Hello, This is my first post. I have been flying the phantom for 6 months. I have spent a fair bit of money to fix the flight problems I've been having recently but without success so far. I'm hoping you might have some sugesstions here. I have mounted tiger motors on and carbon props and have had great flights until a crash which im still recovering from. I replaced the props and shafts, and it flys well in all directions except trouble on ascent and descent which is very unstable. the phantom for a while has also had trouble staying stationary in GPS mode. I have calibrated the gps and updated the firmware. Even though I replaced the shafts, some appear to have slight wobble when i observe them on the ground, and i wonder if this is the problem. are my motors now garbage from that accident? i would suspect that if i can observe wobble that I may not even be able to rebalance the motors if this is the result of a deformation in the motors themselves. I also wonder if the compass could be broken, and have ordered a replacement of that too. Thankyou for any sugestions, any help would be appreciated!
