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...

Only crazy people believe those things fly with no horizontal stab.
Can't wait to see that thing "fly", Z.

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?

| 359.3 | What...no tail feathers | SNOC01::FIELDEN | Wed May 10 1989 00:21 | 19 | |
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
