i had a few questions about your 65161 motor, in this picture there are 4 wires, in all the other pictures the 4th wire from the center of the motor is not there, you are also listing this motor for $500 when banggood is selling it for $350 and flipsky $450, there is nothing listed about a sensor wire and it says in your description “Flipsky Brushless Motor Sensorless Amphibious Fully Waterproof Motor” im just wondering what that wire is for since its not mentioned
the 4th wire is Hall sensor wire, now we do not have this version motor in stock. Just update the pictures and make the price more competitive, only $399.99 for the motor and you can use discount to spend less. Thanks for your reminding.
I’m afraid this is too complicated a task for you, you are only a businessman (not a designer, manufacturer). For example, how to determine the blade shape or the number of blades is rocket science. It’s also dependent on whether the propeller should achieve high efficiency (extend battery life), or high thrust (big weight rider), or high speed … or various trade-offs between all that. The same is true for the wing.
A possible solution is that you mediate contact between the manufacturer of the propeller in question and a hydrodynamics expert. The hydrodynamics expert can then very easily explain what changes need to be made to the propeller to suit the particular motor type.
I believe that there are currently an estimated 6 types of propellers in successful use among e-foil users around the world. The FR propeller is only one of them, and is probably the most expensive of them all. It is therefore not possible to answer which propeller would suit the most. I personally am interested in getting the propeller that will allow the greatest speed and longest cruise. However, these are two conflicting requirements, only two different propellers can meet them. So I need two different performance propeller types. Unfortunately, the current FR propeller type does not meet these requirements.
A possible solution is that you broker a contact between a Chinese propeller manufacturer. I can then provide him with all the necessary data to start producing propellers for e-foils with the highest pramaters in the world and at a favourable price.
Can you put me in touch with a Chinese propeller manufacturer? Yes or no?
This is just one of all the other examples of a forum member buying a relatively expensive motor (Flipsky 65161) and the propeller offered with it (suitable at best for a small fishing boat on the calm surface of a small pond:-). He subsequently finds he can’t use it, so he either puts it away or has to go through the sophisticated process of reducing the diameter of the blades by grinding them down. However, such a trimming process is always trial and error. As a result, sooner or later he has to buy a new propeller. And since his budget is also reduced, his first choice is this propeller https://www.custommotorsfrance.com/product/propeller-complete/ It is a propeller that is not only one of the six favorites (as I explain above), but originally designed to power the Fliteboard e-foil, which is considered the best in the world.
So the topic is about the same propeller that you are offering today (8 June 2021) on your e-shop and claiming that this propeller is an accessory “for Efol”.
It’s unbelievable, the topic “How would you trim down this metal prop?” was already created almost three years ago (November 10, 2018) and to this day not a single Chinese propeller manufacturer has shown interest to start producing the correct performance type propeller.
