In my experience the Feigal XL motors tend to run a little bit hotter than a Lehner or a Neu. My 540C 9XL on 5s tends to run around 160F. My Neu 1515-2.5D has an almost identical KV rateing and runs a good 20-25F cooler in the exact same setup.

With proper gearing, you should not have any issues. Running as high as 180F is still safe and nothing to get worried about.
