Monocoupe 110 The Monocoupe took a little longer to get trimmed because the original 5 inch peck prop was causing too much torque for the small wingspan. I trimmed the prop and was able to some good flights, although not the ceiling grazing that most of my other peanuts can do. Video wingspan: 12 inch weight: ~12 g power: 1 strand of .080 inch design: Walt Mooney built: 2005 -----------------------

Parkshark Designed more as an outdoor plane, the Parkshark can still get some very good flights indoors. It is designed to be very portable and disassembles to fit in a small foam core box. wingspan: 16 inch weight: ~20 g power: 2 strands of 1/8 inch design: John Cooper built: 2005 -----------------------

Jodel D120 The Jodel D120 (yet another Walt Mooney peanut). The large polyhedral angle of the wings makes the plane quite stable. It is a good and consistent flyer. wingspan: 13 inch weight: ~10 g power: 1 strand of .080 inch design: Walt Mooney built: 2005 -----------------------

Bede BD4 The Bede BD-4 is built from another excellent Walt Mooney Peanut plan. I wanted to put a big prop on the plane so I needed to extend the landing gear well beyond the scale size. The plane flew well, almost touching the gym celiing on its first few flights. wingspan: 13 inch weight: ~5 g power: 1 strand of .080 inch design: Walt Mooney built: 2005 -----------------------

Halberstadt CL2 All coloring and insignia on this plane are done with an ink jet printer on white Japanese tissue. This approach cuts down the finishing effort significantly. Still in the trimming stage, this model shows alot of potential. wingspan: 38 cm weight: ~8 g power: 1 strand of 1/8 inch design: Claude Powell (modified) built: 2005 -----------------------

Bucker Jungmeister The Jungmiester is my best flyer. From ROG it can consistently obtain flights over a minute. It is covered with Risteen top and bottom. The markings are Solite and black Risteen. Note that Risteen markings on Risteen work very well - it was easy to get good edges with no bubbles. Video wingspan: 45 cm weight: ~10 g power: 1 strand of 1/8 inch design: ? built: 2004 -----------------------

DeHavilland DH.85 Leopard Moth The Leopard Moth is built from a Easy Build Kit. I made many changes to make the plane lighter and more scale looking. The Fuselage and rudder are covered in Japanese Tissue; everything else is covered top and bottom with Risteen. The plane has flown well, but not consistently. It needs more work trimming.  Video wingspan: 56 cm weight: ~15 g power: 1 strand of 1/8 inch design: Easy Build Kit (modified) built: 2004 -----------------------

Comte AC12 The Comte AC12 is built from a Walt Mooney's plan. This plan is one of the best, I have seen. I didn't change anything. The model is covered with silver Risteen. Despite having almost no dihedral and being a peanut, the model is quite stable and a good flyer. wingspan: 13 inch weight: ~5 g power: 1 strand of .090 inch design: Walt Mooney built: 2004 -----------------------

---

Fokker E1 The Fokker E1 is covered with Japanese Tissue dyed with Earl Grey tea. This gives it a much lighter and more beige color than would be had with Orance Peko. The machine gun weighs about .2 g and is made from black tissue layered on tracing paper. With the tissue flat I cut out the numerous air vents and then rolled the paper and plugged it with small disks of styrofoam. wingspan: 41 cm weight: ~10 g power: 1 strands of 1/8 inch design: John Cooper built: 2003 -----------------------

---

Lockheed Air Express The Air Express was built from a Dumas Kit. I redesigned the wing to make it lighter and thinner and flat bottom. I replaced the heavy Guillow's type wheels with ones turned from contest balsa. The wings are attached with rubber bands. The plane flies quite well. Video wingspan: 76 cm weight: ~58g power: 2 strands of 3/8 inch design: Dumas Kit (modified) built: 2003 -----------------------
