Friends pls advice us a good motorised remote head for JVC HD100 camera for our 10 m jib crane.

I've shot extensively in India- are you looking to rent there or buy? If buying then most heads will work since it is a lite camera, but you will need base plate and iris rods to mount a motor for the focus control and you'll need an extra long Fujinon zoom cable and powered controller. I would suggest for local consulting on what is available in India to contact my friend there who is very knowledgeable and has much experience in this area. He has shot with me both in India and the USA. His name is Husain and his contact info is:

Tell him that Keith Gruchala sent you.
