Well, it appears I have about over a 150 hours on my original Inspire 2 and it has served me well. I have replaced the props a couple of times with the original props being removed and mostly using after market props. I have recently replaced the gimbal vibration dampners. I know not a lot of wear and tear happens in the motors except for the bearings but have decided to replace the complete motor assemblies, I should have them in a couple of days. I may also replace the complete retract assembly in the near future but have not found that item available yet. I will take photos as I do the replacements. If there is anyone else that has this amount of usage or more on an I2 I would really appreciate your input.
