If I remember from the past, Axe is Axe Rossi and Nova is Nova Rossi. Rossi. Nova Rossi kept the name. In the early years, there was a Black Magic, Golde They were two brothers who use to work for the same company. Ugo, or the other brother Mario broke off and started Axe or I think at the time was originally called Just n Arrow which had an Alien looking head. There was later an LSK and then some sports type engines. The Black Magic during it's time to me was like the GRX Engine for Speed racer. At the time the engine was just stupid. lots of power, 4 wheel burnout on asphault. Break In was quit long, and if done right, then engine could take some serious abuse without failure. Although i think the engine did have a faulty connecting rod early on which was fixed. I still have a black magic and I don't think I have ever leaned the engine to its max power. There has never been a need to. The engine ran really strong even when a little on the rich side. I have wanted a Golden Arrow for some time. I have a Black Magic and an LSK engine and also a .12 engine in my onroad car. The .12 I don't think is that good although I have not leaned it out fully as well. I would like to own a REDs engine, but, seeing how our track has closed, I can't justify the purchase.
