WOW, bad press for Tunze Turbelle

[rvitko]

Nano Streams all are within reason, for the same reason the 6065 and 6085 are so close, low flow, sufficient area. The effect is the same however so 6025 on one extreme is underrated, 695 gph and it actually does about 750 and 6055 is slightly overrated, stated is 1450, actual is about 1320, but very close. There are no major discrepancies on the smaller pumps and every pump will improve as a result of this research.

It sounds like installing a 6305 propeller shroud would open up the front and simply cutting off every other fin on the back would take care of that side. I think I smell a mod coming.

Give us 6 months, you will see the progress, you will see the solution, if you have an existing pump, we will take care of it.

OK. Good to know. I hope the upgrade or fix is easy and doesn't requires the end users to pay another premium. Since the "problem" is with the pump themselves, the controller should still work as expected after the fix, correct?

 

[nanonubey]

I can't wait for the retro fit, I was already very happy with my 6105's and hope to buy two more very soon!

 

[Macca_75]

Will these new shrouds (or what the solution is) be readily available for customers outside of the US free of charge?

Also lets hope the timing isn't like the mythical 7096 firmware upgrade

BTW - even though I swapped from MP40's to 6105's and have read the report I wouldn't swap back.

I think the retro-fit is awesome, but when I had my streams in my 180, it was the flow I could see, not the numbers on the box that sold me.

 

[wicked reefer]

Why couldnt you just see how long it takes to fill a 55 gallon barrel, or 100 gallon tank, whatever, and then do a little math? I could have come up with more accurate numbers in my kitchen in about 10 min.

flow pumps don't work the same as return pumps.

I am glad that Tunze is fully commit to the fix and acknowledges there is room for improvement instead of going in a denial mode. This is the primary reason why I always choose to support Tunze and its products.

If nothing else, the fix will help future users to do planning more accordingly. I am looking forward to the fix and fully expect my existing 6105 will even be better in 6 months.

 

[chadfarmer]

its good to see tunze step up to the plate and a little more flow would be nice maybe 1 less pump in the old tank

 

[derek4real]

If the newer Stream 2 models are off, is it possible that the older style Streams are off too?

I am waiting for my older streams to kick the bucket so I can upgrade to the Stream 2 models.

Thanks in advance.

I know that, but a test jig could be made, especially in a lab setting.

I do truly feel bad for you guys about the bad press, as this may be detrimental to your success, and I never want to see any company in this hobby fail,

How are they failing when they have already came out and siad they are going to correct the problem and make sure customers are taken care of? It will not be detrimental to their success in any way....if anything, it will show they fully stand behind what they sell and their claims as well.

I estimated fuel rating of 30mpg and you only received 15mpgs? you wouldn't want the company to say "well we estimated wrong" right! one thing in this hobby seems to always hold true "you get what you pay for"

The car i own had estimated 30, and I get 20 if I am lucky...but I still enjoy the car. Don't you think that analogy would make more sense to this situation if the car manufacturer were to come around and add a more effcient engine in it?

Yes you do get what you pay for. I paid for Tunzes because of their flow, reliability, silence, and customer service. The flow was estimated wrong, but they stand behind what they sell. Tunze is a great company with arguably the best customer service in this hobby, here in America at least. So what is your point? The company has ackowledged the problem, and instead of denying it or saying tough crap, they are going to make good on it.

Is your only purpose in this thread to attack tunze as a vortech fan? Because it accomplishes nothing. Even if these Tunzes were 1/10th the flow advertised, the pros of them over the Vortech still make it far more favorable to me. Besides, they are going to address the problem. Vortech has had problems in the past, and they addressed them as well. Things happen, what makes a company great is what they do to correct it.

Things happen, what makes a company great is what they do to correct it.

This is the bottom line. Every company screws up at some point. How they correct the issue tells me more about the company than the screw up itself.

 

[ghstrider]

Roger, I have a pair of 6105s as you know. Is Tunze going to send out the retrofits or do we have to order them? Is Tunze going to charge for the retrofits?

And regardless of how much flow it puts out, I am a very happy Tunze customer and am confident Tunze will go above and beyond to make this right.

I know i am out of my depth here, but I have one suggestion when it comes to propellors...have your counterparts in Germany contact Ernest Zavarsky. He is the owner of MHZ Modelbau, one of the preeminent manufacturers of German model poweboats and engines. I've been into radio control model boats for many years. There are things that the top racers do to the props that we use to make each prop perform to it's maximum potential. I know this sounds crazy, but I'm not talking about toy boats from toys r us. I'm talking about gas powered boats costing thousands of dollars that run in excess of 70-80mph, no exaggeration. The serious racers know so much about tweaking props that I'm sure someone would be able to offer insight to the design of your props. For example, if you simply round the tips of each blade, you will direct more prop thrust straight back; pointed tips let more water escape off the tip, instead of straight back. There are dozens of shapes, tweaks, bends and cuts that can be made to a prop blade to acheive a desired result. It may very well be worth the effort to speak to someone that knows high speed model boat props in order to come up with a more effective design. I'm quote sure that tunze has some talented engineers working on props, but think about it. It's got to be very hard to tell whats going on from one design to another when the prop is stationary and you can't tell how fast it is pushing something. With our models and some simple gps gear and a stop watch a modeler can tell instantly if a tweak to his prop made the boat faster. By seeing the rooster tail you can tell if the thrust is narrow or wide.
Just my $.02...

Please read the entire release- we are fixing it, there will be a solution, but we need time to find the solution. Within 6 months, we will be at or very near the stated flow.

For that matter, the flow is pretty much all there, we tested fixing the shaft on one end and using no propeller housing at all, the flow goes up 20-35% depending on the model. The issue is restriction of the flow by the housing and not some major defect, it is solvable, but it requires redesigning the propeller housing and some tweaks to the propellers. This really is not a huge catastrophe, it is a set back, it stings, it sucks it happened, but we will come out better for this. Imagine if the flow you had from our pumps which you were already satisfied with increased 25-45%? Before this article, I have not seen one single complaint, not one single post, PM or email that the flow does not seem to be what we say, how many posts are there about how much stronger someones 6105 feels compared to there MP-40 or 6055 compared to an MP-10. I think if you step back and just look at this rationally, even go to a store that may have both running in displays, you will see that gph only is a very small part of the story of flow.

So when you do find the issue, are you going to replace all of the 'defective' units for customers no matter how old free of charge?

Everyone keeps asking what they are going to do, when first, tunze needs to decide how to fix the problem. Then they will know what it will take, and can come up with a plan and follow through.

Tunze has a superior customer service, and I doubt they will leave hundreds of thousands of people hanging.

As mentioned,there are no posts about people complaining that their tunze 6X05 pump doesn't put out! But, with the tests, people now want was advertised which is an ok thing to want, but I see a fix, and also have to turn down pumps 50% when they get 50% more flow!! I can see some whirlpool effects intanks in the future ..

Just relax, and wait more then 48 hours for a fix and answer....
They are working on it, and I stand behind that. I have no reason to not trust them.
