After yesterday’s successful (albeit very short) flight, thought I better install the Prop Support upgrade as suggested by the manufacturer.
Couldn’t find any of the fibreglass support upgrades on line anywhere so nothing else to do but design & 3D print them.
This is the factory version
and this is my 3D design which I think is pretty close (well it fits OK anyway).
Installed
Also replaced the blade fixing screws with a slightly longer version for better fixing.
