Have done some work with the return rollers.
Threaded Iron 4mm, locking nuts, nuts, washers, tape and treadlock.
Had to move 3 of the return roll for the roadwheels to move free, so no road wheels touch up in the rollers.
Got enough space to put the battery in place. Attached the battery with this strips.
Sealed off all the open holes with tamiya putty, so now the lower hull should be "watertight".

Next task is to see if it is possible to change the turret and gun elevation motor to HL. The included HE are noisy!.
Then RX18 and IR in place in the tower.
