Same thing happened on my rotor. After trying to search for tutorials on what size SMD leds to replace on the internet, I found basically none.
Perfect reason to try and modify mine! Instead of using an SMD led which requires a bit more soldering skills, I chose the 3mm LED which are bigger and easier for any beginner to solder. Hopefully this will help many of you out there who either has a burnt out LED on the rotor OR would like to spice things up with their setup and match their color kit.
Here's an example of my LED work from a few years ago... I told you it's been a while!!!
We were on a speedball field and I took dorito side and thought everyone was cleared.
As I am walking back to the staging area, I see a head pop out from snake. I hook around to his 6 0'clock.
Shot him a couple of times but he didn't seem to hear me or feel the shots.
I walk a bit closer and take 1 shot to his butt.
