I hate to state the obvious, tmw09, but you might try a Hangar 9 Twist 60 ARF to go with your Evolution .61 NT
If going with the twist go with the 40 size for your Evo .61. The Evo .61 is not enough for the 60 size twist, (it will fly the 60 twist but you will not be happy with it.)

I have the AT6 with a Evo .61 & a Pitts style muffler on it & it works Great.
