Quadcopter F450 Arm Shortened by billkaroly

Last crawled date: 3 years ago

UPDATE 2/23/2017 The arms are redesigned for a carbon fiber rod (5mm OD) reinforcement. Buy some 5mm OD rod and cut it to 118 mm lengths.
This is a remix BUT I can't find the original STL file. I want to rebuild my Cheerson CX-20 quadcopter in a F450 style frame but I wanted the arms to be shorter. Using Tinkercad I removed the center of the arm and joined it back together. I also removed what I fell is excess plastic down the center. The original file had a hump running almost end to end. I also added a ring of plastic around the motor mount.
When I find the original STL file on Thingiverse I will give credit where it is due.
Print in PLA, 4 shells and 40% Infill.
If you purchase a F450 kit on Ebay use these arms but add M3 inserts with a M3 screw and insert using a soldering iron to melt the plastic and press in the insert.
