Will these work on Novarossi .21 engines?
You'd need to measure the bolt spacing to be certain, but this most likely does NOT fit your Novarossi.

Any idea on fitment for the HPI G Series Nitro Star Engines 12mm hex engines like in a RS4 3
You will need to measure the backplate holes on the motor to know for sure. The diagonal measurement for the mounting holes on the rotostart back plate measure 39mm on center.
