As it is now it has to have full forwards and full left trim to come close to hovering, and I still have to push the directional stick somewhat forward/left. This leads me to believe that there is an issue with the right rear motor or blade/gear assembly. When spinning that motor by hand, it seems to have ever so slightly more drag than the other motors. It's very minimal, but I'm pretty sure it's there. All the gears on that motor look fine. The blade is not rubbing on the housing, which is what I was hoping the problem was.
Someone mentioned balancing the blades. How is that done?
I'm beginning to think I have a bad motor though.
Anyone have any advice on what to do next?
Thanks in advance.

I guess I'll remove them all and put them each on a sewing needle taped to the edge of a table or box. See if both ends stay parallel to the ground. If not, add tape or clear nail polish to balance. I'm hoping one of those two solutions work.
Could also be a loose boom, although I already checked taht on mine.
Thanks for the quick response. I checked the boom(s), all are tight. Haven't balanced the blades yet, but I did switch to the extra blades that were sent with the quad... sadly no difference. When I hold it carefully under the canopy and power it up half throttle w/o any trim modifications, there is alot more air under the front (white) blades than the rear ones. It feels like it wants to flip over while holding it. I'm thinking it's the right rear motor going bad. Damn.
It was fun while it lasted.
