AIRDOLPHIN PRO blade

[MIRELOS]

I have a Zephyr Airdolphin Pro wind generator on my cat, installed it 9 years ago and it has performed as expected; very happy with it. This winter one of the blades suffered damage and I need to replace it...problem is you can't just buy one blade, according to the dealer you need to purchase and replace all three and the rotator so that they will all be in balance. That is a hefty replacement; $1660 plus shipping. I have not found just one blade to experiment with the balance of the generator,.....asking for opinions before I pay the, what appears to be, large amount.
