Okay, since I am an aerospace engineer to be, I know what they are. On helicopters, they eliminate torque effects without the need of a tail rotor. But when used on conventional aircraft, do they serve the same torque effect reduction?

I'd image they do.
The helicopter design probably adopted the idea from conventional aircraft.

Thank you very much for the info. I really wasn't sure about it. I had wondered for a while if it was the same, but until now, I ignored it and thought it makes the plane look cool.

Piper did it once to a PA-22 Tri-Pacer. They installed two engines on the front, and spun two props opposite directions. I have a picture here somewhere....

Don't forget the An-22, An-70 and the TU-95 in all variants...
contra rotating props is a good way to get all the power out of the engine whitout having to use a huge prop
