This is probably the most complex RC we have ever filmed for 'Essential RC'. I cannot imagine the engineering that went into making this AVLB. The owner was using a highly complex transmitter with many channels to control the many features of this vehicle that enabled it to deploy the bridge. Quite a feat of engineering as moving the bridge off the vehicle obviously changes its balance/centre of gravity. I could see the special stabilisers were first deployed before moving the bridge. This is a long video. It also shows how the bridge is recovered back onto the vehicle.
This area and the vehicles were exhibited by Verband der Reservisten d. Bw. Landesgruppe Berlin at Modell-Hobby-Speil in Leipzig, Germany.
