Hey bryis, glad to read you've completed your first build and it looks great. Sure you'll have a blast when you fly it the first time. Just one quick tip, i see from the pic you have the muffler on your AX orientated so the exit points up and out. I had mine like this till my instructor told me to rotate it 90 degrees so it points down and out. Its easy to do, check the AX manual.

So what you building next??
