Maybe I'll try this here. Didn't seem to get much responce in the other area. Been reading and learning and am wondering , on my 500 do I need to run a separate Bec or not? I'm putting together a 500 with a Scorpion HK-3026-1900KV with a 13 tooth pinion and a Castle Creations ICE100 Esc. Servos are going to be Hitec HS5245s and a 401 Gyro.

CC. says that the internal BEC is good up to a 500 size Heli.

Looking up the ESC you quoted it appears to include a 5A BEC and factory set to 5V. You can increase the voltage up to 7 volts but I would be careful going too high because your servos are only rated to 6V. Therefore you do not need a BEC. You did not list your tail servo...some tail servos can not handle more than 4.8V...if that is the case you will need an inline step down or diode for your tail servo only. Otherwise if you leave the voltage on the built in BEC at 5.0 volts you should be fine...no separate BEC or separate inline regulator needed.

Thanks. Not sure about the tail servo yet. I am familiar with the step down, I use on on my raptor 50. Thanks again.
