The all new sport/3d jet is a masterpiece!! Designed by Italy’s Sebastiano Silvestri. Its 
design is based on a hawk aircraft. And then been improved further with aerodynamic 

ideas learned on other pattern models.it is a very lightweight and strong construction. 

This helps, as the flight speed rang is really impressive!! Designed to take an engine with 

100n of thrust, it is setup to be an ideal jet trainer BUT with a 220-250n turbine you have 

the ultimate 3d jet!!  

This will let you into a totally different flying experience!!
