Okay so, just got my spare props in the mail so i took SOLO out for a flight, and everything was working fine, responding well. but my battery life drained SUPER fast (thought it was just because it was cold out) anyways i hit home button and solo comes back to where i told it too, and i told it to land... it comes down at its normal pace but about 10 feet of the ground it starts dropping rapidly and it hits the ground fairly hard and bounces a little bit but i recovered and turned off the control to get the props to shutoff because they didnt shutoff like normal once landing. so my question is, did SOLO just land like that because it was low on battery or is their something internally wrong?
