3.5 is too hot for offroad, if u must, then start with a 16t

According to Novak, here at their site

http://www.teamnovak.com/tech_info/b...r_gearing.html

They do not recommend a 3.5 for 4wd.

Now, you could go with a 4.5 and follow their recommendation of a 17 or a 18 . Their formula (spur/pinion) x internal drive ratio = FDR they recommend a FDR of 12 , a 17 pinion will give you 12.35 and a 18 will give you a 11.67 .

I have found they are pretty close, with this formual and their chart.

Good luck.

Why keep making new threads everytime you need to ask something about the B44?

Just post here http://rctech.net/forum/showthread.php?t=171866&page=49, thats what the threads for. :rolleyes:

3.5 is by far way to much motor for any thing off road. You will be so pissed at your self for wasting $80 on a motor that you will not be able to do anything with. 5.5 is the lowest turn motor that Associated is recomending, at least that I can see.

As for the 4.5, Personally I still think it is way to hot and it will still overpower the b44. Slower is faster 9 times out of 10 especially when your teetering on the fine line of motor overkill.

Just my .02

Too Fast
 
I was running a Novak 4.5R system in my before, running 87 / 16 equalling FDR 13.6:1 and I melted the GTB.

I ran a 5.5 geared 21/78 and its STUPID FAST, going to get a 6.5 or 7.5:rolleyes:

Running a 6.5 with a 19 and stock spur

I wouldn't go under a 6.5 for 4wd off-road.
