Customer Reviews



Bonjour Mesdames et Messieurs,

Félicitations aux concepteurs et constructeurs de ce magnifique modèle qui semble être bien né pour de belles séances de vols !


love it

except no mention of where the CG is in the manual


This plane looks really nice, and has some nice scale touches like the jury struts and the nav lights. That's why it irks me so much to see the side windows as stickers. I realize it reduces model weight and complexity... but it makes a really good model look meh. I hope there is a version two of this plane that aims to improve of the scale appearance.
