Building my sparrow, I'm at the stage where I'm putting the servos in. Lookin at the plans it seems to be an ordinary servo. I went to my local model shop and they said that the one in the book wouldn't have enough torque. Is that true as they were trying to sell me a sail servo what is 4times the price. I have two systems one is a a four channel and the other is 2 channel both already have servos . which one do Go for

Standard size servo with high torque you need? Go for a Savox SC0252MG

Hi Andy
I've got both futuba and hitec servos that I used on a model plane. Will they suffice?

[Andyn]

Well what do you actually need them to do?

[nigel3a]

One to move the rudder, and the other to move the sails

[Andyn]

For the sails on an arm, I'd go with the 0252, rudder depends entirely on how big it is...

Hi, if you are looking for a cheap arm type sail servo have a look at the high torque standard servos that Howes of Oxford have, much cheaper than a standard sail servo smaller and lighter as well.

I've used the Howes ser1500 in a Victoria as the sail servo and a Futaba 3003 as the rudder servo.
I also have the S3003 in my marblehead so plenty of torque for the rudder.
Last year my Vic was run down by a trimaran tangled up with it and lay on it's side
full of water for around 20 mins until we rescued them.
After leaving to dry naturally for a few days everything worked perfectly.
Good enough for me and the price is right 
No connection with Howes. Just a satisfied customer.
