Motor firewall reinforcement for Skywalker 1900/1800/1600 (2016)

thingiverse

This is a reinforcement for my adjustable motor mount design, specifically made for anyone who owns the Smallparts CNC motor mount for Skywalkers to use with larger props. You can find it here: http://smallpartscnc.com/index.php?route=product/product&product_id=145 The challenge with this design is that due to its higher-than-expected position when the motor pushes, it produces a rotational force similar to a lever in the original wooden motor mount by pulling on the screws instead of pushing them as intended. With this reinforcement part, not only is the entire motor mount reinforced, but the resulting force vectors applied by the motor remain the same without any rotation. This plastic part will only work effectively if the adjustable portion is placed exactly as shown in the pictures, which was the position I found to be necessary for using a 12-inch propeller. Feel free to modify it if you need to use larger props. The screws used are M3. The screws shown in the picture serve only for illustration purposes; please use an M3 screw of suitable length for your specific application. UPDATE: There are two additional versions available, each with a hole for a shaft in case your motor requires one and different anchors to choose from. Simply pick the version that best suits your needs. If you need a specific feature changed or added, just leave a comment explaining what you need, and I'll most likely add it. UPDATE 2: After careful consideration, I've found the six-rod mount option to be the most effective. Additionally, I've included two objects designed for use as guides when marking the rods on foam: one for initial marking and another for perforating all the way to the exact depth of the real motor mount.
