I purchased a 9" Step Stool to use for takeoffs. However, when I tested it today, the Phantom Vision+ V3.0 initially leaned over, on takeoff, as if it was going to fall over to the ground when taking off. Fortunately, it corrected itself in time to take off successfully with no damage. I do a full throttle takeoff until I'm about 10-20 feet in the air. I'm not sure if the almost tipover was the result some wind, or perhaps the surface was uneven, or was their prop wash (I believe that is what it is called) below the surface level from which I launched as a result of being 9 inches off the ground but not flat surface beneath the level of the landing gear which are placed on top of the step tool for takeoff. I hope this makes sense. I'm hoping I can use this step stool to make it easier to take off from wet surfaces and snow for example. Sometimes, the grass interferes with the camera before takeoff. Any comments or feedback is welcome. I really don't want to have my bird tipover on takeoff. I'm already in the habit of hand-catching on landing. Here is a picture of the step stool... Thos are not holes on the top surface. They are actually filled in.
