and just think his regular customers like my self that run KO are getting advice from him... melvin is a bad ass in vintage lol....

big sean you need the stock motor manager... that does all the motors down to 10.5 turns....

Hi I was wondering if anyone has any thoughts on which 10.5 is the most compatible with the BMC.

1/10 TC carpet, rubber.

Perhaps I should try one. My Novak appears to have a lot of timing built in. The revs decrease after timing 5 at full retard, after timing 2 at full advance on the can. I assume its overtimed and the KO is preventing the problems arising from this.

I like the throttle response of the KO, and the fact the delivery can be tuned. So I would like to start with low can timing for good bottom end acceleration and to minimise current draw. I do not want the car to soften late in the run. Perhaps I can do this also with the drive frequency. Then hopefully I can use the electronic advance to increase to increase top speed, where the current draw and heat is less. This way I can have high top speed without gearing long and killing the battery.

Is it possible to use timing 6 without losing revs on the Trinity motor?

does anyone know if you can buy the KO fan by itself (without the heat sink) if so what is the part number.

I've got the worlds kit on mine, an ran it first time today (lightly on and off for less than 5 mins) just too check it, after the run found couple of the blades were broken and missing

Dont want too buy another worlds kit just for the fan, but i noticed that the KO fan has some sort of elec chip etc on it.
Is this a special heat sensative or speed sensative fan?? or can i use any other type of fan??
Just don't wanna damage my esc.

Cheers

every fan has a chip, that is the motor driver (it is a brushless motor).
(XXXfan that is sensitive to heat has three wires.XXX) KO fan is only two, so i conclude it does not have a temp sensor.
so you can use any 2.5x2.5cm fan on it.

edit:
oops i think i made a mistake.
fan that has additional sensor (usually an RPM sensor) should have more than 2 wires.
if there is an ESC with a heat sensitive cooling system, the temp sensor should be inside the ESC near the FET, not inside the fan.
so ESC fan with 2 wires like KO fan should be a standard fan.

this is correct, us that had problems with the ko fans are buying the much more 25x25 ultra high flow fans to use in its replacement and its a direct bolt on...

this is the fan we are usng: http://www.nexusracing.com/product_i...oducts_id=1854
