why is my drone not accepting know same size batteries used in my airplanes?

I have this world tech drone and it came with a good battery 2S 1200 Mah no C rating on it.. .so I tried my airplanes battery in it that are very good in the airplane however fail in the drone and slows down .

of it maybe the drones uses a lot more current so my 20C battery's wont hold up?

maybe you need to use the battery trap to hold it. like these: https://www.genstattu.com/ta-fastener-yellow-150mm.html

Your drone has 3 more motors than your plane and it is possible your 20C batteries are not up to the claimed specs. Only way you can tell is by using a watt meter but I can guess your batteries just are not good enough.
What you describe is a battery that just can't hack it..
