So what is the motor Watts rating? And is there a 5mm rotor option?

my guess is 1000 watts pretty easily. mine was doin 750 pretty easily on 2s with mild gearing. but i guess we will have to wait for an official answer..

I don't know if we've run the numbers on these yet, but I'm guessing they are ~400-450 watts continuous, and ~800-900 watts surge. Looking at the specs on a Neu 1509, it is rated at 500 continuous and 1000 surge. So I doubt a shorter and smaller diameter motor can handle more power. Pat may have some data to back this up, as I am just assuming based on the 1509 specs.

Plenty o power! Thanks for the info. The 750 I got was just a max surge for the run. Close to enough to a 1509 With better wires and a castle price! I would say that in order to reach 110% efficiency they would need some flames on the can though....

When you guys say "~400-450 watts continuous", what does that mean?

a) You can run them with enough load so that they are putting out 400-450 watts for "X" minutes [fill in "X"]

b) You can run them with enough load so that they are putting out 400-450 watts until you dump the typical 5000-6000 mAHr 2S LiPo battery that fits in a 1/10th scale RC car at which point the motor is almost toasted

c) If you had a 6 ounce miniature nuclear reactor that fit in an RC car and put out 8.4V at 65 amps and would run 2 years between refueling, you could run it at the max load of the reactor (figuring 85% efficiency on the motor), stopping only to lubricate the bearings if/when needed, until the reactor needed refueling 2 years from the date you started the test (anyone remember the IB Infineon PDF sheet (joke) from a few years ago?)

d) [you fill in this alternative]

I'm just trying to get a feel for how long "continuous" is supposed to mean and under what conditions of temperature and cooling/heat sinking.

Also, how long can it run at the "surge" rating?

Well since I am not a sponsored driver , when can we buy them and how much $ unless I can get sponsored LOL.

The answer is b, but with less motor heat... At the end of a 5000mah run, the motor should be at about 80C. Well within reasonable heat limits. Usually with a good setup, you should be able to run about 10000mah without putting the motor in any jeopardy...

Castle sent me a 1406-7700Kv to test Monday and decided to house it in my TF Funny Car. Was going to and test it this weekend, but work and rain kept me from following through. So the next chance I get will be at the Lonestar Nationals at Autorama 2010 in Houston. Will report to Patrick right after.



The best ET so far on this Funny Car has been 1.46 with 2-pole motors and I expect to see a lot of improvements there with the 1406-7700.

In case you're wondering, those are 8mm bullets on the ESC So far, they've helped me get a 1.320 pass in my TF Dragster.
