Had a similar problem with my hex and the long-legged tripod-type landing gear that came with it. - tip-over after tip-over. Lost a few props that way (plastic practice props, to be sure, but lots of them broken none-the-less).
I bought a kit which allows me to attach several different devices to rails that are mounted to the under-side of the 'copter. I then made my own landing gear out of (hang on to your hats, folks) balsa wood popsicle sticks. Just glued a few of them together (flat-side-to-flat-side) cut them to size and shape, and attached them to the rails with small screws.
They have a wide-enough stance to negate the tendency to tip over on landing, yet they are strong and still light-weight.
Sometimes the older stuff works better than the newer stuff…
