RE: Canard configuration airboat CG ?
@pinky_d_brain I apologize I have missread your message regarding the CG. It looked strange to me also anyway but a picture just striked me later where a canard boat is on its stand but with the back part of it. If the CG would be where I have told in the earlier message it would fall in it's nose.
Regarding the thrust,would be best to have the prop close or far back from the CG? To me it looked it not makes to much diference as @Altered1 said I will need to be able to adjust the thrust angle.
