Yes I am using the stock oil weight. Been meaning to change it.

Vida lol. It is taking off real quick. I had the center diff locked before and the aon would flip the mlst on its lid! As for the mamba I haven't tried it on tall grass. As you know as kv ratings increases the torque decreases and vice versa. As I had mention in my other thread the mamba 8k is super fast but I was only able to put the throttle to half way and anything beyond that would just make the mlst lose traction.

Capgun I heard lipos will definatley bring the aon even more to life. I'm working on getting the courage to get lipos or perhaps I'll go see if I can borrow one from someone. I'll get some speed runs up after I finish some applications.
