Neither an arming plug or Failsafe would have helped that situation. We can't legislate for every failure mode. Conscientious participants will be the best solution.

Saw it last year where the contest was frustrated and walk of the flight 
line before plane was retrieved. 
He inadvertently hit the throttle and plane went airborne...for a few 
seconds and crashed in on the other side of runway fortunately.


 
Point is it doesn’t matter how well the system is 
armed/disarmed stuff can happen.  It takes a level head and common sense to 
prevail.
 
Dave, point well state on the startup up of 
IC’s.  Has happened to me when throttle was nearly wide open.  
Thankfully I still have all my digits.
 
Smooth FLying...

How many runaways have happened with electrics at pattern contests?  
Since maybe 2008 when substantial numbers of electrics were being used?  
Personally,  I have never seen one.
 
How many IC engines have I seen inadvertently started at half or full 
throttle since 2008?  I have personally seen several.
 
Have there been instances of of arming plugs and wiring fail?  
Yes.
 
A lot of things could go wrong resulting in a potential safety hazard with 
IC or electric patterns planes.  Having a safe procedure and sticking to it 
100% is the issue.....accidents happens when procedures are not followed.  
Arming plugs themselves do not make electrics safe....they do introduce another 
failure point.

At nearly every contest I've attended since I started flying electric in 
pattern (the 2004 Nats in Masters) I've seen at least one occurrence where 
someone retrieved a plane without removing an arming plug first.  Usually 
the pilot reminds the person to do it while they're carrying the plane back or 
as they're setting it down somewhere.  It happens with my planes too and I 
make sure they switch the receiver off and then I remove my canopy and 
disconnect the battery directly.  But before they even get that far I've 
taken the other steps to make sure there's virtually no chance the motor is 
going to run.
 
My point is this.  A layered approach is the only way I've found to 
effectively mitigate this particular risk to the levels of safety that you 
claim.  Relying on someone to remove an arming plug is not a complete 
panacea and may lend a false sense of security that the motor system has been 
de-energized, when in fact it may not have been.  There's many ways to 
manage the risk to the desired level, the use of an arming plug is one, and may 
not necessarily be the best.

  I use the Ultra Deans stlye Arming Plug from F3A Unlimited, 
  and It works very well. I would gather it provides you with a 99 % dagree of 
  confidence that your caller , plane carrier , yourself, or anyone else will 
  not be harmed. Yes... I do agree that there is a miniscuel chance that a pilot 
  / caller could forget to unplug the safety, however I feel most pilots that 
  have been doing it a while is like tying your shoes, or etc.... On all of my 
  electrics except for indoor ships, I have some sort of disconnect. I for one 
  would like to see it an inforced rule at all sanctioned meets not just pattern 
  meets, that any plane over a certain size or weight must have one in order to 
  fly. Just my three pennies
