Fournier RF-4 from ECOTOP


TOPMODEL faithfully reproduced René Fournier's mythical "Avion-Planeur" on a 50% scale for a unique flight experience!

Indeed, this RF-4 is not only scale in shapes but its pilotage is extremely close to that of the full size, soft, sweet. This is poetry!

We feel that scale down models are always flying too fast compared to the real ones, which is quite normal. But this Fournier flies at a really realistic speed, reinforced in this by the superb sound of the SAITO flat-twin four-stroke.

Very quickly, one transposes in the cockpit and launches "ears" and other lazy eights that wind up with lubricity. In the dives that last for a long time, you have fun piloting the glide in search of energy to link, in finesse, like the Skyhawks, to a loop or to a barrel roll.
