On the park jet plans it shows a slight downward angle on the nose along with the wing. Seems it would cause it to nose dive unless a lot of up elevator is applied. Take a look at the 140 mark and
I believe its meant to be like that, as the planes wing has a slight up angle of attack when flying it makes the canard on the front look like its pointing down but in the air it will be level.
Not 100% sure myself but that would make sense
I think your right. I have 6 different park jet full size plans I had printed at Office depot. I checked those plans and each one has the same nose angle.
