New high performance Hartzell Prop now Available! 

I'm pleased to announce the availability of an improved Scimitar style prop from Hartzell. Flight test was performed in Nov 2011 with Mike Smith's SX300 , IO-580, with 10 to 1 pistons. It basically is a Lancair Legacy blade with an improved hub that fits our aircraft.  The spinner backplate requires some modification [see photos below]. The weight is approx 80 lbs. The diameter is full 75 inches [legacy blades have 1 1/2 inch cut from each tip for their ground clearance]. Performance has not been definitively determined , but a 3-4 % increase in efficiency/thrust gain might reasonably be expected. We plan to have before and after figures after some installations are complete. These props are available through the SX300 Group for a total price of $ 9,625.00.  This includes the 3 blade prop with hub. Spinners are available at extra cost of $800.  The total price is $9,459.00 which is the OEM price from Hartzell + $166 charge to try and recoup $1500 in fuel and hotel expenses associated with the Flight testing . Lead time is 6-8 weeks. Orders must be placed through the SX300 Group. Full payment is required and then the order will be placed. Make check payable to : SX300 Group. Mail order and check to:

Also freight is the responsibility of the buyer. My cost was about $250. I assume future costs will be about the same. I have a request in to clarify/ confirm the actual shipping cost.
