Flew my tribute today. This thing is great! Although I realized that a brush-less is the only way to go with this model. I have an AXI in my ultimate and it does a vertical take off. I'm going tomorrow and pick up a brush-less. Thought I'd try an eflite out-runner & a castle 25 amp speed controller. I'm thinking of getting a 800mah 3S battery this time to save little weight.
