9l in crt .5?
 

anybody run one before.....I want to run just 3s or 2s in this truck...using a mm no bec?

stock spur and I want maybe 40-50 mph

There are a few who have run that and like it. Stays relatively cool considering it's a Feigao. But, if you run 3s you should still use a BEC IMO...

I will use a bec than .......what pinion would you suggest and its mod1 correct?

Pinion depends on speed you want really. And yes, it's mod1...

well I tried to use the calculater but it didnt have a choice for a crt .5 spur
and I dont know how many teeth are on a stock crt .5....I know I know go count the teeth.....to lazy right now:angel:

crt.5 spur, is the same as 1/8 buggy standard spur, 46t.
And if you want my 1509, 2.5d/s (2700Kv), i can sell it................:whistle:

oh yes I offered you a trade....but I just sent a pm for price


the 9l is about the same kv and a heck of a lot cheaper but I know the neu is much better quality

i ran the calc with 46 spur and I cant hardly get it below 65mph....lol....you would need like a 10t

65mph? What settings did you enter?

lol....I see what I was doing wrong....i was entering 1/1 for diff's

btw there was no stock spur at 46t...you sure its not 48t?

The stock spur on mine is definitely 46t...

The stock tires diameter on the crt.5 is not 4.0, but 3.5:smile:

The spur is 46 yes

The 9L runs pretty nice. Has good power, runs pretty darn cool also.

But if you can swing that Neu, DO IT!

And 4 in is std 2.2 truck dia, so 3.5 is buggy. Depends on what he is running

hint hint:rules:

My crt.5 will have my Neu 1512, 1.5d/s on 4s, with proline bowtie 30 serie.
SHould be nice setup for bashing:intello:

It's not listed under Ofna because the ones there are "specialty". At the top, right under Miscellaneous, is the 46T spur. :wink:
