I couldn't contain my maniacal laughter when I had this idea, and although it looks like a radial engine stuck to a toilet seat it is truly quite wonderful
allow me to digress.

Storytime:
A while back I spotted a large ancient vase in the palace at maywar. I then some how had the idea to pick up a convoy truck and put it in said vase. this however did not go to plan, I originally use a gyro powered helicopter i made (as it had huge lift power) but after picking up trucks with a magnet in many attempts i couldn't control it well enough to drop the truck in the vase. i then use used a land base vehicle (a modified "wheeltrack" from DustyT33) but found that the truck just didn't seem to fit and I eventually gave up.

A few days ago I had the idea to make a truck with a ramp and let the convoy drive up the ramp into the truck, this had mixed results. The convey vehicles would overlap and sit inside each other but I managed multiple times to get many of them in the truck. today I jokingly said I would make one with a rotary magazine, and later in the day it wasn't a joke anymore. so here it is the revolver convoy catcher.

There was also a point where I was catapulting the convoy trucks out...

controls:
roll, rear steer
yaw, front steer,
VTOL, change barrel slot
Ag1: raise/lower ramp

You may need to create a custom location to start on maywar outside the palace thing.

The modified wheeltrack can be found here

May the maniacal laughter be yours!
