Wissous 99

The first French Indoor meeting of the year was held in Wissous (91) on January, 3rd,1999.

Merging Free Flight and R/C Indoor enthusiasts, this meeting allowed fruitful exchanges between adepts in these two categories, so true it is that new RC Indoor fans can learn a lot from their FF seniors.

But, with no doubt, the chief attraction of the show was the presentation by three among the best French Indoor specialists (the Twisteuse team), Jean-Marie Piednoir, Gerard Jumelin and Jean-Yves Martin (from left to right on the picture) of what could be the lightest R/C Slowfly of the world (proportional FM radio), a 28 gramme R/C plane!

The king first! The Wizard of Oz, it is his name, effectively weighs 28 grammes (one ounce, where his name comes from!), with a 64 cm span and a wing load of 3,1 g/dm2 (1 oz/sq-foot).

The receiver, the speed controller and the two actuators are all home-made and weigh 5 grammes total. The motor (HS80 servo motor) weighs 2 grammes and is fed by two NiCd 50 mAh cells and a dc/dc converter (2,2V to 5,5V).

The FF models

All the FF models, peanuts, pistachios and a 1,8 gramme helicopter got tremendous applause. A lot can be learnt from FF technics and from the way they are trimmed or decorated. A lot of thanks to the author for this nice demonstration.

The other models

Among scale models, a Demoiselle and a Gee-Bee were presented. they both fly very well.

Jean-Michel Yvé and his Horten wing, Hortense.

Strange, but it flies!

The last Gerard's delirium.
"Lucy in the Sky".
And she flies!
