1500 square inch Anderson Pylon

I took my simple point and shoot camera (2meg. pix - 20yrs old) out to the field for some quick shots.

Have one in the distance flying.
Others are of me ( Meaghan) holding the plane and one of Jack in his chair with the plane.

Jack can fill you in on the flying/ handling of the plane.

Meaghan McIntyre






Folks,
 
Yes, I flew the big Andersen Pylon this morning early at the sod farm.  Meaghan and Glen present and helped.  Perfect weather for first flights.  I made four flights.  Light wind and sunny sky.
 
The four flights ranged from 11:34 to just under 13 minutes.  I was hoping for 20-minute flights.  And the take offs were rather long.  10 cell 2500 mAh Ni-Cd motor battery.  Neu 1107/6D geared 6.7 with Falcon 21/14 CF prop.
 
I figured this power train would handle the 1520 sq. in. Andersen Pylon at the 9 pounds needed with the big Ni-Cd motor pack.  After the four flights we weighed the model with batteries and to my surprised total weight was 11 pounds 6 ounces.  That is a wing loading of 17.24 ounces per square foot.
 
At 11 pounds 6 ounces I could use a 4S2200 mAh Lipo motor pack.  I wonder what kind of flight times I would get with this size Lipo?  Maybe Jay can run the numbers on this change?  Would it be worth it to go with this size Lipo motor battery?
 
It is a nice handling model.  Also, glide is much better than I would have thought at that weight.  Just need to get flight times to 20 minutes early mornings.  If that is possible?

Jack,


I can't run ECALC,  my computer crashed a couple of weeks ago and the disc is toast.
I won't be able to do tasks like that until I get a new computer and just haven't been able to to do so with other stuff happening. Plus I need to get the $$ together to make the new computer.
My old computer was about 20 years old.

Sorry,
Jay
