110% Anderson Pylon

 I made some progress on Jack’s Andersen Pylon, even worked on the pylon mount a bit.

Got the Saddle area for the pylon mounting sheeted.

Then installed the servos, pushrods using Sullivan Gold N cable hooked up the elevator and rudder, and lastly the compartment for Motor Battery, ESC and Receiver/servo batteries.

 

What’s left is the Pylon and some finish work at the Horizontal stab to fuselage junction.

110% Anderson Pylon

 








I got the landing gear made of 3/16 hard music wire made and mounted it and the motor to the fuselage.

The motor mount is made up of a lamination of 3/8 aircraft plywood back plate with v groove milled into it for landing gear,

Then a 3/16 aircraft plywood plate over that with the back plate of the motor mount then over that.

All held in place with hardened 6-32 Allen cap screws.

The motor mount back plate is strengthened to the fuselage with plywood gussets and then at the joint

It is covered at the joint with 8 oz. fiberglass tape.

 

The motor has a 13.5” clearance over the ground to minimize ground strikes.

 

Next the pylon!!!!!!!!!!!!!!!!!!!!!

110% Anderson Pylon

 Tail mounted...











110% Anderson Pylons built from Klarich Kits at the 2001 SAM Champs/Vegas
The blue and yellow one was by Jim Kincy of CA. I don't know who built the one with the orange flames.  Both were flown in Glow Antique.  Long motor runs call for BIG models!

110% Anderson Pylon

 I also got the sides joined on the Andersen Pylon today..

Had to work fast with making first both sides and then before the longerons which had soaked in Windex for two days due to their high density and then the sides were joined together

With no strain and will hold that form as they dry.

Notice that the rear part of the longerons are also 3/8” sq Spruce and that the highly curved front 1/3 is very hard balsa.

Also put large gussets holding the front pieces where the landing gear and motor will be mounted.

 Started building the fuselage sides, both sides built after first cutting all the verticals.









Late Dale Hannum's Anderson Pylon

OS FS-60 converted to ignition

Dale Hannum maintained the Model Recognition page on the SAM  Website. https://antiquemodeler-old.hrncar.work/approved_lists/adl-gas/gas_list_index.html
Appears to be covered in either Solartex or SIG Koverall

110% Anderson Pylon

 Getting ready to build the fuselage sides. Plans laid out and double layer of wax paper in place.

Fuselage verticals are all cut already and sanded to same length and angles, I find it far more accurate on this type of fuselage build from experience on Lazo Bomber builds.

Longerons are soaking in straight Windex for a day or two to make the bend at the front of the fuselage.  Hard 3/8 balsa longerons won’t make the bend without steaming or soaking.

I hope that after the side are built it will stay flexible enough to make the same bend when I join the built sides.

 

Also capped with 1/16 ply the root ribs of each wing half and sanded them to conform to the end ribs.

 I’ve been criticized for having too clean of a shop.

 

Here’s proof of my building and balsa shaving!

 

By the way,  that’s probably $20 worth of balsa on the floor…..in shavings and dust…..

Just need to make the root rib Plywood 1/16” cap ribs and put on the cap strips.

 

Also note the $20 worth of balsa shavings on the floor!

110% Anderson Pylon (joining the wing tips)

 I got the wing tips joined to the center on your Andersen Pylon……….

Have to put the transition ribs in and sheet the wing next.   The ribs as they are cut really have created problems.

I am cussing this model a lot, won’t be building another one of these.

I wonder if Jim O’Reilly drew and Holman cut a version of this model?

Jay:

Holman has the plans and short kit for the original 90-inch version.  I think this is what Glen used for his build.
  
You are doing a great job.  Thanks.

No, O'Reilly didn't draw this model and the kit from Holman uses the same John Pond plan.   I suspect he did a better job plotting the ribs.  There is a nice 50% Anderson Pylon plan on Outerzone.  Perhaps, doubling this one would be a better idea.
