At some of the sites (mostly Ma On Shan and ShekO) there can sometimes be remote controlled aircraft being flown at the same time as paragliders are operating.
Whilst it is generally safe to fly at the same time as the RC aircraft, try to avoid flying too close to them.
At Ma On Shan their launch site is in the "bowl" to the north just before Pyramid hill.
On Strong wind days there will be more RC activity, and generally there is enough lift for there to not be a problem. When the lift starts to drop and you require to fly near the cliff is where we sometimes conflict.
Please read the presentation about Avoidance MOS_Radio_Control_Club_Glider_avoidance.pdf.
Pragmatically, if you need to fly near the cliff, try to get enough height and fly overhead and slightly behind the RC pilots, this will.
The message here is try to cooperate, but remember at all times, if the RC modellers are flying too close to you land and approach them politely and express your concerns.
There have been examples of paragliders in mid-air collisions with RC models, so please be careful.
If you feel that safety has been compromised please contact the safety officer (firstname.lastname@example.org)
