Ｆ２Ｇ電動スピード競技

２００９　ＦＡＩで発表されマンタ！

いよいよ電動スピードが始まるのかな・・・
レギュは意味不明デンナ
とりあえずワケわかんない機体が出てこないように
翼面荷重と重量、翼面積で抑えこんだ？
英文もよくワガンネ！
どうせなら思い切った規格でワクワクさせて欲しかった・・・・
考えた人はアタマ硬そう・・・

Ｆ２Ａスピードをまんま電動化しても電池の重量だけが突出してしまい
電動のメリットが出ないと・・・・

実は、密かに？日本初の電動スピードを狙い

コレ買って、流用しようかと計画してましたが

金融危機の影響で頓挫しマンタ！

CLASS F2G - SPEED MODEL AIRCRAFT

4.J.1. Definition of a Speed Model Aircraft
Model aircraft in which the power is provided by an electric motor and in which lift is obtained by
aerodynamic forces acting on the supporting surfaces, which except for control surfaces remain fixed
in flight.
4.J.2 Characteristics of an Electric Speed Model Aircraft
a) Maximum voltage of power supply 42 volts off load.
b) Minimum total projected area 5.0dm2.
c) Maximum loading 100g/dm2.
d) Maximum weight 600g.
e) The model aircraft must take off from the ground.
f) The model aircraft must be fitted with a wheeled undercarriage for landing. Minimum wheel
diameter 25mm.
g) The maximum flight time must not exceed 3 minutes from take-off.

4.J.3. Diameter of Control Lines
a) Only two-line control is allowed, minimum control line diameter is 0,40 mm with a tolerance of
minus 0,011 mm.
b) The lines must be round in cross-section and may not have any liquid or coating material applied.
Solvent may be used for cleaning purposes only.
c) No intentional twisting and/or linking of the two lines together shall be permitted from the point of
exit of the model aircraft to the control handle. The lines shall be separated by at least 5 mm at
the point of exit from the model aircraft and at least 25 mm at the handle.
4.J.4. Length of Course
a) The measured distance covered by the model aircraft must be at least one kilometre.
b) The radius of the flight circle must be 17,69 m. ( 9 laps = 1 km ).
4.J.5. Line Tests
a) A line test shall be made before each attempt for an official flight.
b) The radius is measured from the axis of the pivot on the pylon, to the axis of the propeller. Where
two propellers are employed, the axis of symmetry is taken as the reference for measurement.
c) A load sufficient only to remove the slack from the lines shall be applied during the line length
check.
d) A load test shall be applied to the assembled control handle, lines and model aircraft equal to 50
times the weight of the model aircraft and this test shall be applied separately to the safety strap
when attached to the competitor's wrist.
e) In each case the pull shall be applied three (3) times, slowly increasing to maximum load and
releasing rapidly. The pull test should be made on the handle grip, not near the point of
attachment of the lines (see sketch in rule 4.1.7 ).
f) The diameter of the lines shall be checked at random distances on at least three points along the
length of each line.
g) A safety strap connecting the competitor's wrist to the control handle must be provided by the
competitor and used during all flights.
