Good luck with your maiden, and enjoy

I see that your switch is not mounted to the fuse,

I hope you are not planning to put and remove the wing to turn it on/off.

One suggestion is to put that switch on the left side of the fuse with ON at the back. This way if you hit something in air your receiver have a chance of being ON. This is ofcourse if you hit something in air and survive.

Leaving the charge side out of the plane on left helps to measure the battery, you don't have to remove and put all the rubber bands every time.
