Just got word down the chain of Al's health downturn.   His wife Norma shared with Bob that he's had and incident that has effected his speech, mental activity and arm.  The doctors diagnose him with "Altered Mental Status",  the other doctor diagnosed him with "Acute Vascular Dimentia".  We'd like to ask our members to remember Norma and Al in their thought and prayers.

Thanks for your comment, Tom.  The polyhedral wing is also our favorite.  We're planning to put a longer polyhedral wing on a future version of the Droop Snoot.

Sweet...I like both wings but am partial to the polyhedral wing with the raised tips!!

Thanks, Bob, I kinda like it, also.  I'm planning to build a version II pretty soon.  Here are a few flight pix.  The first is with its original wing.  The other two are with the Berkeley Powerhouse wing.

The fuselage bottom is covered and Droop Snoot is ready to fly with more droop. Smiley

Al, I like the shape of this fuselage. Cannot wait to see it finished and in flight.

The cutting operation went well.  Only needed a bit of sanding to smooth of some rough edges.  Now to glue a bit of tissue to cover the bottom of the fuselage.

After flying Droop Snoot with the 020 in the nose we kinda liked the illusion of flying a model from a long time ago.  However, the models flight pattern was not as smooth as before.  The 020 installation did not have the weight that had been used before.

Rather than add more weight to the nose, we decided to remove some weight from the rear of the model, and see what would happen.  We selected an area shown by the red line and cut it off with a fine tooth saw.

Hi Al.  Thanks so much for all the video links and stories.  Very educational.  You obviously had a lot of fun in your life with aeromodelling.  It really cleared up a lot for me.   Smiley Now I know that half A size is .049 cu in, and quarter A size is .020 cu in engine.    Undecided    The article about the intro of the .020 engine stated that it had a lot of power.  I built a 30" Aeronca and put that .020 engine in it for U Control (Ukie), and the other kids in our Gr 9 Model Flying Club in High School said it would never fly - but IT DID !!!   Wink    I also made a twin hull Catamaran boat with two Cox .049 pusher props and SHE really went!   You really have a great collection of little engines there.   Again thanks for all the videos - great loops by the way!  And Happy Flying!

Thank you, Richard, Ian, Tom, for your kind posts.  Excuse us for not responding to them earlier,  we're having nice warmer weather so we've been busy with yard work and other tasks and have neglected to keep up with the posts here. 

To answer your questions, Richard, although the models have a Cox 020 attached to the nose.  It is not used as power for the model.  It is simply a nose weight to help in the balance the model.  However, it does have the appearance of Ukie model in flilght.   

In the Control Line section of this forum, I have a thread  about QuarterA Ukies which explains more about this form of model
http://www.stickandtissue.com/cgi-bin/yabb2/YaBB.pl?num=1471843717/0

Thank you,Tom, for posting video of my flying the Delta Dart.  In this flight the swing pole is pointed upwards and swung so that the model flies in circles above my head.  In another flight pattern the model is swung into the air and the pole is extended in front of me close to parallel with the ground and the pole tip  is moved in small circles.  This causes the model  to fly in a circular path in front of me.  Using a swing line shorter than the swing pole, contact is avoided between the swinger and the model when the models path comes close to the swinger.  This video shows a flight in this manner.

Here are a couple of videos with me turning in circles with the model.  We very rarely do this any more, at a  ripe ole age of 78, we try not to engage in risky behavior that could cause a fall Smiley

Hope this answers your questions.

Hi Al - I mean the bigger tether flyers with engines.  "How much fuel do you put in them and how long, and how many laps, do they fly for ?"  I haven't flown a fuel engine model in 46 years.   Smiley  I guess you just fly until the fuel runs out ...  Do you have a link to a couple of videos?

This is one of Al's videos previously posted:  https://www.youtube.com/watch?v=JnT2nA6NO9g&feature=youtu.be ;  of him flying a delta dart.

Dizzy is right Ian.  My record at 15 yrs old in my High School Flying Club after school is 46 laps.   Roll Eyes

Well, since you are turning in a circle, it isn't too healthy to take on too much (alcohol-based) fuel because you get dizzy enough just keeping the plane in the air without extra help.  Grin

Al - I have a dumb question - how much fuel do you put in them and how long, and how many laps, do they fly for ?
