Eachine E011 Transmitter Battery Mod


The Eachine E011 transmitter takes in 3 AAA batteries. But alkaline batteries almost always suck and Eneloops are rather expensive. And they often tend to inexplicably disappear. Besides, I have a lot of LiPo batteries that I use on quadcopters so it makes sense to make use of them in other battery-operated equipment where possible. This mod is simple and easy and should be applicable to most transmitters similar to the Eachine E011’s. Plus you should still be able to use AAA batteries.

Parts and Equipment

For this mod, you need the following:

  1. Molex battery male connector
  2. LiPo battery with Molex battery female connector
  3. Soldering iron
  4. Soldering wire
  5. Wire snips
  6. Philips screwdriver


  1. Unscrew the back cover of the transmitter and thread the battery connector through one of the holes in the battery compartment.
  2. On the other side, solder the connector ends to the corresponding terminals. Red to red, black to black.
  3. Connect the battery and you’re done!

Low Profile Rakonheli 66mm With Beecore Brushless FC

An all-in-one brushless FC and ESC board has finally been released. It took a while for me to get my hands on one and even longer to get to building with one. Now, I use it with my favorite brushless whoop frame. Here’s how to build Rakonheli 66mm brushless whoop with Beecore Brushless AIO FC and ESC.

Building A Better BWhoop B06

The Boldclash BWhoop B06 is a good entry-level brushless whoop. However, it has a few problems for me. First, the motors are not good. There are reported problems of shaft collets and bushings falling off. Second, the FC has no OSD. Third, I prefer my whoops tiny, and by that I mean 65mm (okay, a smaller version is supposedly out but it’s not yet widely available). So I build a better BWhoop B06.
