Ha, so speed cost money to do it right.!!

I want a engine that will last a season, with the ****e flown out of it, am i dreaming? Hence this is why I've upped to edl 18%oil on the 50v1. To be honest I think this has helped prelong its life for the season. The weston pro synth fuel is an unqualified amount of oil. They wont tell me, so i Changed fuels.

But the 36v1 on the same 18%oil 16% nitro behaves differently, a plug a flight, difficult to tune, i mean the needle is only a 1/4 turn out. Maybe she is more compressed. I know when new she is very tight to turn over but sweet when running.


So if I want to maintain the new fuel for all my engines, do you think the shim is better way to go than resort back to lower nitro?

You see Im confused to wether a highly compressed engine on high nitro is as damaging to a plug than a geniune lean run at end of tank and knoweledge to know the difference.!!

Plugs are expensive,if you pop em every go.

Then you get on thickness of the platinum thats reacts with the nitro. More nitro, bigger element(colder plug) to react with less methonol and the choice of transition from very cold to cold plug
