Life conspired to drive me away from RC about 5 years ago. I just started cycling battery packs and cleaning engines. All my stuff was gold stickered, so I am assuming they are still legit (or have things changed?) Since I haven't given my planes a thought for five years I'm feeling a bit more stupid than usual. Anyone have a heads up for me? Battery Gurus, what should I be looking for in tx and rx packs? How should they behave on cycling? Or are they all just toast and need to be replaced? All my engines were stored nose up with copious amounts of after run oil in them, so I figure if I soak them in light oil they should loosen up with out too much damage (or is there a better way to recondition them?) Any thoughts are welcome.
