Default Phnx 25 overheating?

I am running a Nippy 280 silver with the variable pitch prop( the blue 9.75" one) and a 3 cell 1050 lipoly with 4 servos 2 HS-55 and 2 gws naro/std. I just hooked everything up and wanted to see if it all worked ok and I ran full throttle a couple of times for a few seconds and I noticed the speed control was too hot to touch even melted the shrink wrap covering a bit. I know with the bec enabled I should only run only 3 servos or a smaller battery but others said they get away with it all the time. I disconnected a servo and took the prop off and ran the motor and the controller still got pretty warm or warmer than what I think it should be. The motor specs say that with a 9x4 prop at 8cells the amp draw should be about 9amps. I am going to try a smaller prop but I dont think thats going to help since it still got warm with no prop. Do these speed controlls heat up regardless and need air flow for cooling?

Appreciate the help.
