This is the current list in IMPBA See the battery prop speed control and motor combinations ???

I will stay my course!!!! The NAMBA list is the same way other than the illegal boat.

Clugh

T sport hydro is open LOL! see the motor inverter combinations

Clugh

T catamaran is open too. LOL!

Clugh

As well as T OB tunnel oval so you should come show them how well this runs The OB list is all castle and neu

Clugh

In sure they would love to see this on the back of a prather lap cat II in A IMPBA or NAMBA SAW or 2 Lap competition.

Ive always wonder what the cell count and weight is of such a boat. what batteries does it use and what is the runtime.

Clugh

Maybe ill put the SHORT! 824 kv 448 gram 13 kw pk 10S black kama on a real bevel geared lower drive unit and get my hands on a ML boatworks tunnel! since it will turn an 1818 @ 90 mph for 4 minute at only 153 AMPERES!. Its definitely more efficient than a scorpion! It also will make 2 ft/lbs at the 13 kw

Clugh

And I'm sure "POC" Bill Oxidean has no issue if you bring your 2 cell boats!

Clugh

All Novak baby.... you see what brands dominate the list.....in this ERA.

T tunnel and T sport hydro is open so mount the 41 series lehner outrunner in a tunnel or t sport hydro and show up anytime. Your friends Tyler Garrard reviewed it and suggested a TP instead and I know It is quite different that the 70 series torqstar

The long motors in an outboard dont make any sense to me when the outrunners are available.. They lower the boats Cg significantly. When has that never helped handling?

Clugh

The way you deal with the higher iron losses associated with higher pole counts is the winding. Theirs is antiquated and that is the point! The ABB hybrid wind will half the total losses of the machine and that's huge. You can also change the static torque output of the engine by changing the winding. I guess this is what they do not want American sailors to know.

The beautiful benefits of a 41 series elaborate features to improve efficiency can all be had in a traditional radial topology if you just change the winding!!! U also might wind up with higher efficiency because 93.5% is no benchmark esp for a marine motor. The in runners are greater than 95% so everythings fine with "Black karma".

Clugh

The hybrids work in two ways. One they attenuate leakage inductance and that lowers frequency driven loss. 2 The open ended wyes coils serially connected to the deltas act as embedded load reactors so they will handle changes in load much better than a motor without, They help with inductive spikes etc. This is industry proven the rc toy motors are nobodys to reject the established effectiveness of it all..

Clugh

If anyone in the world has valid proof and data that the motors don't work this way please post it here because I as well as the entire IEEE and 70 universities across the world certainly need to hear about it.

Besides my own professional background I have several Phd contacts in Germany and the Americas emails you may contact with your disputed data. so we can have a TECHNICAL discussion about it!

The best viscosity ferrofluid for hub motor cooling

Proven to dramatically cool down your direct drive hub motor

Increases power, range, efficiency, and longevity

Run more power through your motor without overheating

5 ml of Ferrofluid injected into a direct drive hub motor will effectively make your direct drive hub motor more efficient by making it run cooler.

The syringe will fit in holes as small as 2mm so that you can drill a small hole in your hub motor so you can ferro cool it, a five minute job that does not even require removing your hub from the bike.

The magnets inside your motor will ensure that the ferrofluid does not leak out of the hole you drilled ( a big problem with oil cooling hub motors which also works for cooling but can make messy)
This is the highest grade ferrofluid available and will last for years even in the most rugged riding conditions. The drawback to cheaper lower quality ferrofluid is they will have drastically lower life span. Ferro Tec APG 1110 has been proven to last in rugged riding conditions for a year or longer. We recommend that you add more ferrolfuid to your hub motor every 2 years to ensure maximum cooling efficiency.

We have provided it in a complete kit including a drill bit, and a self tapping screw.

Note that the safest way to add ferrofluid is to drill into your hub motor case, since the small aluminum shavings cannot hurt your hub motor.

We have found that taking the motor apart breaks the factory seals and ferrofluid leaking out of those factory seals will shorten the life of the ferrolfuid (estimate to be changed once a year).

Read this Electricbike-blog.com article for more information on the benefits of this wonder fluid.

Ferrofluid is the snake oil that really does get more power out of your direct drive motor for very little investment and just a bit of work.

This is really a big breakthrough in hub motor technology that has come about in the last year.

Get the best Ferrofluid available Ferro Tec AGG 1110 for a great price.

You can take apart your hub motor to apply, or more conveniently just drill a hole as small as 2mm and squirt inside.

5ml of fluid is enough for most hub motor, use 7ml if you are running a 3000w hub motor or larger.

Ferrofluid is as magnetic fluid that bonds to the stators of your direct drive motor which helps dissipate heat by transferring heat to the motor cover and make your motor run cooler.

This is the scientific grade name brand ferrofluid made by Ferro Tec.
Once your hub motor runs cooler it means its more efficient and more reliable, which means you can run more amps which means more power. This Ferrofluid does NOT make your DD motor more powerful, it only allows you to run more amps through the motor before it overheats and causes damage to the coils, hall sensors or phase wires.

People have been putting oil in their hub motors for years to increase cooling, since ferrofluid is magnetic it bonds to the stator, not only doing a better job of cooling the stator, but also will not leak out of the motor onto your nice carpeted floor (if you park your ebike inside)

I share one trick!! Thats it!

Clugh

Been there and done it a long time ago and the article is incorrect. The best viscosity would be based on the expected frequency of the motor if it were linear.

Clugh

With that you increase the thermal conductivity to the water cooled jacket by 400%!!! so are we serious about who brings you new ideas to go faster? this is just one so i will see you at the lake soon enough. Youll also use my ideas because you will have to!

the airgap is a huge insulator of heat! Now you've learned something about the machines.

They will have never seen an electric saw boat like her. Just you wait and see. That type of cooling on the electronics is going to change things significantly

I can walk the talk So now all you have to do is ask them whet there better cooling solutions are.

Clugh

Not only are the castles sealed they are finned so under a water jacket they run cooler than smooth cans!!! I purchased what I wanted after several comparisons at different points of performance metrics like these and feel they are a good choice for a drag boat. The 3040 Lehner would be an excellent motor choice for it but I dont want the music producer all up in my videos. So I signed the record deal with Castle creations instead. I want an easy life not a bunch of drama and unnecessary direction only given so if the boat does well they can take ownership of everything unique in it.

Clugh

For instance get rid of the silly one line cooling loop config on the castle ice and run cooling directly through all 4 tubes and out of the boat at once. You could even have a separate pickup for each tube . Thats alot of flow. Thats how you cool a SAW boat. I know excatly what im doing so dont worry about anything but ya title falling. The water pickups can be placed on the left side and add the bias to ofset the rudder your heart desires in my boat. It helps when a person is allowed to finish their build without post facto designers help.

I put hardware in the manufacturers suggested locations because that is where I can expect without doubt to see the performance the boat has shown me in view that made me buy it. Thats called a baseline and that is a good place to start from. Heavy hull and hardware modifications before seeing how it runs from the manufacturer first seems silly to me. I dont copy people i have my own way of doing things so that can be expected and accepted. For the most part im doing things my way. im not here for help only to show you what IM doing with MY boat. There is no issue because I have always been that way.

If you have a better mono you want to enter into IMPBA time trials that is fine you build it your way! But this is mine to fail or succeed..

The castle powered phil Thomas ss45 that lasted a nanosecond in the German classifieds was built buy me the same way. I started with phils recommended setup points. People know the boats they produce.
