I didn't want to spend a lot of money on a quad in case it didn't work out for me (fun-wise.) The U49W seemed to be a good starting quad from what I read. I read the manual several times and watched numerous videos before trying to fly it. I was trying it in the living room due to windy conditions outside and all went well. Had the expected slew of minor crashes but all in all, I was learning.
Today I was flying it around the living room, had a couple of low speed crashes and then the quad would not lift off. The motors started but when trying to lift off, it just tilts the the right side. Tried the trim button but no change. So I changed the props and did the calibration according to the manual and now it tilts to the right rear instead of lifting off. I checked the props and they are on correctly.
