Thanks everyone for the replies; Really appreciate everyone's help!
UPDATE: Took her out after work last night and things were better. Only went about 200 ft + because things still didn't feel quite right. Signal issue seems to have been resolved, still REALLY bad video relay to the mobile device but whatever, I can handle that.
The thing that is scaring me is the uncontrollable drifting and incrementally climbing in altitude with my hands completely off the sticks. Maybe the drifting is product of wind gusts as it was a bit windy yesterday, but I was wondering if strong wind gusts can produce enough lift on the propellers to make this thing climb without me hitting the gas? Anyone ever seen/heard of this before?
I've got a commercial shoot scheduled for tomorrow, hoping to get in one more flight today, and if things are still behaving strangely I will probably cancel the job due to not being comfortable with the operating condition of my craft;
All of this is strongly making me consider Autel, Yuneec, or even a 3DR for my next purchase; DJI and these firmwear issues, it's just ridiculous
