Default RE: 4-stroke engine for pattern

For a 70-inch wingspan model, a 4-stroke 1.80 is very heavy![X(]

Is the 1.40RX new? Are you using a pump? Where is the fuel tank located? Plumbing completely sound? Right plug? Carb high and low settings correct? Right fuel?

Maybe figure out why the 1.40 2C isn't working...
