Do Conards provide lift in level flight?
So as the question states, do adding conards to a jet add lift thus changing the CG?
This is a NASA F15 they used for STOL testing, apparently they took F18 elevators and made the big Conards on the F15
I'm currently Restoring a Byron F15, and this is definitely odd and was thinking of adding this feature to my build, but worry about CG changes

Agree on the lift, there will be some, but IMHO, how much is going to depend on it's angle of attack, especially as compared to the rest of the plane. Figuring the CG might be tricky. At take off and landing speeds the canard will no doubt have a lot of lift. As speed picks up, maybe not so much?
Might be a neat project, but I think I'd be tempted to add a canard to an inexpensive foam EDF to do some initial testing. That should be able to guide you on a bigger project.

Using a foam EDF for testing would be a great idea, maybe along with some simple chuck gliders. A lot depends on whether you would still use the model's existing elevator for pitch or these new canard surfaces (probably the worse option).
The balance of the plane should not vary depending on speed and load, at all. If there is an effect at one speed, it will be there in others too.
