Reloadable Lander and Box Rover 3.0

This is the third version of the reusable lander concept I've been working on. The box/rover transformer seems to work as intended so it hasn't changed much. However, I've been having trouble designing a lander that can reliably get the box rover to the surface of another planet without it falling out as I approach the destination. This is the best I've come up with so far (anyone wany to help?) but will continue to work on it when I have time. I have a different design that I will upload tonight but it has the same problem as this design.

This version has a top and bottom platform that allow you to "sandwhich" the rover between them. The platforms are inside of a cargo bay that is opened while the rover is loaded onto the lander. Once loaded and "sandwhiched" inside of the platforms, close the cargo bay doors to increase security even further (you can probably get this to luna, I've only tried a couple of times).

Steps:
1: Activate AG1 and AG3, Slider 1 max
2: [(Switch to rover) +AG4/Slider1 max
3: Slider 2 up briefly to drive into position
4: B to brake, Slider 1 middle to box
5: [ to lander, slider 1 middle and then deactivate AG1 and AG3

LIFTOFF!

Rover controls are the same as last two versions.

If you can land the rover on a planet, please let me know as I'm not sure if it's a design or navigational error.

Pictures show rover being loaded, platform raised, cargo bay doors closing, and then opening doors after liftoff to show the rover inside!
