I have used HS-225 on several applications and have had a number of them fail. I have stopped using them and am reluctant to try the HS-5245 because I understand that it's the digital version of the HS-225. By the way a friend recently told me that he had read that the HS-225's don't like 6 volt packs and will eventually burn out on them. Perhaps that was my problem since I use 6 volt packs on all my planes.
