Le poids dont la descente entraîne le Flyer en avant pèse 545 à 635 Kg selon la nécessité (d'après Pierre Lissargue dans Pégase [1]).
Le pylône mesure 6 m de hauteur. La course utile du poids doit être haute de 15/3 puisque ce poids agit sur les premiers 15 m du rail et que le palan qui est mû par ce même poids est un palan à 3 brins [2].
On voit ici le rail de 25 m. La traction du Flyer par le poids descendant dans le pylône n'intervient que dans les 15 premiers mètres du rail.
Ici sont les deux chariots qui servaient au transport du Flyer. Ils étaient glissés sous son aile inférieure, de chaque côté. On voit ces deux chariots sur cette image.
