Hitec Laser 4
Im looking at buying the Hitec Laser 4-4 channel radio for an upcoming RC airplane Im going to build. On tower hobbies, it says that it comes with a battery pack for the transmitter (understandable) and also a battery pack for the reciever which I dont understand. Why would you need a battery pack for the reciever? Thats just extra weight in the plane, right?
What is that used for and do I need it?
You can see on this link the batteries included.
