Re: AirMaster constant speed prop
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.
Re: AirMaster constant speed prop
All right John, now you've done it. That is so tempting. Think I will try this thing out the way it is and compare it to Paul's airplane at S&R.
Re: AirMaster constant speed prop
Custom Flight Creations has a pretty good article online about blade length selection for Airmaster CS props on Rotax 4-strokes. The tldr is that if STOL is really important to you, 75" is a good length, but that 68-70" is ideal for all-around performance. Seems consistent with John's comments.
