Wing spar, tips and joiner set - high and moderate lift versions included
by northshore, published
Designed as a stable high lift trainer wing for the Hobby Zone mini cub.
Includes, left and right fuselage joiners and wing tips as well as the spar sections.
There is a centre joiner piece included for a straight wing, which will need to be resized as required.. nominal recommendations are 17mm wide, unless you want to extend to use it as a single piece for the width of the fuselage (suitable for those with a brushless conversion only).
Can be assembled with or without the 5 degree joiners, or use the 15 degree joiner for a poly wing (with angled wing tip sections).
The stl file with the two wing tips contains a shortened version of these parts.. seems to work fine, saves - 5 - 6 grams.
Notes post first flight.. is a very high lift wing, requires additional weights to ensure a nose down balance point.
The Version 8 files are a less agressive lift profile, is matched to the Version 5 centre spar for the centre join, wing tips and angled joiners included.
New files added...
All printed with 2 shells, 30% infil and .25mm layers.
Feed rate of 45 and travel rate of 55.
Assemble with 3mm carbon tube or rod and 6mm square hollow carbon rod.
Sheet with 1mm blasa, sand the edges and cover with film.
All up weight is a bit more than the standard wing (65 grams, increased to around 94 grams), but is infinitely stronger and extendable for use with powered up versions of this plane.
