Default RE: Hitec Laser 4

ORIGINAL: under_par_00

What is that used for and do I need it?

If this airplane is a glow powered airplane then yes you are going to need it. Something has to power the Rx and the servos.

If this airplane is an electric then you may not need it. Many electronic speed controls in an electric airplane flight pack (a flight pack is all the electronics that go in the airplane) have a BEC feature. This Battery Eliminator Circuit allows the motor battery to power up the Rx and servos. A few with very high capacity for large cell count batterys may still require a separate Rx battery pack.

Hitec radios can be ordered with flight packs for electrics that include speed controls and approriate sized servos and you may want to search on Servo City as a good supplier.
