High altitude props?

[Damien]

I've heard these exist for DIYers, they have a different profile (higher pitch) designed for low density air and don't work well at low elevations, but I'm wondering if anyone knows of some that could fit Solo.

Not a steeper pitch, but longer...see the linked thread.
