Tamiya RC Motorized Support Legs (Part Number: TAM56505)

[CustomRCmodels]

They add a lot of cool play-value to your tractors and trailers .
Typical Tamiya quality in regards to how they are made .
But out of the box they only work good if your tractor and trailer on leveled ground .
All my tractors have modified spring-loaded 5th wheels and extended support legs ,
so I can do the coupling and un-coupling functions on uneven terrain as well ( outdoors )
also to make up for the different tire-sizes I use on my trucks .
