Like you, I have started from scratch , not knowing much about rc sailboats. Thanks to a number of friendly websites on rc sailboat making, U can get tons of information & plans for making one or even information on getting a nice footy sailboat kit. As a good starting point if U really are new to this hobby, u may want to look at http://www.footy.rcsailing.net/.
I realised the footies that I have made are somewhat lighter than those made by others in other parts of the world because of the lighter materials ( eg sails, masts, hull ... etc ) used. Nevertheless, the lighter footy seems suited for the milder wind conditions here in Singapore's ponds and lakes.
I would like to end my first posting with a youtube video of one of my footy which I sailed recently at Little Guilin at the Bukit Batok Town Park. Hope you enjoy the video. Will begin to elaborate more on footy building on my next posting. Cheers. http://www.youtube.com/watch?v=58K964Me2mY
