Mini CP good for flying and much stable than Genius CP in 6-axis mode. But for beginners, the main motor is a little bid too strong. Suggest to use the Genius CP motor in the Mini CP. Sufficient power and the rotor is less damaging for beginners when flying indoor.
Compared with those online shops overseas, buying from TB is cheaper, reliable and fast delivery in my experience. Bought many parts from TB. Choose shops located in ShenZhen and you can enjoy next day delivery (i.e. order in the afternoon and received items next morning).
