He can upgrade his cars engine, tires, etc. and when you get on the the track, the Game will throw in that you have a heavy rear end, stuff like that.
Is there a game where I can compete against unlike airplanes?
If I can make this happen, I expect to be the new internet Pinata.

I haven’t played it but the same people that make “World of Tanks” make a “free to play” online multiplayer “World of Warplanes”. Warplanes | World of Warplanes
A couple of friends got addicted to these, I have no idea if the planes fly realistically but there is a lot of variety of types to choose from, although it seems to be all WWII, not Vietnam era, if that’s what you were looking for.
No, just in general.
You might try WarThunder
I can’t recall any flight/racing games besides one for the old Playstation (1) called Bravo Air Race. If you want to compete, online (or off) with other airplanes, especially WW1-WW2 era planes in combat and time trials, I suggest and highly recommend IL-2 Sturmovik and most importantly, BIRDS OF STEEL, you can customize your planes to some small degree as well (decals, paint, weapon loadout) and there are DOZENS to choose from, even bombers. For new Jets, a lesser known but nonetheless OK game is Tom Clancy’s HAWX.
OP is incoherent. Does not mention which racing sim it is, then says that he instead wants a flight sim. 
I believe the OP is saying his son is playing a very complicated and realistic car racing game and he is looking for a similarly complicated and realistic plane flying game. The video is supposed to indicate the type of plane flying he’s interested in (smaller war planes, not a commercial flight sim or a crop dusting simulator). Whether he’s looking for a game where your plane engages in combat or a racing sim with planes I can’t tell…
