    They make it challenging with a cross wind, shimmying Baby Bushwheel tailwheel 250 lb passenger at gross weight. No shimmy today with the 3200 and the landings were a piece of cake but you better not drop it in cause it'll jar your teeth. Add in the comments from the back seat FAA test pilot when the landing isn't so smooth.

    I have had my 82” GA prop for several months, but then I figured once the certification happened (long over due obviously) they would be hard to get. Hence I ordered mine a LONG time ago.

    I like having things in hand even well before I need them.

    Steve why is your gear splayed soooo far OUT??? Can't imagine how far that must tilt those tires when your at GW??? Is that being caused by the shocks not having correct tensions; to hold the weight of the plane?? Not being critical here, just an honest question?

    Earle, it will be interesting to get Steve's take on this but I think you will find it works best for the type of off airport landings he is making down his way. The developers of the shock systems we are seeing the last few years refer to the travel limits of there systems as compression and sag. Most recommend exactly what you are referring to as preferable because it increases the overall distance the unit is allowed to travel which simply means more usable shock absorbtion in particularly rough ground. And I suspect the slight splay out might also increase stability at touch ground on very rough areas? Interested to hear the take others have on this. The monster shock system I use talks about setting them up to allow that extra movement. I prefer a more level stance for mine, but i am not generally using like Steve does down along the river.

    Yes, but what's with the tiny tires on "Double-Oh-Six" in the back corner ? The Sensenich prop should work great on a Scout.

    Thanks. cubscout

    Concluded the landing test yesterday with 6 landing starting at dawn. Will schedule the noise testing in a few weeks and we are hoping to use my airplane since I have approval for the prop and would save switching the airworthiness certificate from standard to experimental which involves a DAR coming from Waco twice to do. I will have to take off and climb over the microphone at a certain altitude. This is the last step and hopefully the data will get processed and submitted and an STC granted soon.
    This is the test airplane with the ground adjustable prop.

    The crew. I learned a lot about props from Jon Bristol and Steve Boser at Sensenich and a lot about test flying procedures from Tom Bryant. Bob Brock kept all the i's dotted and t's crossed.

    Debating on which prop to put on my project. So once this prop becomes certified how long before they’re available?

    A friend of mine has a PA 12 with an O320 on the front and is looking for a prop. When this prop is certified for O 320 will it only be for the PA18 or will the certification include other piper taildraggers with similar type certification PA11-PA12-PA18?

    Just curious, but why wouldn't the noise test be conducted in the same configuration (same aircraft) as the other performance testing?

    The STC will be for the PA18 with an O-320 engine installed both 150 and 160 hp. The prop is type certified on the O-320 and O-360 engines and that data along with the STC data for the PA18 can be used to get a field approval or DER approval of the prop on other aircraft. It has gotten approval via that route on a 180 hp C172 converted to tail wheel and on a Pacer. I was considering pursuing an STC for the Pacer but having seen what this project took I don't think I have the time, patience or money to do it.

    The performance data has to be interpolated to come up with the altitude at which the altitude the airplane has to climb over the microphone on take-off. The aircraft would again have to be put into the Experimental category and then back to standard which takes a DAR two trips, expense etc. If I use my airplane which has approval to run the prop it can be one trip to prove compliance.

    Ok, thanks. I was assuming the test aircraft would be dedicated to the program and stay experimental until the program was completed.

    Problem if you leave the airplane in Experimental R&D/Show Compliance is based on 91.319, it can ONLY be used for the purpose for which it is Certificated. If it stays Experimental, it can only be used for the testing and nothing else.

    That is why it was returned to standard and to it's owner. We never know how long these things are going to take.
