That is strange. I have the manual and read through it last night. I still don't know what the initials HRS or PPM stand for. I didn't see a list of excluded escs. Where does one find that information?
I am going to be a Hitex HFX, just because I find them simple to operate and basically bulletproof.
Lots of cool stuff in the manual. Even the manual is good looking.
