Silverware is an open-source flight controller firmware developed by GitHub user silver13 for the H8 mini, BWhoop B03, Eachine E011, and E011CÂ FCs. It was forked and further refined by GitHub user NotFastEnuf.Â It gives you acro mode, is optimized for the STM32F0 processor and is very well-tuned for brushed motors (especially the NotFastEnuf fork).
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:
- Molex battery male connector
- LiPo battery with Molex battery female connector
- Soldering iron
- Soldering wire
- Wire snips
- Philips screwdriver
The Furibee F36 transmitter with its internal antenna doesn’t have much range. This is fine with line of sight (LOS) flying but with first-person view (FPV) flying, you’d probably want a bit more range. We can drill a hole through the casing and thread the antenna through and out of it which can increase range. But why stop there? Let’s install an external antenna.
The controller “sticks” of my Cheerson CX-10 is rather short. So I fashioned extended sticks from ballon cups I picked up from a kiddie party.
What a huge difference! The longer sticks translate your input to smaller angles so the quad is not as twitchy and abrupt as before.
