We are a dealer for AirMaster..
75" slightly better STOL if that is primary...
70" does an awesome job Eddie so not to worry.
Approx $8300 for the 70" delivered.

Have used both lengths... the weight is about 23-25.. which usually means about 10 lbs heavier then a group adjust.

Easy to operate and works well..

You simply cannot beat a CS prop for overall performance.
It will depend on engine choice and flight mission.

$8300 is a bit much but actually cheap when pricing CS props.
The 3 blade MT is $11k and the hydraulic governor is 2-3k.
