Default RE: mounting bigger engine on F22 raptor

Hi,
I have just changed the Evolution .46 Engine that came with the F-22 to the new Evolution 52FX. The new .52 FX is the same size and configuration as the .46 with more displacement and fits perfect wihout any alterations. It weighs 1 ounce more and has a lot more power.
