, I'd prefer having different bodies for different chassis/classes.

No worries...all is good. The not-so-wonderful thing about forums is that, when someone replies, it can be difficult (sometimes, impossible) for others to determine if the person was serious, joking, or somewhere in-between. That happens to me a lot when I respond with sardonic humor...lol

That works...or, you could learn better throttle control (something I am, admittedly, still working on where Mini-Z is concerned). An "idea" that combines both of these is to limit the speed via ESC, or Tx, to a max speed you can control...and, then, as throttle control gets better, gradually increase it, until you have removed all 'limiting'. If you start at, say, 60%, you could increase it to 65% after a few weeks...then 70% after a few more weeks, then 75% after a couple more weeks, and so forth. Before you know it, the ESC/Tx will be at 100%, and you will have the throttle control to use that motor on any size track. That's what I'm doing...and, so far, it's helping (I'm now 'crashing' far less than I'm 'driving'...lol).

I think the NSX is more forgiving on the walls than the new Audi R8 body you referenced, but its what I run so I may be biased. I have several of the older R8 bodies that are great, but I haven't tried the newer one yet.

"Old", or "new", shouldn't they be the same? I mean, the only differences should be the colors & graphics. I can't claim to actually know...but, I would assume they're made using the same molds, and the same plastic. Again, just my assumption.

They are not, which is why I was drawing a distinction. The older one is wider and has a more rounded front so more forgiving on walls. I’d suggest finding a picture of both and comparing them, but we are getting off topic here. Your inquiry might be better off in the Kyosho Mini-Z Series thread where it might get more views and input.

No worries...was just curious about a comparison, especially as these (ie. my) cars will (sooner or later, hopefully sooner) be used for World Challenge. Although, technically, both bodies should probably be reserved to the AWD class, as both bodies are actually AWD cars. Whether for World Challenge, or local clubs, shouldn't RWD classes only allow RWD bodies, and AWD class only allow AWD bodies? Again, just curious.
