quick question. So I just bought a KO Propo servo which I wanted and I noticed that the servo has a extra tab on the edge of the plug (or whatever proper name it has) that goes onto the receiver. Same for the default servo that came with the HPI Vorza. The HPI RF-11 had that extra tab space that accepts both the HPI servo (duh) and my brand new KO Propo.

However my Sanwa RX-461 does NOT have the extra tab to accept both servos. The extra tab I'm talking about is to allow you to know which way you are suppose to plug in your esc and servos but the 461 doesn't. I read that I can "shave" off the tab and I should KNOW exactly which way to connect the servo. Which I obvious don't and I could possibly fry the servo. So is there anyone who can get me going at this?
