Something is not right in the setup. There's no reason the ZTW esc should not be working. You dont have any long motor mount screws or anything touching the windings or anything. Are you programming with a box or the transmitter? and is the transmitter setup for the full range of throttle?
Thank you,
Hubert

Everything seems to be connected just fine but I don't see an option to increase the throttle range on the transmitter. There's reverse, rates, end points, etc...My YouTube RC videos:

We had the end points and rates to 125% and everything in between. I already have the new ESC on the way and giving the Seal to Brian for him to noodle with. If it turns out it was a missed function/feature and the new one works great, I'll just sell it.My YouTube RC videos:

Aros I do have a question about the futaba rx settings on your throttle. Is it set up as an analog, digital, or SR mode? Have you checked that?
TIA,
Hubert

Hmm, great question! I'll have to check on that and get back to you.My YouTube RC videos:

You paid over 100 dollars for that servo? WOW....

I see TFH-N / Normal.
The servo wasn’t that expensive as I didn’t buy it from that website. It’s now discontinued but I heard it’s a good one.My YouTube RC videos:

So THIS happened.
I was trying to figure out what could possibly be wrong with my setup. I had a well known man in the RC hydro community solder me a setup that should have worked. He preferred an 8mm bullet setup (I prefer connectors that plug easily together which I am used to in model aircraft like EC5, XT90 etc). I didn’t like the multiple positive and negative wires all over the place be he insisted that was normal for hydros.
So I decided in my infinite wisdom to try again on my own and plug everything together and mess with the radio settings.
I noticed there were two leads coming out of the ESC. One for throttle and the other for SBUS. Since I am a Spektrum guy, I didn’t know much about SBUS other than I heard you can program everything with just that lead into the RX.
I plugged the SBUS lead into the SBUS port and thought that would be the difference.
Whoops.
When I went to plug the final cables together for series I heard a massive POP!! Followed by this giant bright circle of light the size of a volleyball so bright it looked like a welder’s arc.
I thought it was my last moment on earth. My fiance heard it all the way upstairs and came running. I was in a momentary state of shock. My fingers were burned and blackened.
It was a scary and humbling experience.
So I have ordered new 4S 6000 batts, and the new ESC of course. I have someone who is going to solder EC8s all the way around. No more stand alone wires. Every main connection will be a EC8 connector so I literally can’t screw up the wiring.
I had to discard one brand new 4S 6000 as the explosion literally bore holes into it. The other one seems to be fine. I checked the cells and there are no irregularities.
A scary experience to be sure. I will never again put myself in a situation where I am unsure of an electrical setup. I am lucky. It could have been much much worse of an outcome.

I'm sorry Todd I feel like its all my fault. The connector advice your friend is valid, EC5 and XTC90 really are on the small side considering a q hydro can pull and average of around 180 amperes around an oval. It also about which connector has the lower voltage drop across it. Amass 7mm or the Castle 6.5 or 8mm. You have to be careful with the bulk connectors from china and usa distributors or china because the economic side of a cheap connector probably uses copper cladded aluminum which will have a higher resistance than pure copper every time. I set my male & female plugs up in such a way that reverse polarity has to be intentional I always make the positive hooded female and the male negative let me show you about the EC8 which is good but the AMASS is better.
Sincerely
Hubert
