I'm having issues with the added 0.6m Turboshaft engine. Upon cloning the part with attached propellors (either via alt+click or symmetry), the propellors shrink to about half their original size on the cloned engine. When loading a craft the same happens for all engines. Now I'm using a heavily modded instance. so this could be due to a conflict, but I wanted to get this out there anyways. Cheers!
