much better than a DLE55.i am spinning a 24-8 NX prop at just over 6500 with a DA side dump muffller.if you do a search you will find that the DA is getting 6500-6600 on a Xoar 24-8 with the same muffler.
Xoar laminate 23-8 at just over 7150.i am waiting for a Falcon 24-8 for my next prop to try.
as for now i like the 60, as long as it holds together,time will tell.
