About Us

These are the first bricks of our comprehenisve F5J Competition TimeKeeping system.

We are Marta, Sergio and Javier competition gliders enthusiasts. We have been largely involved in F5J contests since the formula was created.

We feel this F5J formula is the most enjoyable FAI formula with all the emotion of simultaneous launching and landing in the edge of time challenge. But it also brings logistic complications both for training and competition.


This is our  contribution for an easier, faster and more successfull F5J and model gliders adventure...
