RE: noise level
It kinda sounds like a stroppy cat screaming into a mic.....sort of anyway!
On idle they arnt that loud, and with the shell on they are alot quieter. You could get some kind of 1/10 truck with a .15 engine, they are really quiet in my opinion, when your used to a savage anyway.
Also lawnmowers are much louder! We have 5 lawnmowers and they are all much louder than say a savage, swift 2 etc..
