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?

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

check out www.howesmodels.co.uk
 you can buy a Hitec HS-50 servo direct from them (near Banbury) for ?13.50 - I know it's dearer than the Chinese gear but you know what you are getting with Hitec

spec says

The Hitec HS-50 servo is a modern miracle of miniaturization. Featuring precision components that have been engineered to provide long lasting trouble free service. The HS-50 is the perfect choice for any micro application from indoor R/C and hand launch gliders, to ultra small electric Park and Yard flyers, Speed 400 and 1/2A powered aircraft.

Motor Type : 3 Pole Ferrite
Bearing Type : None
Torque 4.8v : 8.3 oz/in 0.6 kg

Thanks for your replies guys.

I used the ebay as an example as the servos listed in the uk
seem to be similar to the one aston specified, ie 0.6kg or thereabouts.

The Hong Kong example lists 1.3kg, about half that of a standard servo.

I have found some examples on the Howes sie that may fit, but, having never used anything other than Futaba
or Acombs standards I just wondered if anyone had experience of the mini variety,

Time for a little more research.

I ahve used mini and micro servos, one in the Revell S-Boat moving three scale rudders with no problems, on in a 1/350 Yamato and the other in a Astec Falcon FE all with no problems.

I have used the Hitec servos I mentioned earlier in a couple of models, the latest being in  my modification of the RNLI Severn class which they are selling as ready to run. Mine now has proper radio and motors and is geat fun.  I also have one in a billings Waveney class ( the small one, about 14") and in my Heller KGV.  All run perfectly.

I use mini servos in my small plastic models that are remote controlled, no problems either, but have you considered mounting a full size servo on its side or inverted?

Bob

[Jankers]

Shipmate,

Yes, did consider it but no room.

I think I've cracked it, can get a servo ar a local shop
which aught to fit, allbeit a squeeze so shall give it a try.

I have installed three E-Sky mini servos in my submarine and the do the job adequately. I was not pressed for room but I used them to save weight, I do not know how long they will last but they are working great at this time..

I bought one of these servos to try in one of my small fast electric boats. The micro-servo certainly has plenty of torque but I did notice a certain amount of slack in the gears when using the longest control horn (approx 1/2mm movement in either direction). I then decided that I would be better off using a mini servo. The ones that I use are made by Supertec and the model is called a Park flyer servo. They are available from Micron ( http://www.micronradiocontrol.co.uk ) and cost ?8.50 each. I think that the E Sky servos would be fine in a small scale boat or in an application where precise control is not essential.
