How to turn off the overweight penalty?

[Mole]

Hmm,but how can i take my B737-800 full with pssengers and cargo for exsampel from Frankfurt to Oslo without to get penalty?
In fsp i get a message"you have disabled the payload loader" It is possible to do that in fspx? I know it is not like that in the real world, but
i want to earn money and get so many passengers on the plain as possible
