I too would like smaller jets as i fly and live near bigplumbs, I did ask for smaller jets on the flyeagle web site where you can choose to ask them what you would like to see next but if they will take any notice we will see.
i belive yt will be bringing out some smaller jets in 2009 just hope they are not heavy small jets.
i am sure someone one day will capture this untapped corner of the market soon.
