IIRC Revell did a 1/72 F-111B way back in the stone age. The TFX (F-111) project and the F-4 Fanthom were Robert MacNamerra's (sp) "one size fits all Military services" idea.
The Navy found the F-111 to be to big and to heavy for carrier operations, as well as to complex. The F-111 has had a great service record with the USAF and other air forces.
Like any cutting edge project, e.g. swing wing, ground following radar, capsule ejection, etc. the TFX (F-111) had its problems, as had other great aircraft.
Very nice conversion work
