Hi Rogal, enjoy your beautiful model that sails very well.
You worked well and can forget about fires or other disasters (nothing broke, fell off, melted, or fused).
You've put the protections in the right place but if you want to feel even more comfortable, read Tomarack's article in the topic "A wiring mess", on this forum, it's the fourth message.
Although very long it is very interesting and accompanied by drawings. Among other things he also talks about fuses.
Sorry I only found out about it now even though it's from nine months ago.
