I opted for a complete T-motor set (motor,ESC,prop): Fighter VTOL 4+1 fixed wing - #491 by Rolf.
Best you scan through the above thread. There are many helpful posts and links, especially from GregCovey, god rest his soul.
Why do you want to rebuild a parachute bay ? I think it exists because the Fighter was also advertised as a 2-mot with the option to land it regularly by parachute.
As a safety feature, that would be different, of course.
