This is the version v1. The CG seams to be 80mm rear to the entrance bord of the wings (take in the juncion from wings and body), but, more test are needed to locate it with more precision.
The weight of the plastic parts is 333g. The weight in flight order is 570g and the wingspan is 600mm.
The model that I chose is "XRP / ChangeSun 11 Blades 50mm EDF + 4900Kv 3s Motor" (580g of thrust at 35A with 3s LiPo). For the battery I suggest a Lipo 3s 1000 mAh 45C
