Dave Cook has some great thoughts on judging, and judging the computers of today....

As I recall, he advocated tossing the high and low judges' score per maneuver when more than three were used...

He has some cool ideas, although a bit contrary....


  Tossing out high/low is never a good idea, it operates on the presumption that there is a correct score. It will automatically toss out judges that run "high" or "low" normally, whether they are doing a good job or not.  Buffalano's method (which involves normalizing the scores first, and is very similar to the methods I used to evaluate some previous results) solves this issue but has the fatal flaw of having to wait until all the scores are available. This method is more-or-less doing the same tracking method used to select judges like we have already done, but looks at an entire round and then excludes them for that round itself, at which point the others are used.

   Again, this might work for Top 20 and Top 5, but there aren't going to ever be enough judges per circle to do it for qualifying. And, when I have taken individual sets of results and applied various methods, it never once changed the winner, and it only occasionally changed any of the placements by one or two.

   If you process the scores with 3-4-5 different methods, and they all yield the same results, it tells you that all the fiddling or tweaking with format and processing is more-or-less irrelevant, AND, that you should probably choose the simplest version.

Hi, Guys - thanks for the compliments.

The lines, plane and handle measure out to 69 1/2 feet, fuselage to handle center line.
The pull is actually not that bad - no more than a Cardinal or Strega.

As soon as practical, I will install three SAITO 30s as I prefer them to the Surpass engines.
Also, I designed the plane such that it can easily convert to a taildragger. That should shift the CG back a bit since since it is noseheavy.
The dry weight, by the way, is just over 80 ounces.

As of right now, it has half-span flaps. In about five minutes, I can convert to full-span.

Robert - how to I accomplish the "share" feature?
Thanks for the info,

I think this is the button you're refering to?

Watching that flight, as I stated on another post, you have me beat.  I would over all put you in the upper 300 to lower 400 range of score.   It still needs work and you are getting there.   You might print off some of the critic sheets that are on here somewhere and use them.  Of course you have a great group of people to fly with. 

My flying buddy and I tried those critique sheets, and we quickly went to just watching each other fly, remembering the worst two or three things, and then debriefing right after each flight.

Of course, at it turns out we each have our own screw ups that we do over and over again, so the conversations have gotten short, and involve the word "usual" a lot.

James,
I am curious about the reasoning behind the downthrust and the positive stab incidence.

62" span, 675 sq in, Evolution 60 with LMS custom venturi ( what else..!), Scott Dinger custom muffler.
Sig Champion 10% fuel, 12 3/4 x 4 1/2 CF prop - Bob McDonald/ Billy Werwage design, 65' 6" lines.  5.7 sec lap time
1 1/2 deg down thrust and some positive incidence in the stab  ( thank you Bob Whitely!)
molded  balsa fuselage
and it weighs way tooo much....

James,

Really nice model!

I think all of us have this thing for aircraft of the Golden Era, I know I do.

Can you do a run down on your model? Basic info.

It's large, do you fly in on 70' lines?

Inspiring to say the least.

I do not think you will ever see more than 3 per circle until Saturday used, and dumping the high and low judge, or some of their scores is the wrong thing to do, many times you are dumping the best , most consistent judge, and keeping the one who is bracketing.

What does judging the computers mean? and what does that have do to with judges scoring a stunt contest? computers just do whatever they are told to do, and calculate really fast.

Thanks, guys. I'm fixing a problem with the motor mount that cropped up. Not a big deal but it will take a bit of time. Still hope to have it ready to fly this weekend.

Hey, can I design sexy or what?
