Looking good there,nice to see a picture of XV295,my favourite Herc,i was involed with the modification fitting the llltv camera below the front window and the the turret below the radome,a great job to be involved with.Concerning the undercarriage,there is a ball screw attached to the top of the oleo assembly which goes up through the roof into the area below the wing.There is an opening above each oleo to allow the leg to be retacted up through the roof of the bay.There is no beam across between the top of the oleos but all the way up just below the wing at the top of each ball screw is a gearbox that is indeed conneted to its neighboring oleo and the drive motor.I hope this helps.
