Glider without BEC?

[Timmy]

I have a simple soarer I want to fly and I dont have a BEC and I don't want to use my other ESCs. Could I plug in a 5V battery or less directly into my receiver? Or will that still hurt it?

yes. you can find a cheap LED flashlight from HF, take the 3 battery pack holder out and solder servo leads to it (only need power and ground). 3 AAA batteries will give you the voltage you need, then just plug into empty spot on your Rx. i have done this on DLG's before and it works fine.

good luck,

me

Thanks!

I use one of these:

Just checking, 3 AAA batteries, and plugged into the + and - pins in the receiver right?

 

[mrjdstewart]

yup. each AAA is 1.5v so 3 is equal 4.5+ volts. you need 3V minimum to run the Rx and servos. this give you a little room to work.

good luck,

those will work but 4 batteries is a little over kill for voltage and weight. i really like the cheap LED flashlight that you can get for $1. they have the same thing but with 3 batteries instead of 4.

laters,

I'm using rechargeable batteries. Each has 1.2V. I tested it. It still works fine for 2 servos.

Back in the 72Hz days, we used 4 batteries, either AAA or NiCad.

If you want to save some weight and can solder, there are 3.7v batteries available for cameras and such. They are smaller and lighter than AAA or AAs and you only need two.

I actually need nose weight so weight is not a problem.
