    As a comparison, the UL260 is 159 lbs. And a little more pricy. Well, maybe a lot more.  Not many used ones out there.

    Oh yeah well the apex setup is so much lower and shorter that I bet it'll fit under many different cowls.   I bet that a short round would need very little if any mod at all.

    Wow, is this the plane that will never be finished?  Well I hope not.  Got back to working on it in the last week or so, firewall, oil cooler, radiator were all done last fall.  Got most of the fuel lines done, and today started laying out and drilling the instrument panel.  Good to see some progress being made.  Forgot the trim indicator light, and trim switch, but they can go to the right of the last row of holes (circuit breakers)  Hope fully I'm not forgetting something else big.  Don't want to do another if I don't have to.  Nice for me to see the progress.  Hopefully it will motivate me to stay at it.  JImChuk

    Thanks for the info Brett.  The guy I'm helping is going with the Apex with Teal's gearbox.  Wonder how much difference that will make from the RX1 with a C gearbox?  I've been trying to find a sideview drawing of the engine and Teal's gearbox, that a person could make a full sized cardboard cut out from to get some idea how far forward, and how high it would be on the plane, and what it would take to put a cowl over it.  No success yet.  JImChuk

    Jim those pre model 5 ones are pretty short.  My buddy with kf4 rx1 had to do a "sleeve ring" for some added length.
    Not a difficult mid, but some extra work.

    Funny you posted this. I was just considering a Jab for my model 2. I am not sure if the Hirth and I are going to become friends. A Jab is currently the only option available at this time. If I can't make friends with the Hirth, then time to part company. Next few days will tell.

    You may have already seen this post from a couple of years ago. At $275/pair, I'm not sure Mike Butts has sold many of his redesigned F7a's . . . but you could ping him to see if the price has improved??

    Jabiru FWF Weight.
    SO before I put my engine back on I thought I would weigh it. With straight pipe Exhaust, Oil, Oil Cooler, Fiberglass ram air ducts and oil cooler ram air duct.  Rotec TBI. total weight is 151.3lbs
    Just in case any body was wondering.

    I generally load any pictures I want to post in to Microsoft paint first, resize it, usually to 30%, then save the smaller file as whatever it was with _small on the end (before the period).  The small size posts much better.

    Chopndrag, I don’t know if you have done much research into the Yamaha motors but you might look at the apex, it seems the weight difference is negligible. The apex has a way bigger following but more importantly more people are stepping up to provide the aviation specific parts for the apex engine.

  16. ChrisBolkan added a post in a topic Tailwheel wiggle   

    I was unable to view the movie in your first post so I don't know what you mean by wiggle.
    if you mean shimmy on landing, Tire pressure, tire wear, castor angle, worn parts, the way the plane is loaded, and all kinds of things can produce shimmy. However, there is only one way to ABSOLUTELY prevent it that I am aware of. That is resistive damping. Meaning enough friction in the back and forth movement of the tire so as to critically dampen any resonance that occurs for any reason. it's a really simple concept and it will always work. Anything else is just moving the resonant frequency around so it is hopefully out of play. And that does seem to work sometimes, but that is like a balloon of shit. You squeeze it somewhere and it just swells up somewhere else. The only way I know to ensure the tailwheel wont shimmy ever is to critically dampen all resonance and that only be done with resistive damping (friction).
    That's my opinion which with $4.00 will get you a mocha at starbucks.

    Wanting to buy Kitfox round cowl
    Hi all.  I may be in the market for a pre model 5 Kitfox round cowl.  In fact, maybe just the front two pieces.  Anybody got any bits and pieces gathering dust?  Thanks,  JImChuk

    Thanks Doug.  My system is pretty much like that.  I did put in a return line.  From checking on line, I found that Rotax says use a .035" opening in the return line.  I took a barbed fitting, drilled into the mouth of it in 4 places at an angle, and then soldered that end solid.  Once it cooled, I pounded the solder in some more in case it had shrunk.  the 4 holes make it impossible for the plug to fall out.  Then I drilled a .043" hole in the solder for the bypass.  Smallest size bit I had.  I am leary of overpressuring the system.  I had issues with my Jabiru when my fuel pump was putting out to much pressure and overpowering the float valve needle.  That lead to one of my dead stick landings...That was with a type 94 Bing which is just a larger version of the type 64 used on the 912.  In talking to the tech guy at Bing, he said those carbs are not meant to have much pressure.  I now run my Jabiru with gravity feed except for takeoff, and I have a feeling I wouldn't need it then either perhaps.  JImChuk

    Five or so years ago I posted a picture with dimensions in the files and forms section when I was building and selling them.  Not interested in building them again but they are easy enough to make.

    My Avid MkIV has this system. I have a 4 psi boost pump, continuously on, in the engine compartment that feeds the engine pneumatic pump, just in case.
