Hi Ray
Many thanks for reading my posting and taking the time to reply. It's true, anybody can post things on Youtube, and the fact that they are there is no guarantee of quality or exaction. It can make it hard for anyone like myself to find relevant tutorials or whatever on Youtube.
I like your Wild Duck model design and had thought of building it myself. I thought long and hard about it but unfortunately my rather confining home precludes I don't have enough room for many models. There are several models I've had to abandon any ideas of building for lack of space. I have just enough space for one more boat, the one Bermuda sloop I'm building. If I were to carry on, then the solution is either build a small shelter for the models in my small backyard or move to a bigger home. I have six R/C model boats, all at the moment on the floor of my lounge.
What type of tape, presuming it is a tape, you have used for the jib luff of Wild Duck?
