In asking about a US distributor in another thread I was able to get ahold of Carlos at Helicopters International in Florida. What a nice gentleman. He happens to have a new set of 23' GT blades and hub bar that we are in discussion about currently. But I wanted to consult the Forum before making any big decisions of this importance.
They are the "Modified Airfoil" design, which has a slightly smaller chord than their standard 8H12 blades (GT recommended the larger Standard blades for my Bee). When I went to GT's site to refresh my memory of the differences between the two blades it appears the Modified airfoil blades have been removed from the site.
When I first learned of Gyro-Tech I thought the smaller Modified shape would have been best suited, since I don't see many light single-place ships slinging 8-1/4" chord blades. But GT recommended otherwise when assessing my needs.
Nonetheless, I may get a great deal on the other style since these are already in stock in Florida, and apparently not being pushed anymore by GT if their absence on their site is any indication. So now I have to consider what performance hit there might be as opposed to the standard blades... if there is a trailing edge reflex that would make manual pre-rotation more difficult (a-la Dragon Wings), and if there would be any negatives to using this blade for reasons I don't yet understand as a newbie.
If the fine folks here have an opinion I would be grateful for any feedback before proceeding further. Thanks in advance.
