Had the mt 9916 for two days and already problems. Most likely from taking prop gaurd off and crashing a few times.

Whilst flying I noticed bad stability and a wobble in the front left propeller or gear unlike the rest. so i took it apart and accidentally unsoldered the front left motor and all three wires (black, white, and red from the green circuit board and had to resolder both the motor and 3 wires. All motors seem to be working but I cant figure out why the front left propellor is wobblying so bad. Also when I try to take off the qq tilts forward making it where it wont even take off anymore. Ive tried ajusting the trim but it doesnt help. If anyone knows what I can do without sending it to a shop let me know asap.
 
I would check for a bent motor shaft....One thing you could do is swap out a prop and see if it does the same thing..if it does id venture to say its a bent motor shaft and you jeed a new motor..just be sure to get the correct one for it..You have 2 clock wise and 2 counter clock wise motors...Usually the left front and right rear are clock wise. And counter clock wise for the the right front and left rear...Hope you get it figured out.
 
Im new to qqs but there is a litte pin/screw type thing that fits into each motor... I swapped it out with one of the other from a different motor and the problem went to the other motor.. Thanks for your reply though, I guess I can just order a new motor from ebay.

The propellors go by geared motors. There is a little screw/pen thing that fits into the other gear.(not the motor gear). I took the "broken" pen out of the gear that was wobblying and exchanged it to a different gear and the problem went to that gear instead.
