the min throttle and min brake is made the car feel so much better with 212... Plus the other difference I noticed from any other firmware til the new 212 came out was the brakes on a brushed motor didnt really work at all and very weak.. But with the 212 it fixed the problem and the brushed has brakes just as strong as what you can setup with brushless.
Trust me nothing besides those three things has changed between 208 and 212.. You can use 212 without the min brake and min throttle anyway by turning them of and ta da you have 208
