"I want to make a Dule engine bomber stle plane what is the best way to do this and how much a load can they carry? Coast has to be high to right?"

If I translate this correctly, you mean, "I want to make a dual engine bomber-style plane. What is the best way to do this and how much of a load can they carry? Cost has to be high, too. Right?"

If that's correct, then the answers to your questions are:

1. The best way is to buy a kit of the model you want to build, then build it.
2. You can increase the load until it can no longer fly. Then you have a dual engine bomber-style car.
3. Yes, cost will be high.
