Here are the specs of the product :

The Ray X is produced in several material versions. It is produced mainly for the F5J and F3J category. In 2013 Mr. Vojtech Valenta senior won first place in the International F5J competition in England with Carbon Spread tow 3.8m version.

As a sport or competition model it has great flight characteristics, especially in flat field thermal conditions, but also preforms very well as a slope glider. The Ray X has a slim fuselage, with a 30mm spinner size for electric motors. The model is made with a wingspan of 3820mm and 4000mm and with X tail full floating elevator.
