77- Size Dreamcatcher frame for 50mm props (Lizard 95, Aurora 90, etc)

thingiverse

Here's one of the 2" prop frames I've created, designed specifically for 20mm stacks and 9mm M2 bolt pattern motors with 50mm props. The stack runs diagonally to minimize footprint space, and clearance around the stack is relatively tight - but could be even tighter without affecting thrust over the FC. My design includes a minimalist 25-degree camera mount that fits snugly on the 20mm footprint. You can use any other 20mm footprint mount you prefer, though. In this build, I'm running Lizard 95 prop guards with pushrod tubing for added reinforcement. Without the tubing, vibrations were noticeable - but after adding it, the flight is smooth and vibration-free. My setup involves using M2 standoffs that screw into the four FC bolts. To do this yourself (I did so to flush-mount my battery), tap the holes first with a metal M2 screw before trying to screw in nylon standoffs. For motor screws, use M2x7 if you're running Lizard prop guards (3mm thick) and M2x4 for Commando - enjoy!
