I wanna control sitl system

Hello, I have seen arducopter opensource for one week. But, I can’t control motors. In virtual arducopter, what should I touch parameter? or I need to explain why the parameter or function have a relation.

if I write some code, one motor is rotate, one motor is stop or something.
I wanna control motors!

Thank you for reading my question. Please help me

oh sorry This is Sitl!

OK, so you have SITL running - good start.

Are you able to run the simulation normally?

Are you trying to create a new frame type? What are you trying to
accomplish?

Yes. I am running SITL ArDuCopter (…/Tools/autotest/sim_vehicle.py --console --map)

I wanna control simulation motor power like actual experiment.
like this, if my source code value was changed to related motor power, like 50%, is it possible to fly?
or like 40% power, is it possible to fly?

I found a parameter. name is SIM_ENGINE_MUL. It controls motor’s efficiency. So it is my hope parameter!
But this parameter have errors. If I change the parameter (SIM_ENGINE_MUL) to 0.6, it works. But, 0.4 (40%) 0.3 (30%) 0.8 (80%) 0.9 (90%) … umm … 0.7,0.8,0.9 takeoff time are same and 0.1,0.2,0.3,0.4, 0.5, 0.6 takeoff time are same to zero altitude. it didn’t have differences. It’s same.
So Maybe It is not works.
I wanna experiment. I wanna extract the usable data.

Or other control(like yaw value ,roll value) wanna control to this SITL
