If you hold a commercial pilots licence then you are exempt the theory examinations. You will still need to complete the practical test though. Although we were exempt the theory we still paid to complete an abridged course, as there is a lot of RPAS specific stuff that we weren't aware of with over 50 yrs of Helicopter Flying and Instructing between us. I would recommend doing this as it was invaluable. I would suggest giving Aerial Motion Pictures a try for the training. They are a fairly new accredited provider and based near RAF Benson in Oxfordshire. Really friendly bunch and they follow the policies laid down by the CAA. Once qualified you can fly any airframe within your required weight range so they don't charge for you loads of money for extra tests on different frames. These are the people we used. Highly recommended!
Ok thanks very much, might give Aerial Motion a ring tomorrow.
