Had a failed flight on the maiden day, just before Thanksgiving day 2014.
The plane flew away from me and was lost for about a month until Christmas eve 2014, when someone called me telling they found the plane.
The biplane was rebuilt and painted, and due to bad weather and other things, could not fly it again until recently.
It was re-maiden-ed , and now in the second week of its new life.
Foam wings, from 54" chuck glider, added ailerons, with two 9g servos under the wings.
Coroplast vertical stabilizer.
Wing Span = 54"
Wing Area = 405 sq in = 2.81 sq ft
AUW = 20 oz
wing loading = 7.11 oz/sq ft
motor super tigre 370 brush less , 20 A ESC
9x6 APC propeller (used GWS 8x4.3 for the maiden flight, a bit anemic for my taste, the plane invites more power and speed)
3S 1000 mAh LiPo battery
CG location : 2.25" from wing leading edge at the root.
This story started like this:
Danny gave me as a gift, a Radian fuselage (thanks Danny !).
This fuse had a previous life as an FPV platform, with a power pod, pusher style, above and behind the wing trailing edge.
Dremel tool in hand, the pod was cut off.
I purchased a brand new set of wings and horizontal stabilizer from my LHS, 15 mi away ( HobbyTown, $44 total).
I used a 70 g brush less motor ( no data on make, model, specs), an equally unspecified ESC (I guess 30 A from its size...) , 2200 mAh 3S 25C Lipo battery , and a HK Super Kinetic folding propeller. Link to the HK folding propeller: Super_Kinetic_Prop
The motor was mounted in a non standard fashion , with the motor outside and ahead of of the Radian motor mount.
The motor current draw was 21 A at full throttle, on a bench static test.
The fuselage was covered with clear scotch heavy duty packing tape , which I shrunk with a sealing iron. This gave a lot of strength to the wobbly fuse...
Similar treatment with clear tape was applied to the wings, albeit not covering them completely, mostly the leading edge and the wing roots.
A couple of pictures are attached to this post showing the plane.
A roundel sticker for a HZ Corsair was placed under the right wing, three brown packing tape bars under the left one.

This is my High Wing pusher - 54" wing span Chuck Glider conversion project.
This is the first concept, as built and flown a year ago.
It is based on the wing taken from the "ULTRA Flyer" foamie , available at HobbyTown for $8.
The 54" wing was reinforced with bamboo skewers and strapping tape.
The wing area was extended with the addition of fixed ailerons (which became true ailerons in the second version , the last picture attached below shows the version No 1.1 , with the ailerons implemented ).
The fuselage was made from 1 1/2" foam , scavenged from packaging material. You may see plenty of use of packing tape and gorilla glue.
The motor is a turnigy 2217-16 , link to 2217-16 , 3S , 20 A , 73g , Kv=1050 RPM / V , turning propellers in sizes from 9x6 to 10x4.7.
The servos are turnigy 9 gram , plastic gear type.
The battery is a 2200 mAh, 3s, 30C, weight =200 g =7.07 oz..
