it'll be ok for sport flying, just not for mis-timed 3D manuevers. i acutally modified it abit. i kept the hh gyro gain at 100%, and about the sweat spot on teh stock gyro, however, i also dailed in some revo mix and now the tail seem to stay very put during my test flight in my living room. constantly punching up and letting go... i'll have to test fly it to see how it'll work outside. i really dunno how all of the 'pros' got their hh and dd tail to hold SOOOOO good without the use of revo mixing. anyways, you can try it to see if you like it, if all your doing is fff and a loop or two, it shouldn't reveil any problems.
