There are 4 deep seated screws in the rear of the bottom hull. You can't miss them, and these come out. Ok now HOW does the hull come off? You removed the treads like i did, and the hull screws are NOT THERE they are clearly located somewhere else then in the tutorial!
I gently pried open the hull and looked inside towards the front. It became clear there were screw holes, behind the spare tracks in their holder, on the lower front of the hull. So those had to come off. You can wiggle them off easily with a screwdriver, without breaking them. And behold, there are your last two screws, in the holes shown here.

I didn't do much else to it today at all except drive it and mod the transmitter to make the battery contact improved.
Added a brace of aluminum strip where i thought it wouldn't affect the turret rotation. Also painted the tracks with rustoleum red primer for that rusty track look, they are going to get touched up with silver at the contact points later, of course.
