hi I have had my hex over 3 months and many flights which have gone well no crashes or hard landings that is till today I had a arm fail a crack just after the motor mount on the front left it was just a bit of luck as the hex was only at 5 ft and flying towards when it let go the motor took a dive and I shut down as soon as it made its untimely landing or crash I had a spare arm and fitted it tonight and test flown it I hope this was just bad luck and not going to happen again any ideas should I change all the arms or just fly it,I changed the prop on the broken arm as it took a tip off has anyone had a the arm fail it is like a dji pattern arm.which I have a 450 with gps but the bolt size is not the same.
