i ran the 4000kv yesterday for the first time. It's pretty good. I used Randy's rx8 setup on tekin's website. It was plenty fast (not the fastest, but maybe top 5) and had decent torque. This was in a dingo using 65 current limit, and a 14t pinion. Temps was ok. I didn't have a temp gun, but i would guess around the 150ish... I had pretty decent runtime. Also, it's a lot lighter! Overall, happy buy!

The guys at my track that's running 4600kv, they are saying they are tunning it down by 50%! and with that, it's still blazing fast.

I think i may try a 16T for more speed. But the extra speed isn't really necessary!

How would you say it compares to a 550 can. Is the 4000kv closer to performance of the 5.5? I have an sc10 so the weight should be close to the durango.

i say the 4000kv is more in line of the 4.5t, but a little smoother. it's weird. it has more low end torque than the 4.5t, but it's smoother. and it's easier on your esc than the 4.5t. I see the 4-pole 4000kv as an improved/better 550 4.5t. i was able to have apple to apple comparisons as i used the same 14t pinion. However, there were some esc differences.

4.5t 550
current limit 80
0 deg timing

4-pole 4000kv
current limit 65
10 deg timing

not much difference, but i just wanted to state it anyway.

i think the biggest improvement is efficiency, weight, and a little more lower end torque.

Note, i had the 5.5t 550 as well. I felt under powered with the 550 5.5t. I went back to the 4.5t prior to going with the 4-pole 4000kv.

That sounds good. I was running a 4.5 with the 14mm rotor and liked that but the rotor went. So now I am back to the regular rotor.

Debating waiting on a 4600 or just getting the 4000 now.

Which ESC are you running with the 4-pole motor? Will an MMP handle it?

what kind of run time you guys getting with tekin 4000,4600
also list your battery size.

Right about 12 minutes before she hit's LVC. I have since bumped my LVC up slightly so it is more in the 11s the last race I was at.

Ive got the 4000kv in my sc10 4x4 and needed to gear up on my local track. I haven't got a chance to try it yet. Plenty of speed on the straight but needed the extra umph in the infield. Temps have been good even in some of our hot days.
