"Standard ESCs are actually not designed for multirotor applications. They are programmed to increase and decrease the throttle command towards the motor in a gentle way. The reason for this is quite obvious. Imagine a motor accelerating and decelerating so abruptly in a helicopter or car... it would damage the gears and reductions in no time. In a multirotor application, we really want just the opposite. The goal is to change the motor speed, and thus the thrust, as fast as possible to achieve a perfectly stable platform.
While the current ESCs used in most multrotor applications work considerably well, there is a lot of room for improvement. Using the same ESC, but loading it with dedicated optimized software, will increase the handling and stability of your multirotor greatly.
We call this RapidESC: converting your regular lazy ESC into a high speed capable speed controller at no extra cost, ready for multirotor applications."*
These are one of the best types of ESCs for the SimonK firmware. Read first post here
"The ESCs which use only N-channel FETs have the advantage of lower resistance, less losses and hence more efficiency."*
"An external oscillator may supply a more consistent timing signal and steadier motor speeds" "but the internal rc oscillator ones will drift quite a bit based on temperature."*
HobbyKing F-20A Tested and flashed with latest SimonK with bootloader enabled so you can flash them in the future thought the servo cable with the USB linker from HobbyKing. I cut a little flap out and use clear tape to cover the opening. You can barely tell.
Selling them for $15 each ESC plus shipping US shipping only.
If you're interested send me a PM so I get proper shipping with your address. I'll be doing USPS shipping. It's $6.
Any question feel free to ask.
What is RapidEsc (Simonk firmware)
All N-Fet Design
