I visited the best flying field in Hong Kong, HKMEC (大棠遙控飛機場).
It is located at Yuen Long town (元朗), 50km from Kowloon.
I was told this is the only legal RC flying field in HK.
It has a 200m X 20m concrete runway, and a 800 sq. meters concrete helipad exclusively for helis.
It has also sizable covered pit areas with workbenches and chairs with electricity supply.
Container storage facilities. Very importantly, toilets.
If you are lucky, you will meet this beautiful dog.
Or, the "Security Team".
