E-XTRA pattern kit from Laser Models
The Xtra is developed by Dennis van der Tooren, a Dutch F3A pilot. If you go to dutch competitions you will see many of the large Xtra's.
Based on the succes of the large Xtra , a Xtra-60 is developed (there is also a Xtra-40).
I have seen the quality of the laser-cut parts and it's great, also the model itself flies as a larger plane. at my club a guy is flying with a saita-100 in it. Great plane to practice or compete.
