TOPIC:

I found this engine attached to a gear box of a vintage Hornet.
The size is equal to the Mabuchi / Johnson 540, anyone can tell me
If the performance of this engine are greater than or equal to engines
540?
Thank you.

I looked it up, supposedly it's "just" a 27 turn single so nominally the same as the "silvercan" motor Tamiya usually supply ... however as it does have a rotation direction I would guess it's been given a bit of advance on the timing to give it a tiny bit more poke ... I think you'll have to try it & see, but I suspect the difference will be barely noticeable

I read this on TC :

The Kyosho Lemans Stock 05 was originally made for the twin motor monster trucks, so they were made as a forward rotation and reverse rotation pair. Silver label on the forward rotation, gold label on the reverse rotation one.

I think he did a bit of a switcheroo though. If I'm not mistaken, reverse rotation normally means forward motion.

Thank you all, I was just curious

Yes Edou, rotate the endbell backwards gives faster forwards. You normally lose torque doing it though.
The missus has a green Le-mans in her Madbull (Can't remember which one, but it's adjustable/rebuildable, & has ballraces). From memory, the rotor is a 27 turn one, but it's pretty mental
