I recently purchased one of the "Mustang P51D EP" models from Nitroplanes. This was the worst kit I have ever bought. First of all, their web site states "battery hatch is in front of the canopy" but there is no battery hatch. This requires you to remove the wing each time you change batteries (which is a major pain). Also, some of the parts were made of a cheap plastic that you were required to cutout yourself. The color of the plastic parts did not match the covering color.

I emailed Nitropanes and requested an RMA so that I could return this plane. Although their web site states that all emails are answered within 24 hours, it was over a week before I got a reply. They offered me a $10 discount if I would keep it. Needless to say, I returned it and requested a full refund of $60. After waiting for over a month for the refund to appear on my credit card, I call American Express and filed a dispute. Amazingly, a refund appeared on my account within a few days.

Their email to me stated that I should try one of their larger planes because the quality was much better and I would be happier with the product. Yea, right!
