My 1/10 Jolie Brise hull has been sitting on the bench for over a year as I find a winch to power its Main and Top sails. The sheet load is over 6kg.

I started to test sail drum servos to see exactly what they would pull. The first one was the Hitec 785. To my surprise it did not pull the load the box says.

The results of research and testing can be found in Before Buying

It includes

Online calculators to find sail sheet load and servo speed.

Product specification for all drum servos

How receiver outputs effect sail sheet travel
