I watched when I was little.
Two Asians - young and older, older completely bold. They were fighting. I remember a scene on wire (an acrobat?) and a part with buried in the sand little remote control cars that were used to fight with true cars (police cars?). I have no idea what was the title, but would love to watch again :)
:hot:
This is Aces Go Places (1982), also known as Mad Mission, with Sam Hui (the young guy) and Karl Maka (the bald guy).

The scene with the model cars is here (and the whole movie):

One of my favourite movies as a kid! Absolutely hilarious with lots of funny gimmicks. In the beginning someone is trying to kill him with a series of remote controlled helicopters that join together to become a Japanese-style robot!
