    Cory,

    There's one photo where I could sort of see the tops of your finished wings.. Did you use a carbon fiber panel vs. aluminum ones for your 24 gallon tank covers? Remember the weight savings by chance, and did you have to do anything special for paperwork (I would assume not)?

    Cheers,
    Jeff

    Yes, those are Randy Apling's (Carbon Concepts) 24 gal tank covers. They are 7 lbs lighter for the pair than the Dakota covers and require no paperwork other than a logbook entry.

    Hows the prop working cory?

    We ordered 2 when we ordered them. One was for a 0-360 PA-12 and one for mine. The one that we put on the -12 was a little over a week prior to me finishing mine. He flew it for a few weeks and the nickel leading edge started cracking around the pins that hold it on through the wood. It looked like maybe they ground the welds too thin when they were finishing it. We have sent that one back to get repaired. So far mine it has held up good, but I only have about 5 hours on it. As far as performance, it is noticeably lighter, spools up fast and has pretty good performance for a 80" 44 pitch prop (the only cruise pitch they offer) . My real concern so far is with longevity... I will keep you posted!

    That's interesting. It's been a long time since I last worked on a wood prop. Those "pins" were wood screws and the "welds" were nothing more than solder to safety the screws. An old fashioned soldering iron was used to melt the solder in place. Do you have a picture of the cracks? It sounds as though it was the solder that cracked. Perhaps the "new" solder without lead didn't adhere as well?

    Thought I would update everyone on the prop. I have about 15 hours on it now and it seams to be holding up well. Lots of gravel bar landings and a few brushy spots. I try to avoid any brush with it, but have clipped a few that were unavoidable.

    I also spent the weekend With Randy Apling at Carbon Concepts learning how to make carbon fiber parts. He has this stuff down and makes some really nice stuff!
