Hey there, I bought a ACME 1/10 Nitro Buggy, and its gererally the same as those Smartek buggies... But it has 2 speed.

Basically, the clutch bell has 2 pinions on it, both mesh with 2 spur gears... at the same time...

So how do I know if it's changing gear?

It seems like it has a sudden burst of speed when it gets close to max RPM... but no drop in RPM...

Any help is appeciated!

Cheers!
