The wing is about ~1600mm
I've read some comments that these Modelfly planes would land a bit hot due to the weight and must say it's totally wrong.
Mine is probably heavier than the stock because I have a .70 fourstroke and a 1500mah ni-cad but the plane flies and lands like a trainer.
Landing in a light headwind was super slow and no faster than a normal 40 size balsa trainer. I did some super slow fly by's and the plan doesn't tip stall, it just keeps on trucking

The wing chorda is quite wide and the plane has lots of lift.
I really like this plane, it's heavy enough to penetrate some wind without being affected and the plastic design seem to be bullet proof, yet it flies good.
It's not a aerobatic performer and quite sluggish, but a perfect semi scale cruiser. I would highly recommend this plane as a trainer.
