All right now i've had it !!!!!

[Gary]

After I painstakingly prepaired my SAW Hydro over this winter i smoked yet another Hydra 240. This time instead of it smoking on the freaking bench i actually made it to un unfrozen lake to make some test runs. The boat never made it past 75mph and i only made some slow test runs because it was hopping alittle. My Eagle Tree said temps never got past 90 degrees on motor and ESC and rpms below 40,000. My combo is a 1527 1D , Two 11.1 volt 40-80 c batteries and a M645 prop. Boat is a Miss Dominator 30" hull at around 7.5 lbs. Boat will run over 100mph in good water.What ESC should i buy,. Shulze shows a 40-160 and a 40-300 but at $850.00 Any ideas?? Im at the end of the rope and am running out of steam for this hobby.

Try running 6s2p instead of 6s1p. Your esc will like 80c constant a lot more than 40c, especially with that big Neu! Someone has a Kontronik Power Jazz in the swap shop right now. It is an hv esc, I heard they are excellent.

[domwilson]

How many amps were you pulling?

[Gary]

Idid not measure amps but i know that i was barely pulling anything since i didnt even push it at all. I never hooked up the amp side because i knew it woud be over the Eagle Trees limit so i didnt bother.Im starting to think that Castle has just gone down the toilet.

[Rumdog]

2160kv on 6s is pushing it with any esc! Especially when it's a 1527!

[Gary]

I know i will take some heat for this set up but its not like i was at full tilt with it. And besides....it used to last at least 2 dozen rus and i was fine with that.......i ecepted a failure by then. But this is insane!!! How do you think a 32-200 shulze would hold up? It has a 260amp rating.

Not even close to the rating a 1D can put on it. But its a good thought anyways. Way too many questions unanswered to give you any decent advice. Gary you already know the 1527 1D can chew thru most speedos. Spikes well in excess of 300 amps. And you said it was hopping. The worse case scenario. PM the RRR SAW guys like I do when on the edge. Your prop doesnt sound too aggressive but again you have not provided enough info.

Yea it was jumping alittle but again no where near full throttle. Just getting it down the end of the lake.

1/2 throttle will kill a ESC every time and it does not take long at all I run a 40.160 in all my HV SAW set ups.

[Gary]

What do you think of the 32-200 Randy? What boat do you run and what kind of speed?

I have seen the big esc once, it must be good.

My Lift Master 38 Top speed 98 MPH by a friend and the War Eagle 36 at my best at 81.1MPH average at the LA SAW's

I have ran faster on a GPS but I only realy count the SAW computer passes at this point.

Gary, I know I'll get ridiculed for this, but before spending up tp $ 850.00 on a speedy, consider this : Buy a Turnigy 180. Spec'd 180 continuous, 360 burst, 6S capable. Throw some more caps on the battery leads. Give it a try. $ 99.99 reg.;
$ 79.99 Gold member. If it blows, send it back to Hobby King & they should send you a new one. Then sell it & go Schulze. What'ya got to lose ?

The problem was clearly owner abuse far in excess of what the ESC can handle. First, the hopping is death on ESCs, the voltage spikes are well over 350 amps. This alone can kill it.

Then there is the woefully inadequate battery. That motor is a beast and will pull every bit of power out of a 1P setup - and then the ESC will puke. Castle says this is one of the main reasons for ESC failure.

And the part throttle running - terrible abuse on any SAW ESC. While not stated, if this was a 240LV then no wonder it puked. Rule number one for a SAW ESC - never run near the max voltage rating. The 240LV is a 4S controller for racing, nothing more.

The Schulze won't work. I ran the 1527/1D on 6S2P with a 40-160 in my SprintCat in LA, and when it worked I had passes well over 80. But...the Schulze software wouldn't handle that motor with its very low internal resistance, it would lose phase and shut down in the middle of a pass...that's why I didn't set a new record. The 40-160 came through just fine after lots of abuse, but it won't reliably make back-to-back passes with that motor. It does work great on "Y" wind Neus.

Gary, the fact you are running at half throttle is worst then having the ESC at wide open... see, the FETs hold the surplus power sent by the batteries, therefore heating up. If you run at WOT then there is no power that needs holding in the FETs therefore adding less heat to the ESC.

Jay what version software is in your 40.160?
I have two V16s here that don't have a problem with that motor, and Ken Haines runs that setup in P-mono.
I did have one that would not arm with a 1515-1D. I sent it back to Shultze, they checked it out, and added three more caps, and the problem was (is)solved.
