in the last month i bought both 1/8 muggy and lst2. I'm curious now i have them broken in, what heat range do you guys run? I'm using os a3s. seem to do fine but I'm wondering if a a5 i could lean them a bit more??
 
apparently Losi suggests an MC-59 which is an os a3 but a tad longer. i'll how that'll work. my muggy has an a3 that has lasted almost 2 gallons, but lst2 is broken in and still killin a3s.
 
A buddy of mine runs OS #8 which is their medium/hot plug (because it's what I had on hand) in his LST2. He's been getting a gallon or so at a time before frying a plug. He's a little green in the tuning department yet though.
 
os#8's are the best but they have a problem if your engine is not tuned decent they will foul real fast, you should either go with a mc coy 59 or an os 8

and if you were asking about a temp range for running temps dont let it get over 230
 
also forgot to mention that these motors are best run on medium heat range plugs!!!

also try an odonells plug they are pretty damn good!
