I'm fairly new to electric RC and would like to know if the following setup will run OK:

Castle Creations Phoenix 25A brushless ESC
2 Hitec HS 55 servos
2 Hitec HS 81 servos
3 cell Li poly

I've read some other posts and there seems that there can be an issue with overheating the BEC with the high voltage from a 3 cell while running 4 servos. My assumption for now is that the current draw from the small Hitec servos listed above should be low enough that it will not overheat the BEC. Also, I intend to give the ESC good cooling air to try to avoid overheating.

Has anybody run the above setup without problems or will I have to go to a 35A ESC?

I have run 4 servos with thaat speed control and never had a problem with it. I was useing a Himax 2812-1080, 4 allerc Micro 9 servos, a TP1320 3-cell, and an 10x4.7 APC prop.

Have 4 HT 55's on a rcx planes Illusion and AXI 2212, TP 1320 battery., 25 AMP phoenix. Everyting is cool to the toutch after 15-16 minute flights. of 3-D. Buy a Watt Meater right away befor you start burning thing up and quit guessing on the draw. My thought is your esc is much to small. You may reduce the size and pitch of the prop until you get the 35. Generally one hot run on your battery and its probably shot? Its much cheaper to know whatts going on"

its against the rules... but it works...

I've run 4 servos on my 25 and my 10 many times....

Ail, Ele, Rudder, Variable pitch... and that stuff is hard on a system...
