Fellow flyers, dose anybody have a starting point for me on setting the pitch on a 72" four blade WarpDrive behind a rotax 582"

 

Thanking you.

 

Graeme.

That's a big prop for a 582!

I have just gone threw the process of having the RIGHT prop certified for my LW1 gr582. it all comes down to gear box and ratio as some box's on 582's can take a 72" prop,mine however is running a c box with 2.62:1 ratio and the correct prop is a 68" 2 or 3 blades. not sure about a 4 blade though?

4 blades at 72" with only 65 ponies to spin it at 6500rpm would require some torque I'd reckon.but just guessing!
