When discussing insurance, in order to make an apples to apples comparison, there are a number of data points which are needed. Type of airplane, time in type, hull value, type of coverage (full in flight, ground in motion, ground not in motion) who the underwriter is, etc.
You should see a reduction in rates after the first year, assuming you fly enough hours the first year. I believe around 100 hours in type is one of the milestones where rates start to go down, but don't quote me. JT, are you monitoring?
In my case, when I renewed my insurance in April, I paid $921. This is on a 2004 RV-6, hull value $70K, and I had about 150 hours in type at the time. This is ground not in motion coverage. For the first year, I carried full in flight, at a cost of about $1600 IIRC, with a hull value $50K, and 5 hours in type. I increased the hull when I renewed, because of some eqipment I added, and decided that I had it under valued, so it is hard to get a good apples to apples. I do recall getting a quote for the exact same coverage for this year, with my additional time in type, and IIRC it was around $200 cheaper.
