BeastX does have it but I'm not sure what it's for, as it doesn't seem to eliminate the need to provide cyclic to counter the tail push.
The Nano does beautiful slow piros if you do it right - better to the right than to the left, but it does nice piros, the tail control is fairly precise on it. You can do the Finless Bob challenges with the Nano...
(#1 - challenge #2 is slow piros)
