Here's a video from the last time I played before I took it apart because of the servo.
I have the cooling fan running directly off of the battery now. I did something bad to the receiver and reception is good till around five feet. You can sometimes see the black on the pistons. That's oil and dirt, it isn't a major leak or anything, but I still want to try different O rings and see if I can't eliminate most of it.
