359.0. "Experience with Bill Evan's Designs?" by LEDS::ZAYAS () Fri Jan 23 1987 14:36

    	Any of you had experience building or modifying a Bill Evan's
    design?  Like the Simitar and Tracer?  Anything (besides CG and
    airfoil section) you would NOT change?

    	Anyone have any flying experience with these guys?  How truly
    fast are these things?  I'm asking because I'm building the Trace
    .40 of his and, given the size and weight, it seems a sporting .25
    should make it haul ass.  As per plans, I've got a .40FSR in it.
    
    	I had to say something!  The notes file has been so quiet of
    late...

359.1words of wisdom...?LEDS::LEWISFri Mar 13 1987 09:594
    Only crazy people believe those things fly with no horizontal stab.
    Can't wait to see that thing "fly", Z.

359.2Eating words of unwisdomLEDS::LEWISTue Jul 14 1987 18:4120
    
    Well, here I eat my words.  The tracer does fly - very well in fact.
    Fred asked me to test fly it last sunday.  The thing has no horizontal
    stab or elevator.  That fact plus the beautiful finishing job Fred
    did on it had me a bit nervous.
    	Well, it took off easily from grass with the OS .40FSR running
    pretty rich.  Flew nicely, a real screamer if you wanted but you could
    also slow it down and it would not do anything nasty.  When we stalled
    it the nose just dropped straight.  I couldn't believe how stable it
    was at such low speeds.  Of course landing was a piece of cake with
    that feature.
    	It looks like a bird when flying overhead with that wide wing
    and narrow tail.  Loops and rolls were the only maneuvers we tried
    so far.  With elevons I'm sure some maneuvers will be interesting.
    I'll let Fred tell you how it performed in an outside loop.  All
    I'll say is that some underwear had to be changed after that one!
    	Congrats Fred, it's a neat airplane!  How could I have doubted
    you?

359.3What...no tail feathersSNOC01::FIELDENWed May 10 1989 01:2119
    Just finished building a Bill Evans Skywalker: three sizes 1/2A
    40 and 60. I built the 40 size but got chicken about the lack of
    tail feathers. So I built a fuselage for slope soaring (agian no
    feathers) and tried it out...my first wing. After putting abot 10ozs
    of lead in the nose to get the balance just aft of the LE it went
    like a dream in 15 knot winds. Roll rate fast but not furious and
    omnly a touch of down through inverted. Bunts are a bit wide but
    loops a tight. Almost imposible to tip stall so Ms etc are ok.
    
    Hod dogs down wind at 50-60 real well. The wing is now back in the
    Skywalker fus with an ST  49 up front  waiting for dry calm conditions.
    Apart from take off and possible ground looping concerns the soaring
    trial suggests she will be a good ship.
    
    Let you know if I end up with a flyer or an instantaneous re-kit
    
    Convert to no tail feathers
