I suppose the entirety of this statement was lost in translation.

Let me clarify: I was attempting to convey that I can't say anything regarding 2S setups(in fact, I don't know of any tracks that allow 2S and also allow E-buggy, most instantiate those rules to eliminate people bringing things like E-buggies) as I would never have interest in running an E-buggy on 2S. At that point a mod wheeler would be much more suitable IMO. But either way, just trying to offer up my experience that the Hobbywing motor seemed a little more powerful than a Tekin of the same KV rating. Maybe that will translate to higher KV motors as well.

Unless you're running clean 10 minute mains and consistently qualifying for the A, either brand will be more than suitable for the application. They're both very nice, can;t go wrong with either. Support your LHS and go with what they carry(which looks to be HW, in this case).

First, it wasn't lost, so no worries. I've mentioned the 2S limitation in a few threads. I plan on soldering 5.5mm bullet connectors between the ESCs & motors of most of my vehicles. This way, I can used 2S & appropriate motors (such as a 4000kV) at the local track (and other tracks only allowing 2S), and 4S & appropriate motors (such as 1900kV) at other tracks. As for the "support your LHS" comment, they carry HW, Tekin, and a few other brands.

Temporarily ignoring the motor, and only concentrating on the ESC, the primary reason for them recommending the HW over the Tekin was cost (obviously, HW costs less), but, honestly, I don't mind the higher cost, especially if I'm able to maintain consistency in ESC programming. In other words, whether motors are all Tekin, all HW, or a mix of both, if all ESCs are the same brand (Tekin), the programming between all ESCs is, essentially, the same. Using MS Word as an (unusual) example, if you used multiple computers, would you rather have the same version of Word on all computers, or a different version on each computer? That's why I'm not so concerned with the brand(s) of the motors...really, only the brand(s) if the ESCs. Does that make more sense?

In that case, I would take other factors into account: reliability, warranty, ease of switching profiles for 2S/4S setups. I have seen a lot of HW stuff kick the bucket at my local track, Tekin not so much. In my experience, Tekin has far better warranty service. Finally, Hobbywing takes the cake for adjustability as it's just easier. Get their little wifi module, and you can wirelessly change anything you want on that ESC, all on the fly. Tekin has something similar with a bluetooth module, but it seems(to me) like HobbyWing may have a nicer software setup. Also note the Hobbywing 1/8 ESC's are passively cooled, while the RX8 is actively cooled.

Yea...but it what it is (it's also A ROAR-sanctioned track...one of only 13 in California). That's why, for my track vehicles (race & non-race) that might normally run on 4S, my plan is to have two motors for each - one for running 2S, and one for running 4S. The two 1/10 4WD buggies (the 8ight-XE, and the other one, which I might convert to 2WD at some point) would have a 4000kV for 2S, and a 1900kV for 4S.

As for size, I'd estimate it's approx 30' x 60-70', with clay surface. Its current configuration (they reshape it from time-to-time) has a fairly even balance of straights vs curves, as well as flats vs jumps. On the technical side, I'd say a 3-4 out of 5.

I don't understand, you're increasing kv but decreasing voltage, what's the point? You end up with similar RPM but higher temps/less efficiency, or am I wrong... just seems weird from perspective of organizers. I would think the issue of running 8th scale on a small 10th scale track is track degradation from larger tires, not battery size.

As illogical it may seem, I'm sure they have some reason. Besides, what can we do about it?
But it's not the point of the discussion, so lets just work with what we got?

I don't know if HW offers any moters that makes sense with 2S but wouldn't Tekin Pro4 4000kv be something to look at? It might not be suited for the additional weight of a 1:8 buggy vs a SC truck, but I can't think of anything else that could be in that league.

I've ran the Trinity White Carbon 5000 4S and Orion Carbon Pro 6500 4S. Both fit perfect.

If I knew the "why", I'd be able to explain it here...but, I don't, so I can't. It doesn't make any more sense to me than it does to you, it to others reading this.

Again, I don't know the reason, but, as you said, nothing "we" can do about it. The shop/track owner might have set the rule, the city might, or even the country...don't know. As for the motor & ESC, already have the aforementioned HW 3660 4000kV & XR8 Plus, but want Tekin options to consider. To completely simplify things, it, basically, breaks down to these three options:
1) Keep the HW ESC & motor mentioned above.
2) Keep the HW motor, but swap the ESC for an RX8 (which I'm already familiar with, including the programming, as I'm running all Tekin in my Rustler 4x4).
3) Swap the HW ESC & motor for all Tekin (RX8 & (probably) Pro4 4000kV).

The HW motor is faster/more-efficient than the Tekin motor, thus the Tekin ESC & HW motor combo would make sense...but, at the same time, the Tekin motor is smoother, thus the 'all Tekin' option makes sense. Of course, there's also the dilemma of keeping both "of the same brand", thus options 1&3 both make sense. Also, don't forget that I will (in the next 1-2 months) be picking up a 1900kV motor, to be used with whichever ESC I end up with, for use at other tracks with 4S. Finally, efficiency (HW) and smoothness (Tekin) are both highly important...but, is one more important than the other?

This is my first 8th scale. I'm going to run a Protek servo, which one do you all like?

Thanks. I had the 170TBL on my list, i appreciate it.

You need to do a little dremel work for the 170sbl servo.
