BadDawg, How many airplanes and radio systems are we talking about here? And how many are you going to fly right away? Bikerbc has a good point to only buy enough new batteries to get you started again. I would get two of my best flying favorite planes that I was comfortable flying before, and get them ready to go with new batteries, ground tested engines (taxi test them in your driveway), and progress from there. Having a good "copilot " standing by your side for the first flight is also a good idea. Enjoy !!
