One recommendation, and I do not mean to step on anyone's toes or discount the opinions of others who may differ, but I would NOT install prop guards on your Phantom. If you peruse this forum, you will see lots of threads referring to VRS crashes - vortex ring state - where the Phantom loses lift, begins to fall in its own prop wash, and ultimately crashes to the ground. Virtually all of these cases involve Phantoms fitted with prop guards. My suspicion is the prop guards subtly alter and disrupt the airflow beneath the props, resulting in the VRS crash. I'd love to see some wind tunnel tests to see what's going on with them. Given the number of VRS crash reports with prop guards, I feel replacing a prop here and there outweighs the cost of a camera/gimbal, or an entire aircraft. If she VRS crashes, you will likely break one (or more) props even with the guards installed (and the guards themselves!).
My Phantom's props have never touched anything but air and a few unfortunate insects. She has never tipped over on takeoff or landing either. For take offs, do NOT try to feather the throttle! Punch the throttle and let her jump up 6-8' and allow her to settle for a bit. Observe how she is behaving. In short order, she should stabilize, maintain altitude, and stay within a very small area. You should not see lots or vertical/horizontal movement. (if its really windy she will of course move around a bit more) When landing, bring her to within a couple of feet from the ground, then slowly reduce power and let her touch down. The moment she is down, hold the left stick all the way down until the motors stop. Do NOT perform a CSC shutdown unless you can't get your motors to stop. Doing a CSC sometimes makes the motors burp and this can cause a tip over. If you are unsure of your landing skills, hand catch the Phantom by the leg, and apply left down stick to kill the motor once she is in your hand. (use a controller neck strap so you only need one hand)
