Newbie to RC sailing. Sparrow build progressing nicely, but need some help now. I have a sail winch I got from a friend and was wondering if it is better to use a winch or servo with long arm to control the sails?

The winch is trickier to install and possibly a bit heavier.  Personally I would stick to the instructions in the book. But it comes to personal choice really.

well i went with the sail winch on mine boat for the reason as they are made for the job. I had a sevo on another boat and the sail load did it in twice...could not fit a larger one in....
You do have to do more set up but once it's working there not much that can catch you out.

Thanks for the advice. Will do some trials with the winch as I already have it. If I battle to much will buy a servo.

Hi Racing Sparrow

I cast the lead keel bulb and dimension wise it came out great, but only weighs 950 grams is that ok? i see on the plans it says 1.2 - 1.3kg. I could add some more lead if i cast the keel in using lead.

Sorry, only just saw this now, you might get away with 1kg. Depends if you sail in an area with high winds. If not it should be ok, maybe make the smaller sail set also.
