I attended the course in York. In total there were 7 participants, although only 5 of us stayed for the full 5 days. The instructors (Kevin and Pete) were incredibly knowledgeable and imparted the information and skills in a relaxed and unpressured manner, which for a complete newbie to Drones was well received. I think the 5 day course was crucial for me to allow the information and training to properly sink in, whereas the 3 day course would have been far too condensed to fully get my head around the concepts being taught. All in all, an excellent 5 days, even when the weather wasn't playing ball.
