    Default Props

    I was wondering how I could find the performance differences with my S2 between the Catto and the Mccaulley 71x41 I currently have?

    Randy, is there similar prop - pitch information for the O-340 in a Carbon Cub?

    Pete,
    I had Lycon build the entire engine with those options. They supplied all of the parts. I almost went with a single electronic ignition but was told that low altitude engines don't benefit much from that. I don't know how true that is but I can say that my engine with the 2 mags starts so easy it's scary, I never touch the prop with the mags on. It runs incredibly well and smooth. I do have a Dyna Vibe prop balancer which makes all the difference.

    I agree, dynamic propeller balancing is a great way to reduce vibration levels for your aircraft.
    I use the DSS Micro kit which works very well for me.

    What kind of plane do you have that motor on? It sounds like a well thought out build.

    Rich,

    Consider the Sensenich ground adjustable composite prop, it has immediate thrust and the climb pitch cartridges 46 and 48 outperform any of the other props when in STOL or back country conditions in my opinion at least!. I have about 500 hours on my prop and nearly 1000 hrs on my cub. How muchlong range cruising do we really do anyway? If need be, just change the pitch cartridge to 50 or 52 for a long cross country. Takes about 15-20 mins.

    Have fun my friend, ...Geo

    I second Geo's recommendation. Light weight, pitch flexibility, and great performance... highly recommended. R

    I have always felt the supercub is one thing mankind got right the first time but that there were better materials and methods to build them. CubCrafters products are proof I was right.
