I know some speed controls are rated up to 200+ degrees so just curious if this is an acceptable range?

However electronics don't run as efficient unless their at operating temperature, so a little warm, or warmed up if you will. If your esc gets to 140 or 160, u should be just fine, but my first esc (brushless) never got hotter than say 120 130, and I've been running it almost daily, for over 5 years. Back then it was 95 bucks, so I've gotten my money's worth out of it. 

It's not that a cold esc isn't efficient, but that they seem to "like" to run when warmed up.

lol ok let me try this another way....

Most low amp ESCs have a limit of 200F, if ur motor or esc are not over heating and u like what u aregetting from it speed and power wise then u are laughing, but this is the fun part, if that happens u can always go up a cell on lipo. If u dont want to go up a cell u can always change the gearing of the pinion or spur... to get more out of what the ESC motor combo offers.

I put a fuze 5800 KV in my mini flux and on 2s at 30 burst, the thing was smoking after like 5 mins, smoking as in really damn hot and the esc wasnt going in to fail safe mode, im not sure why, but there was smoke coming out of the motor wires, was it fun watching it smoke damn rights, was it fun getting the speed i was getting from the mini flux? hell yes, i didnt dare press full power because every chance i got to do that i ran out of room, was it hard on the esc? and motor i sure as hell think so i couldnt touch the motor.. but im sure the esc was under 200F because it never hit protection mode and i was too afrade that the motor was ganna bust and set my flux on fire, so i downgraded and put a 3300 kv in the flux is it as fun was it was before? not really lol but its safe.

The 5800 went in to my tamiya drift car .

For you OP that is an acceptanble range, any how u can always be safe and have a heat gun on hand
