  1. Yamma-Fox added a post in a topic Yamaha 4 stroke engines for sale   

    Sound like great deals to me!   There would be some extra parts to buy on ebay, but only a few hundred dollars worth.
    Only concern would be that the motor couldn't really be tested, so a little gamble there.
    Note: The 3cyl would be a model that would not work with teal's skytrax kit.  Very few of these have been converted, and there is not much support available in converting them (at this date).  But I assume this will change soon (see william langford's posts over in the Yamaha Aero Engines Facebook Group)

    Sounds like a polish job gives good results:

    I've seen these in action on a snowmo.   Pretty darn impressive!
    At this price it would be worth giving them a shot.  If you don't use them on your plane I'd bet you'll find another use for them.
    How you mount them is the challenge.

    .... shoulda posted this in jokes...
    Anyhow,  the frequency of fish I catch is often close to what that "pea method" is good for. 
    My kids love going out with me, but tell me to test the bite and if it is just gonna be 'fishing' then "keep trying on your own and let us know when it gets to be 'catching', then we'll come along!"

    Oh and for you boys down south, that's an ice auger hanging on the wall.... good for when I go out fishing for ice....  afterall, they named it "ice fishing" because of what you usually have to show for yourself!   LOL

    How many MPH does a belly radiator cost?
    Been wondering this myself, and have seen others ask the same question.
    Has anyone ran a belly radiator like mine pictured, then either added an aero fairing or moved in the cowl and noted a speed difference?
    Mine is sure a big beastly spoiler (oversized monster to keep the old subaru cool).  I'm betting it costs 5 mph.

    Looking good!
    You have a grass strip up there by Cotton?
    And don't forget:  tricylcle planes make great skiplanes.  Just do a nose ski.  Some people even say it is better, as long as you can power the nose off with elevator when manuvering in the snow.

  9. Yamma-Fox added a post in a topic Low Voltage Alarm / Voltmeter for $5   

    Yep, i just snipped the ears off of the voltmeter, "painted" the edges black with a sharpie, and put a dab of Goop silicone glue on the back.  Then stuck it where I wanted it. 
    It is REALLY bright though.  Great for a sunny day, but I'll be trying some layers of tinted plastic over it so I can see out the windshield at night LOL!

  10. Yamma-Fox added a post in a topic YAMAHA RX-1 (140 HP) install in Kitfox 5   

    LOW VOLTAGE ALARM:
    Since the RX-1 ECU needs a power source to keep the engine running, I put in a low voltage alarm in to warn me of any battery / charging problems.
    The low voltage alarm has two leds, green when above threshold, red with loud alarm when below.  Threshold can be set to any value with a smal pot adjuster.
    I put it and a voltmeter into a 2" round instrument hole and set the alarm to 11.5v
    All for only $5
     



     
    As far as buying a motor, I have always thought that getting the whole sled is best.  That opinion is strongly biased since I live in snow country with sleds for sale all around me.  Here are my 3 thoughts for buying an entire sled:
    1.  You can give the motor a little run time, pre-tune it, and make sure it isn't about to throw a rod or something.
    2.  You'll have the following extra components:
    Airbox, oil tank, oil lines, thermostat housing, coolant overflow, coolant hoses, exhaust flanges (flex type), wire harness, ECU, voltage regulator, fuel pumps, starter solenoid, and a few others that I'm forgetting here and will edit in later.
    Some of that stuff you will use, some you will not.  But it is really nice to have a pile of options to work off of and modify to work.
    And 3,  you will have a reference on how all the little things are set up and routed (like carb heat lines, oil lines, ect)  Hopefully this build thread will detail all of that as I go, but there have been times where it has been nice for me to run out to my RX-1 snowmo and peek under the hood as the "cheat sheet"!
    But there is a ton of work parting out a sled!  So if the right deal came up on a motor, you'd just want to make sure you plan some $ to ebay up any missing components that you might need.  And that is a great thing about the Yamaha:  parts are plentiful and cheap!

    Low Voltage Alarm / Voltmeter for $5

    And $5 is in my budget!
    Buy the following 2 items on ebay and make it up for your panel however you want.  I put them both into a 2" round instrument hole and set the alarm to 11.5v

  12. Yamma-Fox added a post in a topic YAMAHA RX-1 (140 HP) install in Kitfox 5   

    I'm not sure what it'll weigh in at....  As I remember, some installs come in around 170-180 with everything.  Mine will be more than that though with a heavier mount and accessories.  I hope it weighs in  25 to 35 lbs less than the subaru did (NSI paperwork puts the fwf subaru at 225lb).  Will report numbers down the road when all my stuff is in there.

  14. Yamma-Fox added a post in a topic Thoughts on mounting full lotus sponsons inboard on a Catalina?   

    Oh and for your destructive testing,  in the lake amphibian the sponsons were under the most stress in side load (while skidding a high speed turn where they could catch a side edge).   They only "sank" when going really slow or while sitting still when wind grabbed the underside of the opposite wing.  Once you get the speed up above 20 mph you had enough aileron to keep em up and also they were skipping along fast enough where it wasn't likely that you could dip one. 
    Bracing for side load will be something I'd look into carefully if I were mounting them up.

    Let an Bing expert shoot me down here, but I've raised needles a little extra by adding an extra nylon washer under the needle clip (in a Mikuni).

    Still sounds like the needle range.  Do you have another needle slot to go?

    Maybe you have the FL instructions?
    Here's a few pages, let me know if you want more.

  18. Yamma-Fox added a post in a topic Thoughts on mounting full lotus sponsons inboard on a Catalina?   

    Just seems like they'd be up too high?
    I have a lot of lake amphibian time, and while taxiing or sittting still you are always resting on one sponson.  If the other wing is too high then the wind can get under it too much and bury the downwind sponson.
    Id say when resting on one sponson, you would want the other one about 16"-20" out of the water, and maybe less if you are inboard like that.

    Come on up someday and ski fly off of the 30,000+ water areas  (many remote with nothing but deer and moose as habitants) and you might see snow in a new light!

  20. Yamma-Fox added a post in a topic Fuel sight tube pics anyone?   

    If you just route your vent line at a careful angle across the tank (from the vent inlet down to the fuel hose outlet) it will serve as a sight guage on one wing as well.  You'll just need to "swag" estimate the fuel level depending on wing angle when the wing is not perfectly level.  
    Either way, you'll know you are getting low if the fuel level in the vent line approaches the fuel hose outlet and could make some calibration marks for the last few gallons at a preset wing angle (like cruise flight and another set of marks when sitting on tailwheel).

    Yeah a little bit of a pita to do that... but I'm sure no one here brought it up because we're worried about you making a reasonable calculated risk and flying around with it. 
    It's because of your co-pilot.

  23. Yamma-Fox added a post in a topic What was i smoking?   

    I really think it looks sweet!  But I think if it were mine I'd probably chicken out a little and take about 10" total stance (4 to 6" per side) out.  
    It is hard to get a good feel for it just looking at the pics, but it seems like narrowing it would reduce leverage and twist potential in all directions....  making it more stout.

    Well...  ya took the vertical load off the seat truss!
    Wonder if it'd handle fore and aft though?
