I have a fc40 and looking at sticking gimbal and gopro on it, i also was looking at putting a new set on props on for better flight time either 9443 or 9450 props have been mentioned in this forum, spoke to a guy at marionville models and he told me not 2 bother as i wont get any benefit at all as the fc40 was so light anyway! Just wandering what the general thought was on this subject?
