ZTW Seal 300a ESC, Who is using it ?

[Speedfreek]

Is anyone using these ?
If so what do you think ?

[Prodrvr]

I'm on the fence about trying them...not enough of them out there that I see. And I need two, so that's a big roll of the dice.

[Speedfreek]

Looks like I will be the Guinea pig, I have two coming for my Mystic 138 ....

[Prodrvr]

Cool! When do you think you'll start using them?

[Speedfreek]

Cool! When do you think you'll start using them?

I should have them in no more then two weeks and just waiting for Kent to polish the boat ......:thumbup:
If it is what it says it is on paper it should be awesome 300A & 1000A :hornets_nest:161624

[Prodrvr]

Sweet!

[Speedfreek]

No pressure Kent :hug1:

[robw]

Hope it's better than the 300amp car version, ordered 3, 1 caught fire on 8s after about 10 yards, 2nd one went better for a while on 8s and 12s, then went "pop" on 12s when I connected batteries though it had been playing up before, slowing down on it's own, not being able to switch esc off via switch so had to disconnect battery to switch off, all this info sent to ZTW, 3rd I didn't bother, sent all 3 back to ZTW along with motor at their request, waiting for their response

[Prodrvr]

Omg!!!

[fweasel]

Good thing you've got a 138 hull to install them in. Those 300's are massive.

[Speedfreek]

Holly Crap :crying:

I will have 30 days to drive them like i stolen it and any problems, i will get them exchanged......

You're gonna have to do just that! If they're gonna let go, they'll let go right away.

[Speedfreek]

When I ordered them they where out, and they were about to do another run of them, so I hope they have changed the alleged weak spot in them and have it sorted out. Fingers crossed
But the boat ESC,s are definitely different then the car ones.
OSE Here sell them,it would be nice if someone chimed in to let us know if there having any issues with them !.
I will see hay :popcorn2:

[Speedfreek]

Look what rolled up today

[robw]

are they updated versions or same stock? ztw received my esc/motor, they asked what kv the 5860 was as there were no markings on it, I also told them it's a 6 pole motor, they were looking at the problem last week, on holiday next week and testing it next week, I want the updated version..... when it comes out

These are straight from ZTW they were just made, there was no stock before so ?

same spec as previous ones then?

[Speedfreek]

How can you tell ?

[robw]

sorry, I thought they were updating the 300 amp esc's I know they are doing another "version for car" from what ZTW mentioned, could be just "hearsay" on the boat esc, least you have them and can try them for yourself.

I have a post on my rc boat fb page from Peter Liao showing the redesigned 200A marine esc. I asked about a redesign on the 300A and his answer was "it's still under design, would appreciate any input". That's all I have.

[Speedfreek]

Finally my Mystic was ready enough to have a test run on the weekend with Kent (CCFP)
Good news is on 7s the ZTW didn't release the magic smoke within lol, here is a link to it, nothing fancy just a quick test.
We did see some water in it at the end which i have located the culprit and sealed it up.
I am definitely no expert on ESC's but it is smooth on the triger and was just warm to tuch, the batteries were at 3.8v storage at the end of this run. And yes they are a big ass ESC, size wise

[Prodrvr]

Very good!

[fweasel]

Nice first run!

[robw]

So far so good:smile: didn't know you were using a tp motor, not a good combo, hopefully all will be ok with marine version you have

[Speedfreek]

What's wrong with the TP motors ?

[Speedfreek]

Nice first run!

Thanks ,it came back In one piece :laugh:

[Speedfreek]

Thanks, ok for a first run :biggrin:

[robw]

Hello Rob,

After some tests, we found our 300A ESC can not compatible well with TP motor.
The current reached 30A with unload when we tested..

We will upgrade the firmware of the ESC and will make it compatible. That will take 2~3 weeks.

Best regards,
Peter Liao
that's one of the emails I received, they also had to modify the esc for some reason, 6 poles being one of the problems, they only tested 4 pole motors, I asked if the marine version was compatible with the tp motors, (as I was interested in one) answer was they "think so" as a few people are using them, tp motors are great, I use a few of the 58 series, fair play to ztw for making improvements, least they are trying, unlike mgm who told me to buy a lehner

[Speedfreek]

O ok , when they eventually do it I can download it to the ESC.:beerchug:

[Speedfreek]

Did a GPS run with some CNC props lol on 7S and got 88.5 mph.
Next run will be 12S And with some decent props that I got from Chris, should be good :roflol:

[srislash]

Go man go!! Glad to hear good things on the ZTW.

Haha, my pond has an annoying curl to run into too. I need to find a lake with a ‘point’ to run off of.
That is a nice spot to run though. Looks like it’s long too.

Ooo yea it's about 1 kilometer long and 250 meters wide approx, the downside is that it's salt water so I bring 5 litres of fresh water to wash down and flush the setup as soon as I am finished.

[srislash]

Ahh, saltwater. I have not contended with that as of yet. Keep her clean. Thought I heard rumour of Boats being faster on saltwater. Difference in hard and soft water too. Just rolled off the top of my head this morning, haha

[Speedfreek]

I suppose it would be, thicker soup so to speak :laugh:

[Speedfreek]

What's the word on that 1 or 2 Mile an hour difference?

