You don't want something like these ? - 470mm x 43mm

or if you can fit another 30mm, these;

Unfortunately the next size up is 515mm, with 53mm chord and 12mm root, so they probably wouldn't fit in 500 size blade grips.

I run Spin asymmetrical 465mm x 51mm on my recently deceased UH-1N at 1700rpm, and it flies well with plenty of lift - they do have rounded tips though. From memory there was plenty of space between main and tail blades with 465mm, so longer blades could probably be OK.

Vario Long Ranger 700e
Seahawk 600
UH-1N 500
Baumann EC-145 800+ (coming soon )
