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

thingiverse

Here's one of the 2" prop frames I've made, designed for 20mm stacks and 9mm M2 bolt pattern motors, with 50mm props. The stack is run diagonally for the smallest footprint possible, and clearance to the stack is pretty tight (but could be tighter, but would just mean for more negated thrust over the FC). I've included my minimalistic 25 degree camera mount but of course you can use any 20mm footprint mount you like. Pictured is my build running Lizard 95 prop guards with pushrod tubing for reinforcement. I found that without the tubing to connect the guards, I had fairly noticeable vibrations, but after adding the tubing it flies awesome with no resonance whatsoever. My implementation involves having M2 standoffs that thread into the four FC bolts, and if you do the same (I did it so my battery mounts flush) you'll want to tap the holes with a metal M2 screw before trying to screw the nylon standoffs in. For motor screws you'll want M2x7 if running Lizard prop guards (3mm thick) and M2x4 if running commando. Enjoy!
