Which config is "healthier" for a cc240 LV hydra ESC?

[BHChieftain]

I have read about issues with the cc240 LV Hydra above 4S. But, which config would be less stress on the cc hydra 240 (LV) ESC?

I *think* I know, but then there's Fluid lurking out there to set me straight



1) Neu 1515 1.5 Y (1500KV) on 5S1P (approx 28,000 rpm) on an x642 prop

or

2) Neu 1515 1y (2200KV) on 4S1P (approx 32,500 rpm) on whatever prop that would result in the same speed as config 1-- say an x440...

I would think option 1 would be easier on the ESC-- more voltage, less rpm. But not sure if there is something particular about the hydra 240 that would say a 4S config would be safer, even if higher rpm...

On a 45" hull or what?
That is what fluid may ask. Option 2 is a great proven setup and option 1 may have you propping up to get desired speed causing amp draw to rise.

2200 kv model then to a 642 or s215. You could even go to 445 if you don't have torque roll issues. Will be perfect on 4S. The 1500kv on 6S would be ok to a 640 prop. I run 6S on alot of boats with hydra lv sec's as long as amp draw is about half it's rated spec.

I can't really fit 6S in the hull-- so the 2 config choices I have are the ones I've laid out. I've run the neu 1500kv on 5S1P on x642 and even x645 a few times and like the speed and handeling, but not sure if I'm going to have an ESC meltdown... so my other option is to drop back down to 4S and use a 2200kv neu...

I would go with 4s and the 2200. Less battery weight on 4s and still more than enough motor to push a big prop if necessary. Either setup should be a breeze for the 240. A 180 amp cotroller would be adequate. I would run a parallel battery config too!

If the difference between the 2 configs isn't that much, I'll stick with the 1500KV motor since I have that one already!

You won't be happy with it. The hull won't like a big prop unless speeds in the low to mid 40's is ok? Too bad the motors are so pricey you could try both:).

Right now on the first config I'm getting low 50's on x645 prop, handling is ok. I'm more interested in reliability than all out speed...

I've read that given the choice it is easier on the ESC to feed it more voltage than more KVs for a target RPM... So if the first config is relatively safe on the ESC I'll try it for awhile... it's just that I've also read threads on cc240 issues on >4S...

Good to know. I am at the same dilemma with a 1527 I bought. I will run a low kv to higher voltage and smaller prop rather than lower voltage to bigger prop though.

Castle says to use packs over 9000mah when going over 4S. I run my 240lv's for the most part only on 4S because in some hulls its all I can fit. So the need to parallel packs is important. My TC31 currently is setup for 5S using a 240lv. I did add some extra caps but since the 5S2P setup is over 9000mah it doesnt bother me to use as is. The caps are added insurance but the key is to use the biggest packs you got.
