Right on Piper!!! Always check the balance, you don't have any idea who put that mess togeather and if they were having a bad day or maybe wanted to get even with the world, besides that is something you should practice with every plane you will ever fly. Who knows how many mice made a home in your tail and now you have a plane that is going to give you a fit. ( Buddy-- this is experience speaking, mice in the tail ), also had a battery shift on a students plane, that was a lot of fun. ENJOY !!!!! RED
