378.0. "hot flying scale and engine sizing" by IOALOT::SYSTEM (Any R/C's in Westminster?) Mon Nov 30 1987 10:19

    Hi Just bought my Winter project.. and was wondering if anybody
    else has built one... and would like to here comments on it
    like how hard is it to build,   
    
       its a SIG 450 MUSTANG, and i'll be putting a .45 k&b in it. 
    i should receive the engine and the plane by wednesday this week
    I'm very excited about it.    but in the brief description in the
    add it did mention alot about glassing?
    
    
    thanks in advance.

    Boy!!!! I hope you're an experienced low wing pilot!!!
    
    This design was originally a Formula 1 race plane. 
    The wing thickness at the root is about 3/4 of an inch and
    if I remember correctly the thickness at the tips was about 
    1/4 of an inch. I think the .45 K&B will be to much engine
    for this plane. You may want to consider fiberglassing the
    wing to add some strength.  GOOD LUCK!!

378.2GO FOR IT !TRCA03::MARQUESWed Dec 02 1987 16:5224
    Hi, there!
    
    I have a different opinion from Tom.
    
    I started flying RC in May 87 and had a - pardon the expression
    - SIG kadet. What a clunker. Then I was talked into another trainer.
    It is not a clunker but is absolutely no fun to fly at all.
    Well, I says, enough of other people's opinions. I'm gonna buy meself
    a patternship. WHAT A DIFFERENCE! Low wing, no dihedro, quick roll,
    overpowered. It's a dream. It flies like an agel, only faster!
    I was told all kinds of things about "low wings are much harder",
    "tapered wings will snap-roll on you","no dihedro is too unstable"
    and all kinds of expert advise. Know what? All horse-feathers.
    The thing goes where I want it to go. It doesn't snap unless I tell
    it to, and the extra power really makes is so much mode enjoyable!
    And personally, I find it much easier to fly thand those
    sluggish-have-a-of-their-own flat bottom high wings. Enjoy her!
    
    Fern
    
    P.S. All the experts wanted to convince me I could not fly a Cap21
    because of the same reasons. Well, they were wrong. I not only fly
    mine very well, I think it is easier than any flat bottom high wing.
    And of course, the flying is so superior it is not funny...

    All I said was that If chris was of limited experience, that this
    plane would be a handfull.  The skooter, Kouger and the skyleader
    are great ships.  We're talking 4-5.5 lbs ships with 500 to 560
    squares of wing. The Mustang 450 will be  5 lbs of rocket ship
    of 450 squares of wing.  It can be fun, it will be hot. I had one.
    I had a supertiger rear exhaust .40 in it. It was hot and hiper.
    Not smooth like a pattern ship. 
    Just be careful. You will have your hands full.Try and keep it light.

     1 Change to my original note, I've recieved the engine, k&b .45
    sportster, nice engine (why is it considerably bigger than my o.s
    .40?) the engine i bought from CIRCUS HOBBIES. The 450 Mustang i
    had on order thru SHELDONS HOBBIE, well after having the motor
    for 1 week i kinda got concerned that the kit hadn't arrived since
    i ordered them the same day, SO I called SHELDONS friday night
    to see if there was a problem. and there was the mustang was on
    backorder  should get in stock within 4 weeks (unexceptable) so
    i canceled and changed my order to the kouger mkII (yes i made sure
    they had it in stock) so I`M a bit excited about it, and too Tom
    no I'm not experianced in flying but i have two trainers all
    ready no need for a third , and i have to build again 
    the way the weathers been I won't see any flying for a while (to
    windy)  .

378.6GOOD MOVE, DAVE........GHANI::CASEYATHE DESERT RAT (I-RC-AV8)Mon Dec 07 1987 10:4416
    Dave,
    
    I wasn't gonna chime in with my thoughts/concerns on the subject 
    of the Mustang 450 as Tom had already covered them pretty well but
    I think the decision to go to the Kougar instead was a good [wise]
    one if, as you've admitted, yer' still in the early stages of learning
    to fly.  The Kougar with the .45 should be a good combo but be sure
    to get lots of expert help while learning to handle it.
    
    BTW, I think the reason most .45's are so much larger than .40's
    is that .40's have been evolved from .29/.35 crankcases and .45
    is just more than they can punch them out to.  Therefore, .45-thru-.50
    sizes share similar size cases while .60 takes another increase
    in case size. 
    
    Adios,	Al

    re .-1 & .45 sizes: FOX is the exception here. Their .45s are identical
    is exterior dimesion & weight as their .40s.

    Dave,
    
    O.S. 40's and 45/46's have the same crankcase dimensions (I checked).
    Glad to hear you changed to the Kougar, the M 450 looks very difficult
    to fly to me (very short wings).   My Kougar is coming along.  Over
    this weekend I got the Fuse built,shaped,and tail feathers and turtle
    deck installed.  Also got the 1st coat of primer on the wing.  It's
    starting to take shape.  Also, buy lots of sandpaper! You'll see
    what I mean when it comes time to shaping the fuse.  G' luck!
