I am a beginner in rc planes. I am building a plane (airbus a320 model) which will weigh approximately 2-3 kg. What is the thrust i will require to fly it properly ??

Thanks.

At least 1.5 kg if 2kg plane...
But being a beginner you must not build it dont try you will mess up badly try theft alpha....
I say again beginners should not make 2 kg plane...
And the motor with that thrust will cost a lot...
Build flite test's ft alpha...
If you don't know about flite test search on YouTube and see it's beginners series if you haven't....

You were born an original don't die a copy.

If the plane weighs 2kg and thrust is 1.5 kg then how can the plane fly ? For this get a low kv motor swinging a big prop.

Even if thrust is half the weight a plane can fly..
When both are equal then vertical takeoff..

I can comfortably take-off, fly and land a model weighing 2 kg with a power unit producing 1.2 Kg thrust

Just go back to basics - lift is not the same as thrust. If you want to climb vertically, only then thrust > weight

That said, do not underpower! Always safer to have thrust:weight around 1 for trainers, 1:1.2~1.5 for sports models, and 1> 2 for 3D models
