You just can't keep a good bandsaw down......

You do like those canards don't you? :-)
My feet are killing me!
I just framed up a wing. Still got the sheer-webbing to put on, and the trailing edge to sort out, and the hinge-blocks to in-fill and the wing
dowel to reinforce, and the mounting bolt blocks to add and the joiner rod
to align, and the leading edge to profile, and the servo bay to design
and build, and the ailerons themselves to make but it's almost done. ;-)
Then the *other* wing will need doing.
Yes, I rather like the canard design, but this is my first POWERED canaed
and there can be some difficulties associated with the designs. For
instance, the CoG has to be done with a FULL tank instead of an empty one,
and it is possible that I'll have to ignore the plan and invert the engine
so as to get the carburetor jet in line with the tank outlet, and I've
decided to use six servos giving me full programmability on the
surfaces...
And canards are supposed to be un-stallable, which makes a range of
aerobatic maneuvers (that depend upon stalling the wing) impossible, like spins, etc. And with pusher designs, over-rotation on takeoff usually
leads to a stopped engine and/or a broken prop... But it will be an interesting experience and an unusual configuration at out club.
I'm looking at the winglets. I intend to make mine bolt-on so they can be easily replaced in the event of a shunt. I'm wondering about sexier
shapes. (This plan was drawn in 1979!) And should I put tiny, matching, replaceable winglets on the forward plane as well? And should I make allowance for moving the main-gear aft? And the fin (*under* the model,
and not visible in the photo) and rudder look small, and will probably
foul the head of an inverted design, so maybe I should move it to the top?
Why, oh why, did I start this! :-/
