    Tom, One thing which you might consider, is to install an electronic fuel flow/consumption instrument. The Cessna gauge is notoriously inaccurate reading high, which it seems that you are referencing. That engine, at that power setting should be using less fuel per hour.

    Tom, I've made several comments on past threads about my XP Mods 14" tail wheel. You can find them using XP Mods in the home page search box. If you plan on using 850 or smaller tires you'll probably be happier with a smaller tailwheel that doesn't reduce the AOA and is easier on the tail spring. I switched to the ABW wide fork on my own plane.

    Can't tell- is that a 14" XP tailwheel (with 500x5 tire)?
    A previous owner put one on my 180 but apparently it had an uncorrectable shimmy problem. He went to an XP 10" t/w which is still on it and works great.
    If & when I ever go bigger, it'll be a BW fork kit and 400x4 ribbed tire.
    Cessna Skywagon-- accept no substitute!

    God I love this forum.

    Thank everyone for the posts.

    It has 800x6's on it now and with that tailwheel is does have a rather shallow AOA. I wonder if Its possible to replace the tailwheel with a small/standard one with that fork and hub. Havn't had the time to look into it.

    Pete,
    I am looking at a JPI 450 sitting on my desk ready to be installed along side the JPI 700 on the plane now.
    I do plan on running LOP when I get comfortable with it.

    No, It doesn't have a tailwheel lock....strange I guess.

    Just put the standard hub and tire on the fork, will work for you.

    When I get home I will look around, I think I have a stock fork off my old 180 that might work for you.
    I don't know where you've been me lad, but I see you won first Prize!

    You should be able to install a standard 3400 8" or 10" fork on that head. Or an ABW wide fork if you prefer improved flotation. The XP head casting is hell for stout. The near vertical fork in combination with the big tire is what makes them balky to steer, prone to wobble, and hard on tail springs. Some of your steering issue may be related to the 185's rudder centering system. No matter, the smaller the tail wheel the better it'll steer on suitably firm surfaces.

    Thats good news.
    So a standard fork and hub and tire should work on that head.
    I will have to explore that option.

    Here's my ABW wide fork on an XP head. The trail angle of the fork works way better than the more vertical XP fork for ground handling. Watch the attachment of the head casting to tail spring on any Skywagon tail but especially with the 14" XP. The two attach bolts will start to wallow out the spring unless you use structural epoxy to bond it and most float guys don't like to bond it because it makes float changes more difficult. Rock the tail and make sure there's no rotation movement between head and spring. I still check mine frequently.

    Ha-ha! I just saw this and burst out laughing. I had my Skandic WT wide open the other day and hit 50mph - that little Ace 600 was screaming. 20-22mpg, though, which is certainly better than the hi-perf sleds.

    Those are great numbers. Doing the simple math your high burn is getting you 13.75 miles per gallon
    My Carbon Cub is about 100 mph at 6 gph or so is 16 mpg


    Round yours up to 14 thats pretty close. If you look at used Carbon Cub prices, and 185 prices, and if your hours on earth are valuable, well that sure gives you something to consider
    A 300 mile trip for you would be1.8 hrs, and 21.6 gallons gas
    A 300 mile trip for me is 3 hours and 18 gallons gas

    The new Cirrus i flew last week at sort of a low cruise 172 kt at 14 gal is about 12 mpg. My young wife in the back says the seats much nicer in the Cirrus than mine.

    Lord help me get my head back into this boring meeting

    That's like comparing a 3/4 ton pickup to a Prius. The Prius is cool until you need to go to the lumberyard.

    In Mackay Id. the other day, talking with another pilot who had a 180, he got a phone call. I overheard him saying he'd be back in half an hour (to his home base), and I laughed. Then I told him that town was an even hour at my S-7's cruising speed, and we ended up both agreeing I need a 180, and he needs an S-7. I burn 2.7 to 3.2 GPH, he burns 12, but one thing for sure, at the end of the day I get to log more time.

    Haha! My Prius holds more than I would have expected. I can
    get a 10 ft piece in it. Barely.

    But if it's 10'-1", I take the pickup and maybe the flatbed trailer.
