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?

[BrianG]

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

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................

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

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

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