Faster car

[sc302]

which do you think is better for a faster car? 6800kv on a 2s or 2800-3300 on a 3s? The 2800 maybe two teeth higher than stock on the 3300kv? Thoughts?

If this is for the 1/10 2wd or 4wd I would go with the 3300 on 3s. 6800kv is way too high kv. In something the size of the Ruckus you probably don't want to go much higher than 4000kv.
If this is for the 1/18 Ruckus, I would keep it brushed unless you are running the losi/vaterra diffs.

1/10th scale 4wd. 6800kv is what ecxrc has for a recommended upgrade to otherwise stock brushless trucks, which is why I asked.

Where does Ecx list a 6800kv motor as an upgrade? Last I checked they only had a 3300kv and 4000kv motor listed in the option parts.

Now I found it. I am not sure why they even list the 5800 and 6800kv motors, but running those in a truck this size would just be stupid. Voltage and gearing makes speed not the kv of a motor. Why do you think most 1/8th scale trucks run 2000kv or lower motors?
Like I stated before 3s on either the 3300kv or the 4000kv motor would be your best bet.

go to ecxrc.com

go to the "go fast" tab

select "1/10"

select "brushless"

scroll to bottom under "stage 4 performance"

see motor option. part number dyns1611

I don't know why they suggest that size motor...and I know, which is why I asked about a lower kv motor and a tooth change vs going to the 6800kv motor. It is strange that they suggest it, however I can only assume that they suggest it for some reason or another and it does make speed. Do you think they tested this or do you think that they just put it out there for the sake of putting it out there? Again, assumption is that they tested it. I could go the easy route and what has been documented, or I could go this route and hope that they did their r&d with this motor (little documentation on this motor or results using this motor).

I will probably go with what is in there or get a smaller kv motor with a larger battery being that is what seems to be the way everyone goes.

I think its just a generic upgrade list for the 1/10 scale vehicles. That motor would probably be fine in the Boost and Circuit as they are much lighter vehicles.
Just for reference, I'm running a 3100kv 3665 eBay blue can in my 2wd Ruckus on 3S and it has gobs of power. Truck will very easily flip on its lid backwards from a stop. It is currently down for repairs at the moment do to clipping a fence. http://www.ebay.com/itm/Original-3665-4Poles-3100KV-Brushless-Motor-for-RC-Car-Boat-Durable-NEWEST-G6Z7/162111620121?_trksid=p2047675.c100005.m1851&_trkparms=aid=222007&algo=SIC.MBE&ao=2&asc=38530&meid=912479a4b456441281f878592f810f2c&pid=100005&rk=2&rkt=6&sd=141711650326

yes, but they only make 4 stock brushless cars..which is what I would assume that they are gearing that parts list towards. Either way, skipping that specific motor.
