I've always thought that most of the ESCs we use will cut the throttle in the event that the throttle signal is lost (like a failsafe would). I am about 90% sure that an ESC like the Mamba Max would have this feature, and in some cases I have noticed that it does (from it activating the "failsafe").

My case is rather peculiar. I've been having pretty serious glitching issues for close to a year now, and it had all occurred using the same MX-3 transmitter (75mhz FM). Earlier this week I got another MX-3 transmitter (used) from Ebay, along with a new set of "genuine" Airtronics crystals. I have two receivers that I'm using right now, and both are Novak XXL receivers. The one that was in the Rustler last night isn't in the greatest condition, so it's very possible that it's not-so-good condition could be causing the glitching. But my other XXL receiver is in much better condition, although I have yet to try it with both the new transmitter and the "genuine" set of crystals.
I can't just get a new radio system, since I'm on a VERY tight budget for what I do in RC (brushless + Lipo everything).
Some time I will have to make a thread of my own for discussing this problem, since I don't want to take up this thread.

But since you asked, I looked at the neighbor's car this morning, and it appeared that there wasn't any damage. Granted, I didn't go up right next to it and look, but there was certainly no noticeable damage, so I guess I only hit the bottom of the muffler.
Funny thing, I asked my other neighbor friend if he heard a loud thud that night at about 9:00pm, and he said he did! Although I will admit it was pretty loud...
