sparks....

rode one wit sparks n one wit hmf......the hmf had a filter n cam mod n teh sparks was still better (idk if he had a filter, but def no cam mod)

also the sparks full DESTROYED my GTYR slip

i'm thinking in advance???
 

Do we have any true dynos on these? I see this question asked a lot (for other model quads) with just opinion answers. Of course, there's always preference in people's likings, but anyone have reasons for liking one over another? Everyone suggested HMF for my Warrior, but I'm going T4 because I kept searching and found it does the most performance-wise for the money.

When you actually try it for yourself, let us know how it is.
