Dave, If you plan to run a 4 stroke then make sure your props are balanced and the engine is tuned properly. Unlike 2s engines the 4s variety are not forgiving for bad tuning or props. They will vibrate excessively. Like all ARFs it is a good idea to go over the entire airframe to look for areas that might need a little extra attention. This is especially true when using very strong engines. I would recommend checking the engine area, wing tube sockets, wing attachment locations, and where you glue the tail on. Be sure all areas are properly glued and secured. Some extra CA around the wing tube sockets to ribs and more importantly the wing tube sockets to shear webbing is a good tip. Injecting the engine mount area with Gorilla glue is up to you but would be a nice tip as well. Vibration kills an airframe.....especially a light high performance airframe.
