Thanks for the info. I really dont have any mods to make it "fly easier" or "better" I am willing to try anything. I will probably get a T-REX to build anyways. What are your suggestions for mods? I have read some on the forums but only tried a few. I have the super skids tried the fly bar wieghts and even the flat bottom plastic blades. That was the worst. The plastic blades broke everything. What did you have in mind?