[martin]

Less prop slip on salt water & hull is more buoyant as well, cant say in terms actual speed difference as i have never checked speed with a gps on salt v fresh water. I run mainly on salt water, when we used to take our same boats & props & ran on fresh water the boats always appeared to be revving higher but also looked to be slightly slower.

I agree totally, my first run In fresh water seemed more prop slip compared to salt water running

ZTW has the worst customer support. I went to there website to update my ZTW Geico programmer and it locked up the programmer. Then I contacted them to see if they could help me and got the response to contact the place I bought the programme from. I told them it worked fine untill I update the firmware and they did not respond for a few days. I contacted them again and gave me a big FO.... I have 3 ESCs and the 2 programmers I typed to update no longer work. I would go with anybody else but them. Never had customer support like that. Rude the whole time.

[LibertyMKiii]

Any new runs with the ZTW 300a? Do they have reverse? I saw it has a brake function...

[Speedfreek]

No new runs, its been either to hot 42 degrees Celsius or very windy, its ready to go on 12s and i have three props to try :tape:
Yes there is reverse.
From memory yes it does i turned it off, don't ask me why you would need brakes :confused1:

Im going to get one for a speed run RC road car so brakes is a good thing. Just need to get a small pump to circulate some ice water through the ESC.

I use the Castle XLX for speed runs cars it's got data login and it's just awesome I have run 144 mph with it no sweat :thumbup:
My personal opinion, I wouldn't use the ZTW in a car ....

Update run 12s

https://youtu.be/k0IHCXAY8B0

Let me know, what you think happened to the shaft :confused1:

[srislash]

Well I’m not sure but it sounded like a prop came out of the water mid run. Unless that was the prop coming off, but the rest of the run did not sound like or exhibit a sign of only one prop working. They usually take a dive right or left when you lose a prop (or worse). Perhaps it let go when you let off?

Hmmmmmm looks that way hay

[srislash]

I’ve had a few bad things happen from letting off. Once one ESC still had the brake set to on, OOPS!! Lol
Are you going to gat another Andy prop? 108 is real good!!

[srislash]

So what KV or more importantly what rpm do you figure you are running. I’m just curious as I also have a set of AB 447’s on my HPR 115. I haven’t given her the coals yet.

Lol, that was on loan those props :doh:, I have a custom set from dashboata to try, it's a scary looking prop lol.
Yea 108 is fast but she has more in here, the motors and ESC were luke warm.

Saw your recent videos of the 119mph runs. First off congratulations on the speed and being Australia's fastest Catamaran!
Any plans to move up to 14s?
Still liking the ZTW ESCs?

Lol Thanks.
After checking it's the fastest rc boat period in Australia to my surprise lol , not sure yet if to up the voltage or props still thinking about it.
ZTW ESCs working flawlessly so far , knock on wood .:Praying:

There is no data logging with the ZTW 300 is there ?

Which ESC would you think is the strongest the Swordfish 300 or the ZTW 300?

I am sure others will chime in but I have not heard good things about the new SF , the old ones are good.
ZTW of mine is working as it should.

Thanks for the reply I am running a F-41 Stryker Cat with a SSS 56-104 1000Kv motor on 8S2P oval racing I was wondering if the ZTW 300 would be strong enough. Right now I am finding out what the motor will handle in prop. I have a MGM 400-63-3 with a big cap bank But it is borrowed from another boat and I do ot want to have to take it out Saturday boat that night and install for Sunday boat.

It will be fine, i run mine on 12s in a Big Cat 138 , the ESC is BIG

[mxrb18]

Let me know how the ZTW holds up with the TP's! Looking at the same setup for my 138. TP 5660-1170kV and ZTW 300's

[mxrb18]

I wanna run the same setup! TP 5660-1170kV. Let me know how it fairs on 12S

[mxrb18]

was the firmware properly updated for the TP motors? Want to run a 5660 with the ZTW's but Id love to here back whether this problem got fixed or not

[Speedfreek]

It runs fine :thumbup1:

[Jrod2604]

Arw u using a BEC unit with the ZTW? Or a seperate receiver pack?

How many runs do you have on the setup in the Mystic so far?

The price of the ZTW 300A boat version has almost doubled during the last few month. Anybody knows why?

Like anything when new, it's cheap until it gets a name and then corporate greed kicks in :nono:

[plinse]

Well they try increased prices quite early then.

The controllers work well for you but there were no answers on solved software, ... yet. Over all it is quite mixed feedback when reading this thread.
And we all know how tricky our hobbie is. A little too much wind, a broken Shaft, ... and you easily loose weeks and months and don't run a boat at all... so some few boats are operated "100 runs in a season" but the bigger boats get the more often it is a small number of runs like 5-10 runs per season perhaps.

This is why I asked for the number of runs you have on the ESC.

On my F5B-ESC (hotliner application) I change the capacitors every season for example since I had ESC damages related to old capacitors and this is equivalent to just a few minutes operation time.
