nice decals dude/ss...interesting props - not seen that before. regarding the gimbal cover - The problem is not so much remembering to remove the gimbal cover as it is to remember to remove the gimbal lock (other wise leads to gimbal motor over load and possible gimbal motor damage)---some thing i did a few times until a mate got a two in one (gimbal cover with integrated gimbal lock) from usa for me.. never had that problem since.
Happy flying
