I still have that building instruction booklet. Also have the wooden model boat, pretty old and needs a refurb, has an old 500 series electric motor, will be replaced with a brushless one. I also have just the fibre glass hull with the deck on it but no superstructure on it. I hope to build a top for it, but it will probably be totally different to the original one. I am planing to replace the IC engines in my other boats with brushles in most of them. One or two of the smaller ones that will be too over powered with brushless motors will have brushed motors that will give them the speed I want. I'm a bit of a speed freak. The only one I will keep with a resonably slow brushed motor will be my recovery boat in case it's needed.
