Anyone Into Unlimited Hydros?

[Elbee]

Aros, Whoa, not good. Can't say anything other than by your description, the ESC would be my first to start the triage. Good luck and don't give up, never give up. Best, LB

[Aros]

Too much invested my friend. Definitely not gonna give up. She will see the water again!

[Clugh]

I went for her second voyage last Saturday. Weather was stunning, the lake was basically glass. Couldn't ask for better conditions. I have an 8S series setup. Ran the first time with it perfectly fine. Plugged the first EC8 connector into the adapter, and when I went to plug the second battery's EC8 connector in, loud POP, flash, started to instantly burn, electrical smell, some smoke. I unplugged it as fast as I could. Slight damage to the finish (grrrrrr!!!!) from dripping aluminum or whatever the connectors are made of. Dinged my finger a bit trying to unplug as fast as I could. Blood on the hull...What a mess.

I just don't get it? On my first run, she got really waterlogged. I wonder if the ESC was compromised at all?

I'm going to bring it to my buddy who knows his stuff about electronics. Hopefully he can get it all figured out as I am not a big fan of having a $3,000 book end collecting dust.

It shouldn't have been because its waterproof and can run fully submerged.

Cheers
Hubert

Put your boat in the bathtub and see where the water gets in. You have to plug the auto bailers for this test. Just a suggestion that when you get the boat on step keep it there. If you on off on off the throttle you are asking for cooling trouble. It also gets alot wetter and possibly inside that way. If you have decided to run the boat now and don't want the 3000.00 book end go ahead and run her!

Crash it repair it or build another one. Thats scales and we love em remember

Id submit a warranty claim to castle but if u open the esc the warranty will probably be void.

Sincerely,
Hubert

Since then have you checked those battery voltages? If so what are they? You can do this yourself and must fully familiarize with the electronics if you are going to run the boat.

You also never logged so how do you know how many amps you are pulling truly? If I missed that please forgive me. Dont know if you sent the boat out yet but If it were me id take the esc and batteries out and make sure the hull is dry the do the tub test. After that do the most logical thing and see if you can get the warranty repair. Also did you reverse voltage by chance? Before you run the boat again please go through a test run of some arbitrary motor you have laying around and familiarize with esc setup and logging. You gotta do this brother... Yes its a bit time consuming but you have to know the number my guy.

Thanks
Hubert

There awesome but I’m kinda limited on finances

[Aros]

Everything I have checked Clugh has been in the clear. Voltage normal. Batteries, amperage, everything. Why would it be perfectly fine on the maiden and suddenly not be the second time around? I am using an excellent ESC, EXPENSIVE ESC...Aligned with the motor Kv...8S setup with HV connectors...Man, I give up. If this system doesn't work, what will?

I am taking it to a good friend of mine this weekend who knows his stuff far more than I ever will. If he can't get the system setup, nobody will.

At least she looks purdy in pictures! LOL!

Its absolutely beautiful. You'll get it together but if the ESC is gone castle will probably replace it but dont let the warranty time run out. Is the motor you using a delta or wye machine?

Well dang, Ma and Pa down in Hutch believe she is a looker fur shurr.

Sorry I don't even know what that means.

[f4u ausie]

Does look ABSOLUTELY INCREDABLE on the water... great shot.. ya have worked hard at it cant stop now

[Clugh]

Imagine the motor has 3 coil AB and C

In the delta the start and end of each coil are connected together and each union is a terminal for the speed control. in the Wye each phase coil A, B, and C ends share a common connection called the wyes pigtail and the starts of the coils make up the 3 termination to the speed control. Your motor should specify if it is indeed Wye or delta. "Y" or "D". If it is a delta machine make sur ethe ESC has the latest FW version.

Good to know, however I still have no clue which it is...Here's the link to it:

Ok. Let me do some digging.

Thank you

Thank you

It a 3.5 turn Y motor so you were good with or without the FW update but always use the latest. But still start the process for a warranty replacement on the ESC if it is damaged which it sounds like it is.

With the FE u really need to log to know where you are at, but if it let go on connection you may have gotten a defective inverter. Castle is pretty good about covering that.

Make sure the screws that hold the motor in place are not too long also. It they touch the windings you will have problems. Have your friend make sure none of the phases of the motor are damaged or shorted to the case.

TTYS

Roger that, thank you!

Hi Aros,
that is a very beautiful boat. Do you have any way of testing the ESC outside with another motor? A friend nearby or is there a model flying club nearby. I would first check the regulator to see if it is still alive. Then you can test the engine in the boat with just a few cells. If the engine is also alive, you can increase the number of cells and carry out your first trips. Are all the cells OK but test a slightly smaller propeller. If things don't get too hot and things are moving forward a bit, choose a larger prop. So that the boat can go onto the steps with the smaller prop, you can stick a ski under the propeller shaft, which acts like a sponson and supports the lift on the propeller. The boat then runs as a 3-point boat on the running surfaces and not yet with the buoyancy of the propeller. You can leave it like that too. The boat always runs very stable and has a defined position. Semi-submersible propellers are a bit wikey wackey, sometimes more, sometimes less submerged. They only run more stable when there is a lot of power and speed. So first test with a somewhat limited setup and then add more. Hubert, writes everything correctly and is very helpful to you.

Hi Aros,
Christian has held and shattered world records several times in some of the first real fast electric boats. He is a friend and engineering consultant for Lehner. He was running fast electrics before I was born and I'm 53. Alot of knowledge in setup of such things. Good advice that is absolutely free. You and others may want to write some of the key points . Not everything can you get from a book. I always store formulas and relevant links somewhere I can always go back and reference. Some of the older maritime engineering books in his possession are also hard to get your hands on.

Thank you very much! Excellent wisdom. I will absolutely look into that. My buddy was able to get everything working. Thankfully, the ESC is totally fine. He thinks that it was likely saved because of how fast I unplugged the connectors as soon as I saw the arc and POP. Even the batteries are completely fine. I lucked out. Se we swapped out the connector from the series adapter to the ESC from EC8s to QS8-S Anti Spark connectors, and walla! NO SPARK! Everything plugs in wonderfully, and works.

He also said I need to balance my prop. That's why it's so LOUD and the whole boat vibrates. So that is next on my list. Finally, I need to figure out how to set my throttle trim. As of now, if I barely touch the throttle it is FULL BLAST. Not the power curve I need.

It seems with all the help I've received both in this thread and from friends within my region both new and old, she's almost ready to enjoy on the regular. I can't thank all of you who have participated in this thread enough.

You need to let Brian Buass prepare your ABC props. Now that you are in the clear go ahead a pull the log data off the inverter. Goto castle and read through the process. If you need clarity LMK. Were here and got your back. CL also has the new castle so if either of you have questions I might be able to help. I have the XLX2 version. But I think you both should add some external capacitance for security.
