At least Associated gave the 7.1 a couple years.

I love the minimalist blue look with most of the anodized aluminum parts (bulkheads, motor mount, steering rack, arm mounts, diff/spool) being black now! This looks super classy and legit!

Are 48P gears the gears of choice for asphalt? I see that the car is setup that way in the photos.

Everyone in my group runs 64p. I also use it for my off track practice. I originally ran 48p. But was limited to the size pinion could use. And despite running the same FDR, when I switched to 64p car felt completely different. It was not an Associated

In light of a potential pinion size limit, the apparently small range of adjustment on the motor mount of the 7.2 seems odd.

Most people run 64 pitch gears where I run (asphalt), but I've always thought they were too fragile and also very hard to set the correct backlash. So I run 48 pitch. I run 17.5 and 21.5 and I use the Associated/Kimbrough 69 tooth spur. That gives me plenty of ratios to choose from since I can run 34 to 42 teeth pinions and still have a good mesh. Oh, and don't let anyone tell you the 64 pitch gears are more efficient. They just sound faster.

Yep, I know a few that have them, built them, and raced them on Saturday for the first time. They look very promising

Mine arrived on Thursday and others are starting to receive theirs as well.

I believe standard distribution channels should have them in hand and you should be seeing more out in the wild soon!

I was able to race mine this weekend and I was happy with the first outing to be sure. There is alot to test with the new motor mount, and i feel like there's a lot of new potential in the 7.2!

They technically are more efficient, but it's so marginal that it's not worth mentioning.

You are correct. The higher pitch results also in a higher contact ratio. The higher contact ratio should give higher efficiency, but as you said, probably not measurable.

The real problem with 64p is that it will not stay efficient long enough to be beneficial vs 48p. From crashes, hot motor pinion temps, spur hub bearing play, motor torque, etc, there is no way to stay efficient without some of those teeth bending out of shape way before stripping. I was really amazed to see other racer's motor temps soar, while I was running way cool with my 48p gears....
