Thanks to the experience gained over the years, I have been able to experiment all this allowed me to refine more and more the technique of designing and making the molds, thus making my fans more and more efficient.
Driven by the passion to always get the best out of these EDFs, I decided to expand the fan range with this VF-250.
This new measurement standard of EDF wants to address a type of customer that does not only use it at the RC level but above all on VTOL aircraft and other special applications.
The design of this new EDF system is based on the accumulated technological know-how thanks to the realization of several prototypes tested and tested thoroughly in recent years.
The fan components are designed as accurately as possible by a company specializing in the CNC sector, for the construction of the metal parts in question is used aerospace aluminum 7075, in this way you can achieve maximum efficiency both in mechanical strength and weight. The fan is not composed of individually glued blades but is conceived in a carbon fiber unibody frame that is completed with the turned aluminum 7075 components. The choice of making 10 blades the fan proved to be the best compromise between static thrust and dynamic. The rotation speed has been deliberately kept low with a value that is around 18.000rpm.
Along with the fan, an air cooling system for the engine was also designed.
The motors are interchangeable according to customer needs.
This EDF has been tested with TP POWER TP100 and TP100L engines, giving a reliable and performing configuration. Numerous tests have been conducted during construction and simulation to achieve our goal of providing the highest levels of efficiency and quality.
Efficiency refers to the low electrical absorption converted into high static thrust and high jet speed, all this is possible thanks to the optimal static and dynamic balance and the rotation torque of the fan.
Engine operation outside the specifications listed may damage the battery, the battery or the controller (ESC).
It is important that the motor and the controller are set correctly as recommended by the manufacturers, in case
the warranty can be invalidated. We strongly recommend that you use a watts meter to test consumption when you
set a new configuration.
If the current output is higher than the specifications recommended by the factory, then it must be regulated by the controller (ESC). Settings more suitable can be selected via the controller (ESC) in the TIMING and THROTTLE CURVE items.
FOR YOUR SAFETY
Keep a safe distance between you and the fan during testing and operation as suction may occur of objects nearby. Do not approach your hands while the part rotating is in operation.
All units are made with precision and attention by Vasyfan.
Without the sale, the whole EDF group is assembled, carefully tested and checked in all rotating parts.
This new measurement standard of EDF wants to address a type of customer that does not only use it at the RC level but above all on VTOL aircraft and other special applications. Precisely for this reason I decided to also implement the counter-rotating version, which allows to cancel the rotation counter-torque.
