One of my future projects will be to bash a BTE Flyin'King into a twin-engined bird. I want a photo-airplane with an unobstructed nose for a camera and a twin configuration is ideal. Not tomention, this will be a good twin trainer.

See http://www.btemodels.com/ for info in the FK.

Some of my ideas, yea or nay:

1. The FK has a one-piece wing with a flat center wing section and dihedral wingtips. The center section is about 30" in length and each wingtip is about 24" long. I propose a three-piece wing with removable tips for ease of transport. The engines will be placed in nacelles below the wing center section at 10-12" from the center.

Question: how far should the engines be placed from the centerline?

2. I plan to use a pair of Thunder Tiger 46 Pro BB engines (or equivalent 4-strokes) and size the engine nacelles to hold 10-12 ounce fuel tanks. Or I may use small header tanks in the nacelles and a large 20-24 ounce main tank located in a pod at the center of the wing. Or I may mount the tank under the wing so that it fits into the fuse when the wing in bolted on. There should be enough room in the fuse for that.

Question: the plane flies well with a single 90 4-stroke and is designed for a 60-size 2 stroke. I may be able to smaller engines in the 30-36 size range?

3. The FK has flaps in the center wing section and this Twin will retain the flaps even if it means splitting the flap panels on either side of the engine nacelles. I'd like to use slotted flaps, although the linkage will be more complex.

4. I prefer taildraggers and would like to make this a taildragger. Also, as a photo-plane, the nose wheel of tri-gear could interfere with equipment in the nose. But I've not seen many model taildragger twins (although the DH-89 Dragon Rapide was a taildragger twin, and a bipe to boot).

Thanks,
