I'm running an 2400XL (for now) and will be running 22.2v (LiPo), possibly 8000mah. I wanted an oversized controller to help w/ current handling and heat dissipation for long :30 minute mains at the track where I run. Its a large track btw w/ lots of opportunity to "open it up" if you can handle the speed.

I'd rather supersize something like the speed control and not have to worry about it being to small too handle the load.

you've seen my earlier reply?

No offense taken, just want to understand.

I measured voltage w/ the voltmeter... w/ one 7 cell battery pack connected I measured 8.x volts across those two leads (see pic) which means that if I hook up the second battery to that lead I will be putting a battery (w/o resistance) on an already complete circuit.

This would quickly overheat the circuit and destroy something (the batteries first, I presume). Is that correct?


btw, are you saying the sparcs are "ok" and "normal?"

it is normal that you measure the voltage there, though it is completely unlogical to measure there.

Take a cappacitor and put it in serie with the pack. you will see that you measure the 8.X volts too

the sparcs are completely standard and normal and ok too. any controller with a capacitor will 'suffer' this problem. (even my mamba mini controller does it)

Thank you, that's the answer I was lookin' for.

Isnt it just a matter of treating the two wires as one in the 18120? Thats what ive done but I havent got a chance to turn on the controller yet...... thats it right?

Exactly.
p.s.- I have your 9920 controller back, Luis.

Once I got over the idea that it arcs a bit when I plug it in the rest of the installation was easy enough. Took me one try to program the controller...and I got lucky w/ the motor wiring, didn't have to switch a couple wires.


I should be ready for a test run tomorrow night.

Thx for all the input (even the you don't have a clue comments).

Yeah, there seems to be a strong desire for a company like Novak to step up and create a line of high output motors and esc's like lehner, hacker, schulze, bk, etc... and only because Novak has a good reputation for service and support.

btw, looks like something from them is around the corner -> http://www.teamnovak.com/products/br...tem/index.html



With regards to the language barrier, even though many folks around the world speak English as a second (or third or forth!) language there are still idiosyncrasies in the language that unless you speak it frequently w/ an English only person some of the expressions and intent are lost in the translation (both ways). So I give them credit for dealing w/ me in English at all. :)

And I haven't even mentioned the cultural differences!

If Novak delivers a powerful (read competative) system for the e-maxx and other brushless MT's they'll definately take a large portion of the American market from the leading brushless/esc manufacturers.

I don't mean to hijack the thread, but I wanted to comment on your mention of the new Novak brushless. We had someone at my local track who was testing that new brushless for Novak about two months ago. He had it in a 1/10th pan car with 4 cells. This setup was outrageously fast. The car moved down the 76' straight in the blink of an eye. Not that a 1/10th pan car on 4 cells is going to put a strain on any proper brushless system, but it's also worth noting that after 15 solid racing minutes the motor was warm and the ESC was barely warmer than room temperature. I don't know which of the two new motors was in it, but it was indeed one of the new ones.
Just thought I'd throw that in. :)
