I need to sell all the ducted spoilers first before I go and make any more spoilers again ducted or non-ducted.
The demand is just not high enough for me to keep making these things as it is very expensive to produce them.

Also I am very busy with school still and I don't have as much time as I would want for all my projects.
Will I make more in the future? Of course I will but, unfortunately not any time soon
