My first X4 107D (FPV) makes already fun enough. But I wanted one from the family Hubsan without camera. What you do not see in the pictures, is that the engines against the X4 FPV are smaller. Sure, because the bears still camera and a larger battery (380 mAh). The X4 weighs about 13g less than the X4 FPV and also has a smaller battery (240 mAh). With the small battery I came to about 6.5 min. Flight time, with the big battery to 8 min .. While the 380s battery fits in, but is not provided, because the securing tongue bends down arg. Even the 380s battery must be quite strong pure pressed. Certainly, the not provided, but still somehow fits.
My X4 I bought at AMAXRC.de without transmitter. The copter can fly with the transmitter from the X4 FPV and joyful as well as with the transmitter of the Nano-Quad from Revell. The purchase without transmitter was risk, but since he virtually does not have special features, it's all the same soup.
