Silverware is an open-source flight controller firmware developed by GitHub user silver13 for the H8 mini, BWhoop B03, Eachine E011, and E011C FCs. It was forked and further refined by GitHub user NotFastEnuf. 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
Procedure
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.
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.
The Kingkong Smart100 is a good and popular brushed micro quadcopter. However, the big 8.5x20mm motors have a tendency to burn the MOSFETs if you fail to cut the throttle during crashes.
