Yea I have the manual
Actually I downloaded it from the site.

Something else interesting I found on there
the Hp at RPM for the 32 and the 50

They both peak at 17000 RPMs
The Sceadu 30 has a 9.66 to 1 ratio gearing and
the Sceadu 50 has an 8.7 to 1 ratio

From what I understand the head speed should be around 1700 to 1800?

If this is the case the 30 would be workin right in its range , with a head speed of 1759 at peak hp

The 50 size would be smokin the rotors at 1954 rpms at peak Hp

Now you wind them up to there max 20000 rpms , I see things startin sling off.

I just wish I could figure out when to leave the motor alone and start workin on the pitch curves
