Glad and pleased to hear that you are going to take some good advise. On your batteries just put them and some foam up where the tank use to be. On new years eve I took mine out and with lites adorned and spot lites handy flew out the old year and landed in the new year. Was quite thrilling to do this and am looking forward to do this nest year too. Flew a total of about 15 mins and landed with no problem. Maybe some time this year we mite meet at an event and compair planes and notes.
