Well i flew my Diablo for the first time today. Pretty docile flying plane. Lands slow. Added a half ounce of lead to the front.

As stated in an earlier post the negative lead was a little loose. mine was also a loose fit.
once in a while the esc would glitch.

It is not fast guessing 30mph. I would rate it for the eighty dollars i paid for it thru Towers scratch and dent a pretty darn good deal.
If i had paid two hundred. Not such a good deal. I may try and teach my nine year old nephew how to fly on this plane.
