Repair Hobbywing Seaking T180???

Is that a series of typos, or are you guys really talking about a m455 prop? Are you sure you don't mean a 445 or a 545? A 55 mm prop is huge for that boat with those rpm's........

It is M445 as I said "(SC 6S 4082 1800kv T180 M445)" I have a M545 for it as well.

I've had ESC's that stopped working & the only problem was the caps had gone open circuit. Replaced the caps & the ESC worked again.

Strut 1/8 inch above sponsons slightly negative angle.

The strut is even with the ride pads and as high as it will go with this prop. I will need to machine some clearance to raise higher. This strut is also massive. It could easily be bored for a 1/4 driveshaft and bushings. The walls so thick I was thinking of boring it for 3/16 sealed ball bearings. (Ball bearing O.D. larger than bushing O.D. for same I.D.) Thicker walled than any other 3/16 drive I have. So what I am saying is, at level with ride pads the centerline of the shaft is about the same as other struts set 1/16 to 1/8 above the ride pads.

If it was just the caps, I would have gotten a response from the ESC or a hellava spark on connection. The caps would have gone to a short or open. The caps charging is what causes the spark when connecting Lipos.

Not necessarily true. Blown caps normally cause an open and there would be nothing to charge so no spark. Replace with a couple cheap ones so you're only out a few bucks if it doesn't work.

True. And there wasn't a spark when I tried it again. An open cap would not prevent the ESC from reacting in some way. At least that's what I believe. Unless there is a analog circuit (R/C time constant) on the input necessary for operation. But that would be sensitive to changes in capacitance on the input. Which isn't the case.

Less of Might be worth buying a new e.s.c. so can get boat running right, so the boats not down and use the other one as a backup when u get it fixed. Just my 1.5 cents after taxes

You mean 1 cent after taxes!!!!!

I plugged a 6s pack in again. Got a normal cap charging spark. Hmmm. All caps look ok. Unplugged and checked with voltmeter, 24.1 volts. Caps charge and holding. No bleed off by ESC. No voltage on BEC output. Looks like something blew open circuit right at the input. There maybe a chance of fixing this. Maybe just a trace on PCB fried that can be repaired with a piece of wire. I'll dig in and keep you posted.
