why are my temps so high???

Is your source a helicopter or plane person?

While it is true that they operate very well at higher rpms - this is probably more true in models where they will spin to that RPM and gnerally just stay there (like a heli where the head speed stays pretty constant once the model is in flight). They will also pull goobs of Amps to get there starting off.

Take a read through some heli threads - these guys use 10-12S setups and can pull 15C constantly for the length of the run. They will heat up and fry motors faster than us - and their flight time is usually under 10 minutes.

A motor configured to spin up to 50k+ rpms will draw as much power as it possibly can to get there as fast as it possibly can - thus heat. If you do this over and over - acclerate/brake/accelerate/brake/accelerate/etc...... - you will definitely heat things up fast. And - IMO even if you gear down to normal speeds to reduce the load on the motor you could potentially be running the motor too unloaded and then again - in-efficient motor and more heat.

Take a look at what BrianG said as that makes a lot of sense (for normal running - speed runs are another story as Finnster and jhautz said). A nitro motor generally max's out around 30-35k rpm, spec your ride for 35-40k rpm (I've been re-configuring everything I have to be in the 38-40k rpm range) and with stock gearing (for that model) you will be 10-20% faster than the nitro version - gear down and you can go faster.
