TY!!! I was totally perplexed by how to install the guards. Recognized some snap-on potential…but hadn’t looked for the extra screws inside the “spare” prop baggy. (Didn’t read ALL instructions - now I see it is at the back with propeller replacement instruction). Surgeon hands for sure. Use a flat white background (you will likely drop a screw). You saved me some prop replacements for sure. 😂👍🏽
