Thanks Wild Cherry. Appreciate the input:nod:

my local track most people run like a 35 -36 with a 69 spur would the car be different if u ran like a 30- 72 . with the 69 spur i have plenty of speed just a little soft on bottom. sorry guys i dont know much about gearing.

if you want more punch, you can drop a couple teeth and check temps. 30/72 is way different than 35/69. I am not sure i would go that far in what I assume to be 17.5

yes 17.5 d3.5

72/32......and when I run the 69 it's 69/34. This is with Tekin Gen2's

I ran 72/32 for a long time, but that gearing was with a different 17.5 that made more rpm, so it worked out well. Also ran 75/32 on the last Short Course Shootout track here and nobody else could run that same gearing and make the jumps like I was. Was kind of funny listening to people complain about it too.

I'm running 66/33 right now and loving it. Ran it with 34 and it was faster but didn't like the bottom end, and temps were a little warm for my taste.

I want to go lower than 66 but haven't found anyone that makes a slipper spur smaller, and my current Avid is the smallest they make.

Your running a final drive ratio of 4.80, so you can achieve the same ratio using a 72/39 setup

It's 5.20 actually, and pretty sure that wouldn't even fit.

Running the smaller spurs also move the motor closer to the rear axle, which changes the weight over the rear axle. Another small tuning aid for rear traction and rotation.

I had the wrong internal gear ratio, not sure where I came up with 2:4:1

The B4 is 2.6:1

What are you doing in here you traitor!? ;)

If you only knew...:sneaky:. Let's just say from time to time I get bored and try something different....but always end up back home.

Thats what I like to to hear! Haha. How'd the Shootout go for you?

wait is AE your mistress or TLR? or are you just cross dressing rc cars now?

It was ok, finished 5th in 17.5 and 10th in 13.5. Happy to make both A's.
