Looks pretty good. I don't know how useful they would be. They would be good to bring up the detail level on the older Academy H-60 kits, but look no better than the current Kitty Hawk H-60 kit parts.

This does look like a kit in its own right. And, if the Blackhawk does not require such an update, the Littlebird would greatly benefit from it. And a whole more besides. I don’t want to sink close to $200 on a kit, then need to buy a rotor set to bring it up to scratch. I wonder what Res / Kit may do for the pending Academy Apache...
