The Porter has received the same 8mm carbon spar update as the Skymaster. Whilst the model doesn't 'need' a spar I understand from those in hot climates, or just those looking for a more rugged plane that is an upgraded that people want. As such I have uploaded a wing with spar as a free download to the Porter page.
Thanks as well to one of our builders for some great photos of their Porter which includes a really nice addition to the landing gear. These files were downloaded from thingiverse and, when scaled to 90%, fit the Porter really nicely. It has always been my plan to design these updates into the Porter but time seems to race by. I hope these additions will help all the Porter lovers out there.
