I think these should do just fine it's not like I am going to be flying all day every day. I am disabled so I fly some and then rest and then fly some more. Maybe a half of day of flying and will fly four or five flights with this plane and then there is other to fly. You know you have to fly them all or they get mad and then the little one's start fights in the hanger>>>>>>> Thanks for the info and the web site has a lot of good info thank you
