I do not have a MQX, but many experienced flyers swear by them as a great trainer. I like my 3 axis stabilized SYMA X1 mini's. For ~$30 and they will bind with any 9X Tx. Mini's are by their size a little large for serious indoor flying, but they are good for orientation exercises indoors. They can handle wind up to 5 mph reasonably well with decent -EXPO settings. With the standard 350mAh battery I get ~ 6 minute flight times in normal operating weather. With my 600mAh batteries I get ~11 minute flight times in normal operating conditions.
