Hi,
I have a walkera 35 6ch with metal head and belt tail.
From where can i get spares like boom and main shaft in india.
Also need some repair advise from a experienced person
I am not sure who sells Walkera in India. Since these are parts (which should not cause you problems with customs etc), you may try to get them from HongKong/Taiwan based shops like :
http://www.ehirobo.com/shop/index.php
http://www.rc-fever.com/
both of which I have shopped at least once before.
Since the 35 is discontinued, you may need to look at substitutes from other Walkera models.
Let us know what help you need in terms of repair. We have a bunch of heli folks here, so that part should hopefully be easier than sourcing the parts.
Since you are in delhi, you could pick up 35C parts form model art.
