blade msr

Someone on the RC Groups forum wanted to know the gear ratio of the Blade mSR so they can possibly use them on another RC vehicle. I took a picture and figured I’d share here.

Blade mSR Pinion and Main Gear

Just a public service announcement regarding E-Flite’s Blade mSR 5-in-1 RX board. I learn the hard way that E-Flite has at least two revision of the 5-in-1. And between revisions, they also reversed the polarity of the battery plug. I didn’t realized this when I had to replace a fray battery plug on one of them. I took a quick glance at my old 5-in-1 board to ensure I got them soldered on the correct way.

Unfortunately for me, the two boards were different revisions and the battery plugs were suppose to be soldered on the opposite way from one another. See the photo below:

So now I have two bad 5-in-1. Major bummer, but lesson learned.
