Hi,
am looking for more info about specifications of the standard engines used on HL tanks. It would be helpful to know different (if they do are different) engines used on the models. I especially need to know the input voltage.
I read about 'white caps' and 'black caps' but was unable to figure out differents specs for these engines.
Are they speed 400 (6V)? ([link=http://www.hobby-lobby.com/speed400.htm]link[/link])
or 480 (7.2V)? ([link=http://www.hobby-lobby.com/speed480.htm]link[/link])

I would also like to know if different engines are suggested for the 3:1 gearbox.

Many thanks
