How to use new engine mounts?

[cocoscacao]

In KSP 1, you could attach several engines to engine plates.  I cannot find where to increase/decrease mount points. Also, in KSP 1, they also behaved as decouplers, while here, as far as I can see, I need a decoupler underneath it. Am I missing something?

The KSP2 engines can be surface mounted to the plate and do not have to be attached to a node.

Hmmm, nice. Though I still need a decoupler underneath it. Oh well. It is an improvement overall

I can not attach multiple Rapiers to the engine plate, but other type of engines do attach. Am i doing something wrong, or is this a bug?

Is it possibly because the Rapier is an air breathing engine? Granted, it’s got a rocket mode, but fundamentally its an air breather right? Have you tried other jet engines? If other jet engines behave the way the Raipier does that might indicate that this is a feature, not a bug. OTOH, if other jets can surface mount for multiple engines then this is more likely a bug and should be reported
