In den Niederlanden ist Brian van der Gouw gerade dabei eine neue Wettbewerbsklasse zu entwickeln und zu etablieren.
Es handelt sich dabei um elektrifiezierte F3K Modelle, damit man den athletischen Handlaunchstart umgehen kann, trotzdem aber die gleichen, bzw. ähnlich Flugaufgaben fliegen kann. Eine reizvolle Idee, wie ich finde und aufgrund der Aufgabenvielfalt etwas abwechslungsreicher als die F5J Klasse, bei der es ja nur um eine Aufgabe geht.

kann man bereits einiges zum Thema lesen.
Der Vorgabenkatalog ist schon ziemlich umfangreich.
Prinzipiell funktioniert die Teilnahme mit einem Snipe 2 Elektro von Mahmoudi beispielsweise.
Der erste Wettbewerb der Klasse F5K ist für den 12. oder 13.10.2019 Losser / Niederlande angesetzt.
It is called the Losser Open.
Bin schon gespannt, wie dieser erste F5K-Wettbewerb anlaufen wird.
Hier mal die Vorgaben zum Modell:
Plane restrictions:
• Max wingspan 1500 mm
• Minimum plane weight 225 gram
• Minimum wing load 12 gr/dm2 (surface area = wing area)
• Maximum weight 600 gram
• Maximum allowed motor power 125 Watt
• LIPO batteries with nominal voltage of 3.7 V only.
• Maximum voltage at full charge 3*4.2 = 12.6 V
• Radius of the nose must be a minimum of 5 mm in all orientations.
• Any number of control functions is permitted.
• All ballast must be carried internally and fastened securely within the airframe.
• Each competitor is allowed to use three model gliders in the contest. It is permissible
to change parts between these three model gliders. The competitor may change his
model gliders at any time as long as they conform to the specifications and are
operated on the assigned frequency. The organizer has to mark the three model
gliders and all interchangeable parts of each of the five model gliders. All spare
model gliders must stay outside the start and landing field and only one model is
permissible in the start and landing field to score a valid flight time. The previous
model must be removed before a replacement model may be launched.
• Only in order to ensure safe flying, receiver voltage and/or flightbattery voltage
and/or remote control link qualilty measurements may be used to asses the
condition of the plane.
• Use during the flight of any other measurements on the plane is not allowed.
• The use of any automatic flight control or stabilisation is not allowed.
• Any material is permitted

Nominal Launch Height (NLH):
Starting an F5K plane is very similar to starting an F3K DLG plane. Launches are sort and spectacular. Difference is the speed which is applied during start and end of the launch. At F3K the start speed is very high (leaving hand) and the end speed is low (flying speed DLG). At F5K the start speed is low (leaving hand with motor on) and the end speed is high. Every second the plane flies, the speed is increasing. Result is an additional “zoom” height after the stop of the motor due to the “kinetic energy”.
The motor stop is arranged by two parameters: the “Nominal Launch Height”and the “Motor time”. Both parameters can be set in an altitude device such as an Altis Nano from Aerobtec. Both height as motor time are announced by the Contest Director.
Launch and Landing area:
The Launch- and Landing area’s are defined using a 30 meter tape pinned around the center making a hexagon with an outer enclosing circle with a diameter of 10 meters, called the individual “Pilot’s Area”.
The distance between two Pilot Areas is 15 meter from center to center.
The width of the flying field (perpendicular to the wind direction) must be 15 meters times the number of pilot areas, and the length of the flying field (in the wind direction) will be 30 meters minimum.
Launch rules:
Any launch starts with the plane being on the ground in the pilot area
The altis is activated with the plane still on the ground to set the zero meter offset correct
The person who launches the plane must stand still just before the launch, standing on two feet placed parallel, holding the plane above the head, before making any movements to launch the plane. The motor needs to be running before releasing the plane. Not following any of these rules results in a penalty of 60 points.
A helper may launch the plane for the pilot
The maximum launch altitude and maximum motor run time is according the “Nominal Launch Height” specifications. See Nominal Launch Height table.
Exceeding the motor run time will result in an invalid flight.
Motor restarts within a flight after the initial climb are prohibited, and will result in an invalid flight
Any launch after the maximum number of flights is already achieved, results in a penalty of 60 points.
While retrieving the model, it is not permissible to fly it back to the start and landing field. It will be considered as a new launch, outside of the Pilot Area, and will result in an invalid flight.
The pilot must retrieve the plane in safe way, without obstructing other pilots that are starting or landing. A penalty of 60 points is given if the CD or official timer is of the opinion these rules are not respected.
Landing rules:
It is not permittedto catch a plane for a landing, all flights must conclude with a ground landing. This includes the landings between flights as well as the final landing of the last flight of the task. If a pilot or his helper touches the plane, the flight is assumed to continue until the plane has landed on the ground and has come to a complete stop, and a penalty of 60 points is given.
Each pilot-helper team will have one specific “Pilot Area” that he or she can move around in, but not go out of during the flight, unless the line of site cannot be maintained due to obstructions or other pilots. Not following this rule will result in a penalty of 60 points.
During the landingit is permitted for the pilot to stand outside the Launch- and Landings area. The pilots need to go back in the Launch / Landings area in case the plane catches a thermal during the landing and the plane thermals her way up.
At the end of each task the plane must land within the Pilot Area boundary.
Landing outside the Pilots Area but within the flying field results in a 10 points penalty per landing.
Landing outside the flying field will result in an invalid flight.
If any part of the plane is inside a boundary, it is considered to have landed inside the boundary.
If the plane has landed outside the Pilot Area assigned to the pilot, and needs to be picked up, the pilot or helper may only leave the landing area after the aircraft has landed. Not doing so will result in a penalty of 60 points.
An invalid flight scores zero points, apart from any penalties given.
All penalties are cumulative.
