Hi, I'm having some problems with my Phantom 4 drifting. The last time I flew it it was drifting around which is very strange because it typicaly was so stable and solid. Today I calibrated the compass and set the home base on my garage pad where I have flown several times before without any issues. I use the take off command on my phone and as soon as it lifted off it began drifting backwards towards the garage door quite quickly, it caught me by suprise and smashed into the garage door. I am wondering what would cause the drifting and what to do about it. (Put a pritty good dent in the steel garage door.) Thanks for any suggestions.
