Recommended Fuel and plugs for Losi 2.0B RTR
 

I'm relatively new to nitro and was browsing through the Losi manual. Apparently the recommended plug for my 350 engine is a DYN2495 and 20% Nitrotane. Are there any better options there in regards to lower temps and longer runtimes? I was thinking of running a Mc coy 59 and some Byrons 20%. Also if I decide to go with a Mc coy 59, should I remove the stock plug and break it in with the Mc coy 59? Any adive would be appreciated.

Byron and Nitrotrane are both great. Really boils down to what fuel you can get the most consistent access to. I've ran both, and like byron a little better, but that was 30% fuel while Losi was 20%. I like O'Donnell plugs but thats just my opinion.

There is no need to change the plug for break in. Just change it before you start to tune the engine, after break in.
