Canard Center Of Balance!!!!!
I was just wondering exactly how do you calculate the balance point on a swepped wing canard. I have had this idea rolling around in the ole' cranial cavity, that I would like to build a canard, just for the heck of it. I was thinking about something electric powered, pusher. Me and TurboCad have already been rough draftinging it. TurboCad is the best 20 bucks I ever spent. I even designed a flower garden for my wife, "who I might add is the best wife in the world". I stay at home looking after 2 of our small sons, while she gos to work. I was injured when I fell Off A Motor Grader at work, I'm A heavy Equipment Mechanic, messed my back up really bad. She let's me build airplanes, as long as I keep the house clean, not a bad deal. My Boys love airplanes to, If the balsa and glue are flowing there they are, like my shadows. I hope that they will continue this fantastic hobby. Maybe it will keep them from some of lifes darker elements. I'm lucky because I have a flying field in my front Yard 200' Wide 1200' long all centipede grass, it was an old tobacco farm.

Probably the simplest option and one that your boys will like the best is to make a little 14 to 16 inch all balsa test glider and play with it. You're looking for a CG and corresponding elevator trim that provides a nice glide but when thrown harder results in a gentle pull up to a stall. If it tucks and lawn darts itself then it's too far back and not enough up trim. If it pulls up sharply into a tight loop then it's too far forward with too much up trim. You're looking for the happy medium just short of the lawn dart scenario.
Of course you'll need to make TWO of them to keep the peace. In fact make 3 and have little impromtu contests. Elestic catapult launching saves the arm and any shock stress to the back. Winning can be based on silly things like how close to a given spot the models land. How many loops they can make them do off the launch... stuff like that.
1/8 or 3/16 for the fuselage and 1/16 for the surfaces. Choose lighter wood to keep the weight in check.
Good luck and fast healing. Take care of that back, you only have one you know....
