Wow! You need a license to fly fun-fly???

Well theres the GT Generix Fly Rod.. I only mention it because it used to 
be kitted by a good friend of mine, Doc Passen. Theres also a foamie he 
calls Cheap Sensation.
|I have been lucky enough to fly a wide assortment of fun-fly machines

Well they aren't exacly different or new.. just your typical sticks-and-
FasCal fun fly planks...but they impressed the heck out of me at the Mun-
cie Grand Opening. Never did see one of these things fly before. More 
like a leaf with a rocket attached than anything else.

    I just finished up building a new YARD DART. I am going to go-it the hard
    way, "no-computer radio". I built this one differently, it weighs in at 
    3.75 pounds which would normally be considered heavy; except I put a
    shiny new SAITO .50 four stroke on the front. I'll be test flying it this
    weekend, if the weather holds up. I'm planning on adding a Christy-Mixer
    for flaperons this evening. Except for dual rates that's all the fancy 
    stuff I am going to use on it. No differential throws, air brake mixing,
    rudder mixing, et cetera. It will be different. But what the heck it's
    all for fun. I wanted it for real fun flying not that serious contest
    stuff.

    The SAITO .50 four cycle is a pretty potent engine. It is a bored out
    .45 and actually weighs less than it's smaller 45 cousin. While doing
    my initial bench run break-in, it shows real promise. After a few tanks
    on the bench it'll hold a 12-6 APC prop at 10,100 RPM with no trouble.
    The only thing I don't like about it is the carburator is a two needle
    design and it has a real rich spot at about 1/2 open throttle setting. As
    you advance the throttle real slowly from idle to full speed, when you
    pass through this spot the engine quickly goes real rich and slows way
    down, then as you continue to increase throttle, it goes away as the
    engine picks up speed again. Looking at the carb shows it to be a standard
    two needle design with no taper to the needles. At the mid way point the
    main needle opens and starts to take over from the idle jet causing the
    rich spot. Since you fly a fun-fly at low speeds it may be a problem, 
    but I'll find out this weekend.

"Yes", replied Obi Wan, "I was a DOS programmer. But that was before the dark
