This is a great model. I found it challenging to make it as close to the real Zeppelin as possible. I checked, that Marklin have manufactured tis model back in 2010, but their version was with 4 wheels and motor bogies.
I did some remix, made a ram for 2 wheels and installed a 8,5x20 mm drone motor with a 45 mm propeller.
the motor is a 8,5x20 mm drone motor and the propeller is a 2 blade, 45 mm drone propeller.
I use a DC wheels, which are installed in the opposite direction. I copper wire is winded arround each axle to get the electricity from the tracks. I added about 50 g of additional wight, otherwise I had problems with taking curves at high spped.
