Does any one know how to connect the battery to the reciever without an ESC? Does a regulator have to be used? I've never set up an unpowered glider, but need to now. Thanks, The Doctor

If you have a standard voltage range setup, you will either need to find a NiCd flight pack, or use a much lighter LiFe or LiPo battery, with a BEC (battery eliminator circuit) to lower the voltage to 5V. Fully charged, LiFe batteries are 3.6V per cell, so a 2 cell (2S) battery would be 7.2V; a LiPo battery is 4.2V per cell, so 8.4V for a 2S battery. If you have HV equipment, choose the battery that is below the limits, and just plug it in.
At the same capacity in mAh, the LiFe and LiPo are much smaller and lighter than NiCd, which is good in a glider. For reference, my transmitter came with a NiCd pack, at 500mAh, and the LiFe I replaced it with, same size, same weight, is 1500mAh. Some try to use NiMH batteries, as they have the same voltage range as NiCd, and somewhat more capacity, but many cannot provide the current surges that servos can draw, and cause brown-outs, or voltage drops that shut the receiver off momentarily. The same is true of some LiFe batteries, so if that is your choice, make sure you get one that is made for receiver use.
Do some reading, and good luck!
