I’m defiantly going to practice for awhile before I get my trainer in the air. I’ve looked around for some instructors in my area and there are quite a lot. I’ll just have to choose a place to go. The battery’s are more then 3 years old. The gentlemen I bought the planes for was very meticulous about his belongings. He had about 10 planes, all of them were hooked up to some sort of charger while in storage to keep the battery’s alive. I guess I could just change it out any way simply because I’m not really familiar with NiCd battery’s. I havnt used them since I was a kid, lol.
