Some will claim Thunder Bolt RC long is the standard
others the KB-1L
still others the Fox Miracle plug or some form of good OS #8 or Enya#3 plugs

I have two Ringmasters with Fox 35s... one a old skool and one Lew Woolared re-worked 50th with muffler

Until the ( as supplied unknown) factory plug stops working... they are what I am using...until I dip into my very small supply of the Stunt Hanger recommended plugs...KB-1L and TB Rc Longs

So far with my prop (9x4 apc) and fuel mix( 15%N 25% oil ((20 C/5 Synth)) they start reliably, restart when warm, and with power to plug off, I do notice any not sag in RPM

I am NOT a serious competition pilot so all maneuvers are sedate and don't ask for max performance from the engine

if Randy Smith responds follow his advice

I've used the Thunderbolt and the Sig RC Long with equally good results.
