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.

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 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! |
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.
