ZTW Seal 300a ESC, Who is using it ?

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

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.

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

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:Attachment 161624

Sweet!

No pressure Kent :hug1:

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

Omg!!!

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

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

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:

Look what rolled up today

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

same spec as previous ones then?

How can you tell ?

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.

Cool, i hope i have no issues

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

Very good!

Nice first run!

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

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
