Please do a review. Dai

I did not sure when it will go live, if at all.

dai phan,

I have not received my replacement ESC yet. According to Andrew they are waiting for Bancroft for replacements. Andrew believes they will ship it by the end of the week. I will keep you posted. I also, gave this boat a 2 star rating.

Please do a review. Dai

I can confirm that the factory has been closed for several days due to the seven day China National Holiday (basically their July 4th long weekend), but that replacement components were shipped by Air to our US Warehouse to fulfill the handful of service tickets the CS Team received. Those will be shipped out to customers as soon as they arrive and you'll be notified in your respective Service Tickets via your respective Motion RC CS technician. Contact them for any specific questions, especially if the delivery address is different from what was entered for the boat's original order.

The factory has been producing these boats for many years, so we're especially grateful for everyone's support as we elevate the production level to a consistent, modern standard. Hundreds are already out there recently, and we look ahead to continue moving forward. Tips about instruction manual improvements, requests for different finish levels, and other feedback are all valuable and we carefully consider everything.

Thanks all!

I am now waiting for MRC to provide me a new ESC. I agree since they used a marine ESC it should be water cooled. That is the way they were designed. Otherwise, they should have installed an air cooled ESC. At least I know how to correct that with very little effort.

So it is the same ESC and you have to do a mod yourself ? If the problem is due to poor design they should take the boat back, give you credit toward a redesigned boat. Dai

pdansalvish,
You mention that you are awaiting a new ESC from MRC, is this directly from them or is Motion RC involved. I wrote to Andrew of Motion RC tech support on Friday,but have not heard anything yet
Thanks for your time.

Please do a review on this boat so others do not have to go through what you are going through now. Dai

Have not purchased yet. At this point, I am an interested bystander and a possible future customer.

I have to say I was surprised to see that MRC had a water cooled ESC in there, with no water flow to cool it. That is the worst case possible, worse than an air cooled ESC without enough cooling flow.

My earlier proposed temp fix incorrectly assumed that the ESCs were air cooled and simply needed a little more airflow.

Aside from the testing we conduct alongside the factory's own, we always welcome the individual experiences of each of our customer family around the world. The more information, the better. Where things are great, it is nice to hear it. Where things aren't great, it is essential to hear from you where, when, and how, so we can uncover why, and fix it. Such is the cooperative relationship of transparency and attentiveness that we hope by now our customers expect of Motion RC. We live for this stuff.



Thanks all

Thank you Alpha for the thoughtful repsonse. I hope MRC can work out these issues. Many of us spent hundreds of dollars on the products that do not deliver. You can understand our frustration. Dai

Egghead, I'd wait 6 to 8 months to order, if you order. Like a new model car, it takes awhile to work the bugs out and get things working as they should. Currently these boats are a crap fest, and these lack of chiming in by MRC staff, who must be monitoring, makes one think they got the money, and don't give a sh!t. Crap electronics, which MRC can specify the specs on, or lack of cooling these things are all look, but crap real world engineering.

[dai phan]

RSRN,

Not sure a fan will help much. None of us have been able to run the boats much to see if the ESC is heating up. A 14 second run is insufficient to see if the motor is heating up. The problem is bad electronics and poor design. Considering what Rascal76 and southernmd_man have been stating these are marine ESC that need water to work. In my opinion with my 14 second run I doubt water would have even made it to the esc. I am at the point of considering sending my boat back for a refund. Spending $600 for a radio control boat that does not work is crap. I am heading to the campground for the weekend to think about my next step.

You have 30 day warranty period. I am filing a ticket on my Yamato issue (ESC). Dai

pdansalvish,
Once again thank you for your time to give me a very detailed explanation to my questions. I will be ordering the cell checker and the watt meter. Any thoughts about the cooling fan.Again thanks for your insight.

I was a mechanical engineer for 45 years. I designed electric motors and generators ( the mechanical aspects) for a good portion of that time. Big ones for wind turbines and Navy ships.
Bottom line is an electrical component that was deigned to be water cooled should be water cooled. It just wasn't deigned for air cooling. Yes maybe you can get away with it if the load is light enough, but it's not the correct installation for this component.
I am adding water cooling to mine. It should be an easy upgrade. I'll post images of what I do. The parts should be here tomorrow.
Check out a website called Zippkits https://zippkits.com/index.php?main_page=index&cPath=9 The first two components and some tubing are all you need. Lees that $10.00 in parts. and drill two holes.

Yes we shouldn't have to do this but I really like this boat so I am gong forward with it.

Here's a short video of the one and only test run. The next time around it quit.

I really like this boat and on my " MUST BUY" list. But really it leaves a bad taste in my mouth that you have to do this. MRC should do something about this. Dai

I have been looking at the Spec on MotionRC for the PT boat and they are quoting ESC 80A. fitted in this boat. Has the factory changed the Spec on this boat and not told MotionRC. changed motors , batterys, Esc, some factorys in China put the best equipment into goods for valuation they then deliver goods with lower price equipment.

Not sure if that is the case but I will be contacting MRC on the ESC issue of the Yamato. Dai

[Egghead]

I pulled the speed control out of the PT to get a look at it.
Looking at the jumpers it looks like they are in the wrong positions! (At least to me!)

The top jumper is set to the right. The diagram shows that it should be the left for LiPo batteries.
I am correct on that?
The bottom one is to the right in the "RC" position.
The left position is for "ESC"
I'm not sure which is correct for the bottom one.
If I was setting this up from scratch I would have picked the ESC position.

Can someone check this for me?

Thanks

pdansalvish,
Once again thank you for your time to give me a very detailed explanation to my questions. I will be ordering the cell checker and the watt meter. Any thoughts about the cooling fan.Again thanks for your insight.

[pdansalvish]

RSRN,

The reason I did my tests was to make sure the amount of AMPS being pulled did not exceed the rating listed. If more AMPS are being pulled then the ESC is rated will cause the ESC to burn up. Since you stated you ran your 3 motor's for 14 minutes at full throttle. I would take a good stab that your ESC is up to snuff. (I would still do a check just to make sure.) Now you did state after 14 minutes your motors stopped and after waiting a while they were active for a few seconds. Again this makes sense. The ESC has a built in protective system to prevent you from running the Lipo batteries voltage level to low. Lipo batteries should never be discharged below 3.6 volts per cell (optimum they should be no lower than 3.7 per cell). When the ESC recognizes a certain voltage level it prevents the motors for running. However, the rudders should have been working. This is where you should have a Lipo Cell checker and balancer (then run about $10.00). You plug the white balance plug into the checker. My plan for running the boat was to run it around for about 7-8 minutes. Bring the boat back to shore and use the cell checker. Depending on the cell voltages I would either take the boat out for a few more minutes or bring it in and recharge the battery. After a number of runs with cell checking I will be able to know how long I could run the boat comfortably. I would then set a timer on phone to remind me to bring the back to shore. This is where multiple batteries come in handy.

Hey pdansalvish,
Thanks for the update on the watt meter, so when I get this and the results are the same/similar to your,whats the recourse. I read something from tab 28682 that installing a small cooling fan attacthed to the heat sink would help lower the temp, run bt a seperate battery. I feel that someone MRC/Motion RC should be stepping up with a mod kit that would be available to all purchasers of this boat. Any thoughts out there.

I am waiting to see what MRC has to say about this. So far nothing. Dai
