I do 'full flyin' stab connections, but to infividually control a side, you would be generating all kinds of adverse conditions, due to dynamic loadings: Consider a left hand turn: you are now employing aileron type control inputs on the front end, wayyy in front of theCG,twisting forces will go into the fuselage framing,and all the weight of the 'following' part of the craft would be 'following' that input, which even though 'fast' the moments on the main wing and rudders etc, will dampen the inputs. the only 'positive thing that MAY help, is very small inputs as an assist on a (sailplane) in a very windy situation. ( I lost my avatar bird in a strong cross wind, as it was blowing sideways, mostly uncontrollable) till terra firma got the last word. I sure won't ridicule ya for trying it, though, just epect crashing, so don't be too 'attached' to the bird!

I reckon I'll just have to wait on the folks at Rutan.

I DO however find it ODD there are no vendors out there producing this good looking, easy to fly (presumably) air frame!

All the best!

One more ducky question, on a jet with elevator and canard, does it make any difference if the canard is mounted higher or lower than the main wing?

Thanks again.

Generally, I mount the canard below, as that will keep as much 'clean air' on the main wing as possible. Hoever, Charles and the gang here have proved with enough propelations, it doesn't seem to matter!

This is not a yes/no answer.
The issue is the wake interference from the canard - there is always some range of AOA/airspeed where canard wake is acting disadvantageously (usually most of the flight envelope).
There may be a narrow part of the flight envelope where the interaction is such that it actually enhances lift of the rear wing. So that the net effect is better than a conventional design (lifting canard and beneficial wake add together in that part of the flight envelope), assuming all other major factors are equal (weight, wing loading, etc). In commercial canard planes (Rutan's Vari-eze, Long-EZ, etc.) that is the cruise configuration - the canard is optimized (size, position, incidence, camber, etc.) for cruise performance - with the assumption that the vast majority of the flight will be in cruise configuration/airspeed/AOA - which is mostly not true for model aircraft .
Higher stall speed is typically the most disadvantageous feature for the vast majority of canard designs. I try to compensate for this by making my canard planes with ridiculously low wing loading.

I remember my Grandfather telling me about the weather back in the "old country"

Doesn't sound like a long lived plane, does it?

I like it too Nick. How about making the main wing a delta and extending the fuselage rearward with a fin/ rudder on top, a pusher motor and place the CG in the center of the fuselage for good elevator and rudder leverage?

Good to hear from you Charles and I like the idea. I'm sure it would look better with a single fin and the motor mounted on it. That Short EZ used to have the prop striking the water on take-off until she got up on the step. So a higher mounted motor would allow for a larger prop.

That plane gave me a huge amount of confidence in flying with a rearward C/G. She used to do very impressive flat spins.

Lancer31, I have 2 of Tom's canards, one is identical to the one you posted. I am trying to figure out how to set them up. they did not have Rx or batteries. servos and linkages are there.

The canard has multiple linkages to the surfaces and to a bell crank that controls the front gear, confusing on how to set that up, the surfaces act funny when I steer the gear manually.

Look at my thread on Tom's models again. I tried to explain things there.

Thanks Captain, I may not be on line for a few days.

jdpeltz, Thanks for the news. I trust that there is still lots of canard help here.
