224 has more total timing available than any of the other firmware. If you're running in a class where a lot of timing is needed, you may well find this to be the best firmware.

Almost all of the setups posted for 119/211 are using maximum timing (as do all of my setups). To me this means not enough timing is available; the upper limit should be what my motor can take, not what the firmware allows. The maximum setting should basically turn the entire car into liquid metal and make small children cry.

I think Hobbywing bottled it. They released 224, a couple of idiots cranked it up to max without checking motor temp and blew their motors, so Hobbywing withdrew it and calmed it down for 119 to avoid the complaints.
