In my opinion the plane is not safe to fly anywhere near spectators because of the defective design of the horizontal Stabilizer. Ace representatives explained that you cannot make any modification to the plane or the warranty will be voided. Using a Saito 150 engine or the opening of the covering on the wings or tail would result in a voided warranty... So, this means that virtually anything you do to correct their design flaws will result in a voided warranty. This plane is described as an "Unlimited Pylon Racer" and they say that it is an ARF (almost ready to fly???)... Not even close!
They have won the argument. It is too bad they feel this way... too bad for me too. I will not consider ever buying another product from Ace or Thunder Tiger because of their "perfect legally worded policy".
