These speeds should not be sold at all. I bought 2 of 80 amps. One at the ground cut the motor in 10 seconds in full throttle. So I did no used at all. the other one I thought was working on the ground. But when I flew about 1 min the motor cut of and I crashed my airplane. The seller was great refunding me the one that did not worked from the begining but for the second I had this bad surprise. In Youtube there are many people complaing about the same issues with these esc's. And yes I read the manual and tried many different setups with no luck.
hope it will work
