Roy, I'm glad you've decided to stick at it, and with all the help available here, I'm sure you'll make a good job of it. I'm not buying into the kit v scratch built debate, other than to say I have built both, and enjoy both, but lean towards scratch built for the satisfaction of making as much as I am capable of.
I have built 3 kits, and I will mention names because I am happy with all 3. My first model boat (after years of RC flying) was an Artesania "Amsterdam" tug, which I found to be an excellent beginner's kit, with very good instructions, beautifully illustrated. It has quite a spacious hull, which made the installation of the motor, drive line and radio quite easy.
My second kit was a Model Slipway "Sentinel", employing different techniques, (printed styrene sheet as opposed to die cut ply in the Artesania kit). Again, the instructions were excellent, and the feedback from Jackie and Lawrie at Model Slipway was brilliant. The hull in this case was rather less spacious, and some careful thought was necessary to fit the two motors, two ESCs, and radio gear in, but help was offered in the instructions.
My current, almost finished, project is a Billing "Nordkap", which again has different construction techniques to the first two, being plank on frame. The instructions are not perfect, but Billing do state that it is intended for modellers with some experience, and I'm pleased it was not my first kit. There are virtually no instructions for making it a working model, as it is designed primarily for display. However, the model is shaping up well, thanks to experience gained with other kits (and several scratch built boats) and should be on the water within the next couple of weeks.
Good luck with your model Roy.
Peter.
