Hi there,

On Saturday I landed (not crashed) my Syma X5C-1 slightly too quickly in some loose dirt. One rotor in particular picked up a lot of dirt mean that the exposed mechanisms underneath seemed to be getting clogged up. Immediately afterwards the drone could still fly (in not rather lound).
I trying to clean up the mechanism under the rotor as much as I could and it seems to turn relatively freely.

The problem is that whenever I try to fly it the entire thing leans to one rotor in particular (top-right to be precise). Crucially the slighly clogged up rotor is in the top-left - not bottom-right - which means this may not be to do with the rotors.

When I throw it and start the throttle the drone quickly flips downwards as if the bottom-left rotor is spinning too quickly. Please can an expert out there try and help me find a way to fix the gyroscopes on my drone...
 
HI mate look inside the quad I bet there is dirt in side the quads arm this will add weight to one arm so it will lean over that side

Thanks for the help but instead of the quadcopter just leaning to one side when in flight, it is spinning violently and rarely stays in the air for more than a few seconds. I've tried recalibrating it but nothing changed.
 
Do you have any stripped gears?

or

Try putting the props on wrong (CCW on CW motors and so on), and spin it up on the ground, does anything unusual happen?

Hi mate sounds like the FCB is damaged, when it crashed you may have blown the acc chip on the axis
 
FCB = Flight Controller Board, and SMD means Surface Mount Device. An SMD is a component on a circuit board that has no pins, and is just soldered on the surface. Hot air or lasers are the best ways to solder it.

Thanks for that. I'll have a look today.
 
I work for a major electronic OEM and aftermarket repair. SMD (or SMT) can be soldered very easy by a regular soldering iron. In fact this is how we do it for class 1 (medical) soldering. Hot air and laser not needed. Just keep your heat about 600* and don't hold on he lad too long.

A little SMD IC can be repaired with a regular iron, but it is harder, especially if it has a lot of tiny pins. The common probelm would be bridging two pins. So if you were to do it just be aware of that before you put power to it.
