The Heller Soleil Royal is an extremely controversial topic in ship modeling circles. We've had several, sometimes rather emotional discussions of it here in the Forum; the longest is this one: /forums/679595/ShowPost.aspx
As will quickly become obvious in that thread, I'm among those who have an extremely low opinion of the kit. But take a look at what others have said about it. It obviously has its admirers - and it's not for me to say what kits a modeler should and shouldn't build. I just think the modeler has a right to go into a project with his/her eyes wide open.
Just about everybody who's tackled the kit agrees on one point, though: the rigging instructions that come with it are a disgrace. As I've noted in that other thread, the people who designed it apparently were enormously talented artisans whose understanding of real seventeenth-century ships was at best extremely sketchy - and the kit shows it. The most glaring example: it provides no means of fastening the yards to the masts.
Fortunately help is available elsewhere. Anybody undertaking this kit - or any other seventeenth-century warship modeling project - would be extremely well advised to acquire a copy of Dr. R.C. Anderson's book, The Rigging of Ships in the Days of the Spritsail Topmast. The rather arcane-sounding title notwithstanding, it's a step-by-step guide to rigging a ship model - with notes about the variations in practice from decade to decade and from country to country. The book was originally published in the 1920s, and the modeling hints in it are sometimes a little dated. (And Dr. Anderson, obviously, never heard of a plastic kit.) But the information about how rigging works is just as valid now as it ever was.
The book is available in a very reasonably-priced paperback edition; sources include Model Expo, Amazon, and Barnes and Noble. I picked up a used copy a year or so ago for about eight dollars. That's money very well spent.
Hope that helps a little. Good luck.
