1.1M Cat setup help

[Brushless55]

they do draw allot of amps i blew a TURNIGY Sentilon100A HV on the second run on 6s brought an Etti 150 race blew the capacitors on it i had it replaced and had the capacitor module fitted to it and so far so good
on the KB45-08L 2300kv 4s would be the max i would run,and start with small props x442 or similar these motors are rated at over 3000 watts
I have to say that i do push these motors to their limit but then they are cheep to replace
i gave my boat a short run about one minutelast Sunday with my new Hyperion 5500mAh/35C batt and could really feel the difference in power we will see how the motor & Esc will cope with 3 minutes runs
what esc did you want to run in it?

Adrian

The rating of 3000 watts is on 10s I believe

If I decide to go with the HV ESC. I can up the voltage and choose a lower KV motor.
Same power, more volts, less amps. :)
What KV motor would I need at 9S A123 = ~28V ?

i did not say that they produce 3000 watts on 6s
The rating on these motors are
KB45 8XL :3528Watts @36V
KB45 8L:3439watts@36v
These ratings are totally over the top
We all know that a 10s pack fully charged will put out more then 37 volts
these motors are rated at 36v max so a 10s pack would fry this motor in 30 seconds or less I have a good friend that ran an 8L on 8s in a ducted fan jet the thing got that hot it melted the fan unit
I ran my lizard on 8s myself for less then a minute and the motor was so hot you could not touch it
My opinion 6S max and don't run them parallel I like these motors but lets not forget they are cheap

Forget the KB or Feigao at 9S, get yourself an A class motor

id agree, 9S you will need an A Grade motor...

I wouldn't run either a Fiegao or KB over 6s

[Brushless55]

What about this version?

[crabstick]

sorry i should re-phrase, I wouldnt run a Fiegao 540 series on over 6s

the 580 yes I would run on 6s

[Brushless55]

I wonder how much better the new 580s are over the 45s

[EPower]

The 580s are supposed to be a better motor but who knows, i haven’t seen any feedback so far on their performance

[Brushless55]

I wonder how one 580 would do in my Mean Machine?

I would say it would go great what are you running at the moment ?

I will be putting my SV27 motor and esc in it this weekend..

I know there is no substitute for horsepower but 580s in a SV27 that's a total overkill LOL
This is also a very nice motor

●Input voltage:DC11.1-22.2V 3-6cell Li-Po
●Max continuous current:70A/85A(60sec)
●Max output power:Approx. 1600W/2000W(60sec)
●KV value:1650KV
●Dimension:spindle 5x65x43.3mm
●Weight:Approx. 300g

i will run one of these when i kill my KB45

Adrian, I think Brushless55 was saying he is going to put the sv27 power plant in... not a 580 into a sv27

[Brushless55]

Yep a Mean Machine Cat..
That Align motor on 5s in my MM would be killer!
