Making prop motor Guards for your micro quad

I'm sick of searching for this post so I decided to add it to blogify it:

The last is the Mini Pets motor mount that also has a plastic cylinder rising out of the mount to limit the prop from impacting the motor.

Here you can see the difference between the protected motor on the left and the unprotected one on the right on the Hubsan. This picture also shows my effort to reduce vibration by putting hot glue on each side of the motor where it contacts the Hubsan motor mount:



UPDATE: Simply taking some old V202 props and cutting the prop guards off of them works better. They won't fly off the shaft like Capr Sun props guards will if the prop itself comes off.

You want to cut them off straight, but they'll still work if you're square\perpendicularly-challenged like myself:



With Mini Pet props on top:





Make your own prop\motor guards from a Capri Sun straw:







If you want to make a bunch of them with some consistency, just rig up your caliper:

In addition, you want to remove the bottom motor cup and make sure your motor wires are oriented so that they line up with the boom:



The reason for this is that the wire channel will cut into the wires on a crash if they're not properly oriented:

Thank you for the very nice How To, but unfortunately for us 'Down Under' we don't have Capris Sun straws
Would you mind whipping out those calipers again and measuring up the dimensions of the cylinder needed ( OD x Wall thickness x Height ) so we can find ourselves an equivalent plastic tube/straw to use?

Also, the tip on checking the motor wires should be heeded by anyone you has a v939. My original v939 had a motor die after weeks of heavy use/abuse. On removing the motor cap I found a wire severed due to this exact issue. I now check all my micro-quads before first use and realign the motors if necessary - it only takes a few minutes.

Hi Maca,

You can use ink pen tubes or WD-40 straws as well but any tube that will fit over the motor shaft will work. If it fits snugly on the shaft, it's even better as loose tubes can sometimes come off if the prop comes off in a crash.
