Just purchased a new to me M3P a d was wondering what people find to be "must have" accessories? On my 2S the only ones I used with some regularity were battery bags, propeller clamp, and compact cases for the body and controller. The M3P already has a propeller clamp and I am not seeing anything else compelling. I will likely sell the RC in favor of an RCN1 so a screen protector is probably not in my future.
