Never forget that first place goes to the racer with the MOST laps, not the racer with the FASTEST lap

No, sir!

The FNRS popped up on Facebook in mid-November but there's no indication who is involved in its creation or management, which is kind of interesting.

 

The poster above is clearly Ralph Thorne's work to my eye, but whether he's the FNRS "guy," I do not know.

I really like the rules for this new series, but I do have a few comments (not all bad!)...

 

I would add that a "reasonable sized" (no bigger than 3/16" in any dimension?) notch in the motor is allowed to clear the rear axle.

 

I love the 10 tooth pinion rule, really keeps tuning time to a minimum, especially for the less experienced racers.

 

I would clearly state whether aluminum pans are allowed. One the one hand you say that lightweight steel pans are allowed, but then you say that parts from the same manufacturer can be interchanged. To me that is confusing and sounds like I could use aluminum pans.

 

Allowing tape on the bottom of the chassis just says you can add lead tape (as well as other types) there. If that's what you want that's OK but realize that people are going to add lead tape on the bottom unless you state otherwise.  It's my opinion that not allowing any tape on the bottom removes a lot of confusion and makes it easier for all.

 

OK, that's my $.02 worth, probably worth a lot less in the real world!

 

Oh and finally, I'm looking forward to competing in the new series!!!
