The 128mm fan, the latest working novelty with Het, TP, LMT, Hacker or similar engines, it completes the series with a wide, complete and performing range.
These engines are indeed interchangeable with each other, always maintaining the highest levels of efficiency.
This particularity allows you to combine this fan with a your engine that you may already have.
For less experienced customers, our installation service is always available.
Use quality glue or adhesive tape to firmly fix the suction lip and cone before starting the motor, otherwise a strong draught of air pressure could detach the lip and cause damage. When the motor is mounted, attention must be paid to the length of the screws that are not too long so that they do not touch its winding or other components. This can cause serious damage to the motor and controller. It is very important to thicken the motor in 4 points with carbon splints on its length (in four or six points) so that it remains firmly stuck in the carbon stator.
Our EDFs, tested with the above mentioned engines, return reliable and performing configurations. Numerous tests have been carried out during construction and simulation to achieve our goal of providing the highest levels of efficiency and quality. By efficiency we mean the low electrical absorption transferred in high thrust and jet speed; this is made possible by the optimal balance of speed and torque. Our 10-blade rotor, thanks to its high efficiency despite high centrifugal force over long operating times, has been designed and manufactured in one block.
In order to guarantee greater strength and lower weight, the rotor is not composed of individually glued blades but a monobloc where everything is supported by an Ergal hub milled with high precision CNC machines
This new measurement standard from EDF wants to address a type of customer who not only uses it at RC level but especially on VTOL aircraft and other special applications. The design of this new EDF system is based on the technological know-how accumulated through the realization of numerous prototypes tested and thoroughly tested in recent years.
The components of the fan are designed as accurately as possible by a company specialized in the CNC sector, for the construction of the metal parts in question is used aerospace aluminum 7075, in this way it is possible to achieve maximum efficiency both in terms of mechanical strength and weight.
The fan does not consist of individually glued blades but is designed in a carbon fibre unibody frame that is completed with turned 7075 aluminium components.
The choice to create 10 blades for the fan proved to be the best compromise between static and dynamic thrust.
The rotation speed was deliberately kept low with a value of about 25,000 / 35,000 rpm. Together with the fan, an air cooling system for the motor was also designed.
The motors are interchangeable according to customer requirements.
Operation of the engine outside the specifications listed above can damage it or the battery and regulator. It is important that the motor and controller are set correct operating the engine outside of the specifications listed above may cause damage to the engine or the battery and regulator.
It is important that the engine and regulator are set correctly in the following cases otherwise the warranty can be voided. We strongly recommend using a watt meter to test performance when setting up a new system. If the current output is higher than the factory recommended specifications, then it must be adjusted by the controller (esc).
The TIMING and THROTTLE CURVE settings on the controller can help you set the appropriate levels.
