Have you flown it yet? If not then find a place away from anyone and fly about 50-100 feet AGL and get a feel for the way the AC responds to stick movements. You may wish to change the stick sensitivity, particularly the yaw, but spend a few batteries just learning the feel of flying before doing anything more advanced. You also want to develop the muscle memory of not only the flight behavior but also flight times on the battery etc. Learn to scan the sensors so you know how much battery you have left and how strong your comm is.
Also, get the tools you need to avoid flying where you shouldn't. The FAA based "B4UFLY" app, available on Android and iOS, will help but keep in mind the app is pretty poorly made so it may take some time to figure out its idiosyncrasies.
It would be a good idea to have another person along to keep an eye on other people and assist with monitoring for planes and helicopters -- if you have older children (12+) you can bet they will be more than willing to come along to help but do know they will likely want some stick time to.
