Need more info. I fly the C130 and have had engine out 2 times in 30 flights. But they were bad fuel and fuel starvation.

The bad fuel caused an engine to drop out at random until I switched to a different gallon of fuel. (Both gal's were the same brand and bought at the same time). I called the mfg and they were more than helpful. Email me privately and I will tell you who's fuel.

The other flame out was due to the fuel tank cap being loose,, (some dummy who built it forgot to tighten the screw ) After landing and repair the tank it has not flamed out. I fly the saito .30 and us OS F plug with a 10x6 prop. Fuel currently used is Omega Cool power 15 % all synthetic. I have had no flame outs since I corrected my fuel issues.

So to be helpful we need"
