I agree that it needs to be balanced inverted. I just completed the kit 3 days ago and I only needed 2 oz in the noze to balance it out and that's with a balsa cowl, wheel pants, flying wires, tail dragger, etc (too many other extras to count). I've got the pics to prove it. The only con I could say is that the quality of the balsa and plywood in my kit was sub-par, but the way it flies far makes up for it. I've got a 46 AX pulling it and man it hauls a@#. Sorry about your experience.

Here's my thread:
