Hangar Flying / Re: So I want to build... BUT
« on: August 21, 2013, 08:50:27 AM »
Hi Jamie

If you join CSA (see the home page on this website) you will get a directory and newsletters.  $30  It is worth it just to get the directory.  Then you can see who lives close to you.  Go visit.  Learn from them.   Some are building.   Some are flying and can give you a ride.
Some are wishing, like you.  There are about 30 so some states don't have a "rep".

Also you will find in the newsletters (around page 18 or so) a list of "state representatives".  Those are particularly helpful and
knowledgeable guys, one for each state.

Hangar Flying / Re: Preferred epoxy
« on: August 11, 2013, 11:08:50 AM »
Hi Whoever you are (it is nice to sign your emails...)

I am NOT recommending anything, in case any lawyers or engineers are looking.   My project was built, almost entirely, before I
bought it.   They were using Ez-Poxy, I think.   The color looks like Ez-Poxy.   If I have to trim anywhere, it smells like Ez-Poxy.

I bought Aeropoxy for the few jobs that I did.   It is a good, structural, epoxy.  I like it.  Smells good.  Others may know of something
better, but I doubt it.

West System epoxy is used TO SMOOTH THE SURFACE.   There is more than one type of hardener depending on the temperature at
the time that you are working or the temp. inside your shop or how much of a hurry you are in.  There may be another type of epoxy carried by G. Brothers that is structural BUT do not confuse the two.   The trouble with West Sys is exotherms.   You mix in SMALL quantities and stir and stir and stir and GET IT ON THE SURFACE AND SPREAD.   You will ruin a few batches before you find out how
to work with it.   Another trouble: all of that stirring puts bubbles in the epoxy which then create pinholes.   Once I had to build a
new aileron (first one was too heavy) and paint it.   The paint company recommended cleaning with a certain product and it is a
good organic solvent.  It went right through the pinholes and destroyed the foam underneath.    :'(   Had to build another one.

Matt:

When Bill James says "cool wx" he means below 100 degrees  <grin>.     Well, maybe Fort Worth, TX is not THAT hot but I
have seen some warm days in north TX.   Not like cool wx in Minnesota......   I have lived near the interstate both east and
west of him by 50-150 miles.

I still think you were using the wrong ratio of hardener/epoxy.   No wonder it did not work for you.

I never used those pumps; most of the structure was built when I bought the project so I weighed everything (in the CORRECT ratio).

Hi Joe

Nobody has answered this email so I suggest that you try putting it on    canard-aviators@yahoogroups.   com
There are about 10 times as many canard guys on it.   Maybe someone will have a suggestion.

First, Your posting is confusing.   Did you REALLY use West System pumps for Aeropoxy?   Your ratios would be wrong.
That is VERY dangerous.   You need to get some help AT YOUR SHOP, not on line.   Find someone who is an expert to
come over, share a beer, and SHOW YOU.

Second, try posting on canard-aviators@yahoogroups.com   I think there are MANY more people that use it.   Some are
expert.   I am NOT.

Third, anyone building or thinking of building should be in CSA.  See the home page of this website.  That is how to find people
to come to your shop and help.   It costs $30/year.    Iff that s too much, try building model airplanes.

Yes, I have had the amine blush as you described.

I believe D. Kreidel said "DON'T DO IT" very well.   Just a little addition:  The CG would be VERY different if you used a Rontz instead of the original canard.   And you would have no idea where the correct CG range might be.  We have had a few deep stalls in canards that were built correctly but someone still got the CG wrong (due to the way the aircraft was loaded ON THAT PARTICULAR DAY!)    Now you are thinking of changing a design in spite of the designer's stated "DON'T.

IF you try to use the Roncz, your friends will witness a pile of broken airplane.   You will not be a witness....

Hangar Flying / Spread sheet and CG
« on: July 18, 2013, 05:19:35 PM »
Hi group

Our EAA chapter (326) has very accurate scales for members.
I feel comfortable with my project's CG but I am still
going to do the weighing and calculation again.  I bought
a new battery which is lighter but can slide forward
another 3/4".  So I don't expect a lot of change.  It
is time to do a condition inspection so new calculations
will be better, IMHO.   

I am planning to do it with a known quantity of gasoline
in each tanks.  I have done the weighing with the tanks
empty before; does not seem reasonable to drain all the
gas as the tanks are so close to the CG and there is
some hazard in draining tanks. 

Someone gave me a copy of a spread sheet program but
it is in an old computer.  The old one had a small
problem anyway.

I think it is time I buy one.  How do I do that?   I don't
have spread sheet software.

Thank you for any comments.

Well, Arlington is over.  We had about 12 or 14 canards.  I did not count.

Thanks to Joe Person, Dale Martin, and others for the meal.

The weather was GREAT.  Best year I have seen for 12 years.

Attendance was down last year and down more this year.

The military guys did a very good job with "Camp Davis" but not many airplanes.   The P-51 put on a great show.

The auto club a had VERY good display of cars.

Hi Waldo

Thank you VERY much.   I hope it happens.  Looks like a big "IF".   Your message is a bit unclear.

I am begging for a ride to wherever we eat.   I have never been to one of those dinners.   I have seen the Bremerton area from the air (from a C-152) and been to the restaurant (by car).   I pay for gas, oil, etc.   Please, someone...

I believe many canards will be there.   I will be there in my motorhome.  Please come by after 5 PM.  Look for 308VWB and I will have some of your favorite beverage on hand.   Hopefully it will be cold but I have not checked the refrigerator yet......   My parking space  usually is the 5th row back from the taxiway (where the aerobatic planes are parked) and about 12 spaces from the fence that separates the camping from other activities.  I generally arrive before most canards and stay after all have left on the weekend.  My wife and I
need the extra rest before hitting I-5 freeway.
