Lehner 1930 for Traxxas Jato?

Doese anyone know where I can get the Lehner 1930 motors from anymore.

Also doese anyone know if the Lehner 1930 motor will run of the Mamba maxx controller?

I want to ger the Jato up to a 54T Spur and a 33T pinion and I am thinking that the Mamba Maxx5700 that I have in it at the moment might get a bit hot if I try to run this high gearing.

I think the Lehner 1930/6 might handle it on 3s lipo 8000mah. Should rev up to 38,000 with this voltage.

Has anyone had anything to do with these Lehner 1930 motors? Will it run too hot with this gearing in the Jato?

Also trying to find some specs on this motor. Mainly the length and diameter.

Any information appreciated
