I have owned 3 CSM 360's in their time they were really good except for the slight drift I had with them. I just bought a CSM 540, how does this unit stack up against the 360 as far as performance?
I have went to the Futaba line on all of my other helis from the Gy 240 to 401's now. I will be using a JR hi speed digital DS 8417 servo on her heli. (wifes)

I use them exclusively for now. I have 7 of them and have no problems. I don't push them hard like a lot do but they serve me well as you can pick them up reasonable used.

They will sometimes still exhibit a bit of drift due to severe temperature change. If the heli is setting in the sun it will drift a bit when the rotor wash cools them down. Nothing that a couple clicks of trim doesn't fix.

The older Telebee on her heli was good too, but it had the same drift as well. GG, for what I'm giving for one used I can not complain. I thought the older 360's were good too.
