Slope % and degree relation
Have you ever wondering how this works. Degree is clear, but % little bit more complicated. % says what is the height difference in relation to the horizontal distance in other words tangent of the degree. Following graph is self explaining. Note that 100% slope is exactly 45 degree.

Router ASUS RT AC58U as wireless bridge
My router went to silicon heaven and I needed to replace it.
I needed to connect two rooms in order to share network printer, NAS, and other devices. I have chosen router ASUS RT AC58U and bought two of them. By surprise these routers do not support wireless bridge mode.
Wireless bridge scheme
After some searching there is ingenious open source project for routers firmware. LEDE Project This software completely replace the firmware and open all imaginable features. The firmware requires some knowledge of the networking and if you are not familiar with words like bridge, firewall then the beginning could be difficult.

During experimenting is useful to know how to do factory reset.
- The router can also be reset by locating the reset button located on the router. This is located on the back or the bottom of the router.
- Press and hold the reset button on the router until the power light on the router begins to flash, and then release the button.
- The router should reset the settings and restart. The next time the router is accessed, the initial setup screen will appear.

EACHINE ARF X220S setup
Beginner notes on setup of ARF X220S.
1. Install extension Betaflight in Google Chrome. This is very nice program for complete setup of Flight Controller Omnibus F4 SD. SD stands for SD card.
2. Update FW. For booting of flight controller in update mode you need to hold button next USB on flight controller. Green LED will light. Probably you will need to install drivers for Update mode and maybe for normal mode.
Just the top of the frame needs to be disassembled in order to reach the button.

3. Setup of Betaflight
4. Receiver installation. I have bought R820X v2 from Hobbyking with SBUS output. This can be directly connected to flight controller. I have completely stripped off the receiver and soldered the cable to Bind connector of the receiver. Works nice!
