Indoor Flying.

I fly my indoor models with the Ottawa Indoor Model Flyers, in Ottawa, Canada.

Flying is on Monday Nights 7-9 pm at the Woodroofe High School from mid-Sept to mid-May, with the exception of holidays. Come out and watch or join in. Everyone in the club is more than eager to help a newcomer.

NEW: Freeflight Plans

Here is my fleet of indoor models:

---

Cessna 180 This plane is from the plans on Paul and Ralph Bradley's site www.parmodels.com The model can be put together very quickly. The model is obviously well designed and was flying well after minutes of trimmming. Changes I made to the plans were a nose block that slides into the fuselage and the use of 1/32 balse for the wing wingspan: 52 cm weight: 11 g power: 2 strands of 1/8 inch design: John Cooper built: 2007 -----------------------

---

Fiat CR42 This No-Cal plane features a motor stick made from rolled 1/32 balsa tube. The complex camoflage and markings were printed on white domestic tissue via an injet printer. The model is light and seems like it should fly well, but I am still having problems getting it trimmed. wingspan: 16 inch weight: 11g without rubber power: 1 strand of 1/8 inch design: John Cooper built: 2007 -----------------------

---

Curtis F9C-2 Sparrowhawk This is my heaviest indoor freeflight plane, despite my effort to lower the weight of the kit. I substituted 1/32 balsa for the rear half of the fuselage and many wings ribs. The plane has removable wings; the upper wing, via slots and the lower wing via balsa spars in paper tubes. Despite its weight the plane is a stable flyer, although a little fast wingspan: 76.2 cm weight: 102g power: 2 strand of 1/4 inch design: Dumas built: 2007 -----------------------

---

Breguet 14 This is an all balsa sheet model, inspired by the plans on Paul and Ralph Bradley's site. It is a stable flyer but needs more work to get more altitude and more duraction. wingspan: 44.5 cm weight: 19.5g power: 2 strands of 1/8 inch design: John Cooper built: 2007 -----------------------

---

Morane Saulnier A1 This plane is build from a Dare kit. The kit is clearly high quality and intended for experienced modellers. I have started to trim it indoors, but had numerous heavy landings. I am going to complete trimming outside in tall grass. wingspan: 73.9 cm weight: 72 g power: 2 strands of 1/4 inch design: Dare built: 2007 -----------------------

---

Guillows Lancer Another outdoor model, flying happily indoors, the Lancer is an excellent beginners plane and an excellent flyer. At about US$ 9.00, the kit is great value and I was surprised at the quality of the wood, die cutting and the plans. I made several minor changes to the model, but I believe the model will fly nicely if built unmodified. The only real weakness of the model is the landing gear; it will break after the first few flights. I would suggest leaving it off, or, as I did, replace it with bent wire. I used one piece of wire with about 3cm sandwiched between balsa and glued between the longerons on the bottom of the fuselage. wingspan: 61 cm weight: 25 g power: 1 stands of 1/4 inch design: Guillows kit (modified) built: 2006 -----------------------

---

Vought F4U4 Corsair At 98g, the Corsair is pushing the limits of what can fly indoors. None the less, the fighter flies in very stable circles, although quite fast. The plane was mostly a stock build of a Herr kit. The well fitting, laser cut parts made it very enjoyable and quick to put the frame together. The major modifications were a removable wing, and a large flap on the port wing to counteract the torque. wingspan: 76 cm weight: 98 g power: 2 stands of 1/4 inch design: Herr kit (modified) built: 1999 -----------------------

---

Fairey Firefly MkII The Firefly is built from Lubomir Koutny's beautifully rendered plans. I modified the plans to use fewer stringers and fewer wing ribs. The plans include no written instructions but are very detailed and accurate. The model flys quite well and really needs more space than an indoor gym has. I originally started with a 3 blade balsa prop but had to switch to a 9.5 inch Peck because the blades were always breaking on landing. Plans can be bought from Mike Woodhouse here: www.freeflightsupplies.co.uk wingspan: 71 cm weight: 51 g power: 2 stands of 1/4 inch design: Lubomir Koutny (modified) built: 2006 -----------------------

---

Lockspeiser LDA-01 Another Walt Mooney plan, the plane is still in the trimming phase. Unlike most models, the issue with this plane was being too nose heavy because of the short moment of the rear cowl. Typical of canard models, it will not stall - it just slows down and descends. wingspan: 13 inch weight: ~12 g power: 1 strand of .080 inch design: Walt Mooney built: 2006 -----------------------

---

Morane Saulnier MS225 This is probaly my best flying peanut model. It is covered with light domestic tissue. Domestic tissue has advantages for this size of model. It is more opaque than Japanese tissue and is far less likely to cause warping. wingspan: 13 inch weight: ~11 g power: 1 strand of .080 inch design: John Cooper built: 2005 -----------------------

---

Dehavilland Canada DHC-5 This plane has alot of potential and is capable of long flights. It has, however, one major problem - its flight path is random. This makes indoor flying difficult as it constantly runs into walls. The issue is that large lengths of rubber in the nacelles bunch up so that thrust is inconsistent. wingspan: 51 cm weight: ~20 g power: 2 strand of .080 inch design: John Cooper built: 2005 -----------------------

---

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. 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 -----------------------
