Anyone actually running 6s through a hydra 120?

[shockerman80]

Im wondering if anyone has any actual experience running a hydra 120? What setups are you running? This is what im thinking.

2 1527 1.5d (1500kv)'s

6s1p 5000 25c lipos per motor.

octura 447 counter rotating

42" MTI cat.

2 hydra 120's

im running it on 4s right now and nothings getting warm speeds in the 40's.

I dont want to kill the hydras.

any help would be appreciated.

i run on 4s, have heard they dont fair to well on 6s i use mine in a drifter s with a hacker 50, i forgets the winds

Yes, I got two 1515 1.5Ys (same kv) for my 38" intruder cat. Will be trying 5S to assure temps then goal is 6S, x442 props. Will post in my intruder thread once I have some data. Let us know how your works out. 5S should be no sweat. 6S??? lets make some data!

when are you letting it fly?

There is still risk running the LV Hydras on 6S. The 1527/1.5D is a hot motor, capable of pulling a lot more amps than the little 1515/1.5Y will. I'd wait a few weeks before claiming success with any setup, you may not hit the vulnerability limit until the combo has been run awhile. ESCs can collect damage cummulatively and may not fail for a number of runs after the initial damage occurs. This combo may work okay - I'm just spreading a word of caution.

Perhaps the largest risk with running at the voltage limit of the ESC - besides the higher wattage and resulting heat - is the current generated durring slowdown. On large fast boats the prop will spin the the motor turning it into a generator when you come off the throttle. Sometimes this back-generated voltage exceeds the rating of the ESC - and

ok any ideas on speed controllers then??? im trying not to run 500 dollar controllers if possible.

If your taking the precaution that Fluid mentioned then you may not be able to get away with ESC's under the 500 dollar range. The only controller I know of that will definitely handle the 6s would be the hydra 240HV. You may need to run slightly cooler motors like the 1515.

You could probably use two Castle Creations Mamba Max controllers. These are fan cooled and run using 6s power in monster trucks. Steve sells these.http://www.offshoreelectrics.com/pro...-mamba-Monster

CC ESC claims it's max input at 6s which is the same as the Hydra 120. Only two differences that I can see with the two. The CC ESC still provides BEC capability While the Hydra does not, and the Hydra IS water cooled as the CC ESC is not and requires a cooling plate. Overall I would use the CC ESC as a water cooling plate is cheap and it does provide a BEC circuit so if you do want it, it's there to use.

You must be joking

Adrian, I doubt he is joking. We are trying out our ideas in the virtual no smoke no cost world. please help us out with some constructive clarification on your comment.

he says (I dont want to kill the hydras) my answer is: you must be joking,I would not run 6s on a hydra 120

[shockerman80]

no im serious i have the bec disabled on the speed controllers. im using monster motors with next to no load on them 447s for a 1500 kv 1527.

[shockerman80]

im thinking it maybe wise to sell the castles and buy either the 7s rated ettis with cap boards . or something else. any suggestions?
