i run the 5.5 in my B4.i really like it.we run on a large track that caters to 1/8 scale so without it i have a hard time making the jumps.with the 5.5 i have no problems.car is smoothe and fun to drive.for a smaller track it would probably be too much motor

99% of racers will need no less than a 7.5 BL with a bonded rotor. I have run the LRP 7.5 motor in my B4 with both 5 and 6 cells and creates more than enough power. A sintered rotor will give you the potential for greater speeds but in the case of a 2wd off-road buggy, its best attribute is that it will give you more "mechanical" drag brake so you can use lower ESC drag brake settings. It will also last much longer.

I actually would prefer to run an 8.5 if it was an option.

Yeah I agree, a 7.5 or even 8.5 will toss a 2wd buggy around pretty good. I like a 6.5-7.5 in a truck and 5.5-6.5 would probably be great for 4wd.

I went with a 5700 as I liked how it felt in my stadium truck.

It should be very fast and fun. To me a buggy feels a good bit quicker vs. a truck running the same motor.
Have fun.

ManicRC,

That is because of the traction issues we face at Socal. One hour it's hooked up and the next no traction. It is hard to run the same setup at Socal.

Default spread spectrum GTB

Does anyone have the spread spectrum Gtb and is it worth the difference in money?
Also what is the difference between the ss 8.5 and say a velocity 7.5, besides ribs on the can.
i am in the process of getting new stuff for a xxx-cr which I ran a 5.5 velocity turned way down in last year but there appears to be some new technology and would like to have some more info before i decide.
Thanks Guys!

Default 6.5

I run an LRP Vector 6.5 in my B4 down here in FL. Seems to be a pretty good match to the track, which is a decent size, but lots of turns and jumps and such. It has plenty of punch and enough top end for the straightaways.

I run the 7700kv mamba on 5 cells and 6 cells when I want to freak people out with the insane hp.

well as alot of people have suggested, any 7.5 with a sintered rotor is perfect in the buggy, which most have said is similar to a 6.5 bonded.....

the novak gtb 7.5 sintered combo is lovely in the buggy, i would guess, all i have ran in my buggy is a 13.5 (because i only have two 13.5s and one 7.5)

i plan to run a 6.5 in the truck (after running the 7.5 in the truck and it feels like a buggy motor)

the 13.5 is always a good option for most club racing and bashing. geared 81/24 in the buggy the 13.5 is crazy smooth.
