The designer of this got it right! An excellent well made product! Be warned however:- 1. The LiPo on mine had no labels for capacity/charge and safety, making it illegal in some countries as sold. 2. Its VERY fast in plane mode, its even quite quick in quad mode. The default rate settings give safe handling in plane mode IF YOU HAVE THE SPACE TO TURN!!!!! GEPRC 1100mAh 3S push fit securely into the battery bay perfectly. It is a shame that the box will not accept the plane once the tails are assembled. They won't stand up to constant removal, so I have modded the box to allow safe storage and transit. I bought after seeing and flying a friends JJRC version, they are both excellent buy one................................. (Only stickers differ)
I have had several, they are wonderful, they fly anywhere and the battery lasts more than 15 minutes of flight.
