With the use of an IBEC you have the availability to shout down the engine at a flick of a switch so no real need for a mechanical safety. IMO most guys go cheap on the throttle servo so being under load all of the time might shorten the servo life. I emphasize the word might here as I have no evidence of this. When it comes to gassers there is a very wide spectrum of opinions on how to do things. If you want options, ask your question and then select the option that makes most sense to you.
