Jankers:
Hi,

I need to fit a mini steering servo in my model Blu flu boat.

Itis  a 32 inch long model of "Hector".

Anyone used these http://cgi.ebay.co.uk/E-SKY-8-gram-mini-servo-UK-ONlY-GBP4-5_W0QQitemZ6036124247QQcategoryZ34056QQrdZ1QQcmdZViewItem

before?  Any advice?

J.

Doc:
Jankers,
Not knowing anything about your boat, the only advice I would give you is to be sure the mini-servo is powerful enough to do what it's supposed to do.
I've used mini-servos, but only because of very poor planning on my part, just no room for a 'regular' servo in the space available.  Made sure there was ~no~ binding on the rudder, not exactly thrilled with the outcome but it works.  Good luck...

Before buying a servo from an ebay supplier in Hong Kong, check out the prices with Robotbirds, a UK supplier who I have found to be very helpful and good value.

Or you could try Hunter Systems or Howes of Oxford in Kiddlington. both palces offer very good advice and can be a lot cheeper than someone in Hong Kong, ( if anything goes wrong its a long way to go to complain). Both firms I have found deliver next day.

Hope this helps
