My experinece if useful for somebody.
I used two years ago, big size no many options and the setup is very fragile, each time I run have to trim several times the Tx to avoid the tank runs or turns by itself. I repeated the setup process many times in the past and once you turn off for several days again have to trim very carefully to get the neutral.
I tested with Futaba 27 and 72 and Turnigy 2,4 and the same. Once trimed run well, the sound is poor.
I didn't check Clark, but Tamiya or HL don't have this behavior, make me remember the old ESCs I used for cars in the 80, when you had to trim permanentely to get neutral.
My 2cts... you know LOL
