I have read recently that the std. servo on the sail arm of the "weenip" is sometimes not up to the job and needs a little help by bringing the yacht up into the wind to take a little pressure off the sail.
I have not sailed my wee nip yet, nearly finished painting, and was wondering if I need to source a stronger servo before I do.
If so what do I need to look for and buy??????
Thanks for all help so far. Question Confused

The Fed rules state, standard servo's, as per the original Nip spec. to keep all Nips on an equal keel & it keep costs down.

They are NOT strong enough to pull the sail in against the wind but everyone is equally handicaped, then it's down to sailing "skill" Cool

If you sail alone, you can do what you want. Rolling Eyes

Nips are about FUN, not, who has the deapest pockets.

Thanks for reply Eddie, fully understand the need for uniformity within the regs. If I use the std. servo the by-product is thhat it should teach me to be a better skipper.

On a wider issue if I had wanted to change the servo for a stronger one, I still don't know what I would be looking for? How are they specified in caalogues and rated etc.

Seasons Greetings to you all, I think my next project might just be an "ice breaker"!!!!!!!! Smile

Hi there
IF you were to change to a sail servo
then something like this is what you would be looking for

http://www.cornwallmodelboats.co.uk/acatalog/hitec_hs765.html



It is a basicaly a normal servo but is reinforced for sail
and the larger servo horn gives more control of the sail movement

Would someone like to define a "standard servo"? Howes web site currently lists sixteen "standard" servos including a 6.5 Kg ( Kg cm) servo for 9.99. Buy a decent "standard" servo rather than limit yourself by getting a crap one! Another point, the voltage of the battery pack has a significant effect on the output torque of a servo. A new 4 cell pack of Duracell batterys will have a voltage well in excess of 6V whereas a 4 cell nicad pack will probably be about 5V. Finally the standard servos that came with my current radio outfit are digital.
