Do some receivers require ext. batteries?
 

I have a T-Hawk small parkflyer (similar to AeroBird) and I am considering a new radio system. I am looking at growing into a radio so I want to consider a 5 or 6 channel system. Some of these radios hint that the receiver needs batteries. I am concerned that the lightweight of the T-Hawk can not afford to take more batteries on-board. Am I interpreting this correctly? - do most receivers require a couple of AA batteries?

Thanks!

RE: Do some receivers require ext. batteries?
 

In the Glow World, all receivers require a battery pack to operate.


In the Electric World, most receivers use the BEC (Battery Elimination Circuitry) in the ESC (Electronic Speed Control) to eliminate the need for an additional battery pack for the receiver. The BEC will automatically cut off the motor when the main flight battery reaches a certain voltage. This will allow you to "glide" the model back for a landing.

I hope this helps.
