Hobbyking EZ Master Firewall / Motor Mount

thingiverse

I wonder if there are any of these models still in the air, given the well known tendency for the wings to come off mid flight. Perhaps that's why hobbyking discontinued the model. If the wings ripped off your model and fluttered slowly to the ground while the fuselage was doing an impression of a lawn dart you may well have a broken firewall. Usually I would just cut one out of plywood, but this firewall was designed with varying thickness in order to give the correct thrust angle, so I thought is was easier to make a 3d printer model. I didn't bother adding the locating tabs on the rear of the firewall. I also have a model for the nose gear brackets here: https://www.thingiverse.com/thing:4751288
