Hello Rufcut,

This is what I would do. I would 1st charge everything and check all voltage make sure all the battery's are fully charged and that they are holding a charge. I would move all the servo's and make sure they are all still good. I would go to the field and do a range check just to make sure its still good. I would put the fuel in the engine and start that son of a .... up . I would tune it up a bit if it needs tuning and make sure the transition of the engine is good. if all passes i would fly the heck out of the plane like there's no tomorow and call it a day. I hope i helped haha enjoy.
