Now i have the Realacc RX5808 PRO PLUS OSD 5.8G 48CH FPV Receiver with the Achilles Open Source firmware for my Fatshark Dominator HD3 Goggles. A very good diverity module with best firmware, that I see. The Achilles firmware is ease to use and now with OSD on the goggles.
The RX5808 have the Achilles firmware version 1.8. Thedisplay is bigger as the display from the Pro58 and with integrated OSD on the goggles display's.
The new RX5808 PRO PLUS OSD have the same faster STM32 F1 CPU that is working in Eachine Pro58. The old RX5808 PRO PLUS Module have still the slow rate MWC CPU.
My version is without the cover, but I have a 3D printer.

Get the RX5808 PRO PLUS OSD with cover here:

It is known to use the F765 processor and many other upgrade updates. But I don’t know if the current Ardupilot firmware supports it or not. I’m going to use a traditional helicopter to test this flight control. I need to ask whether AC 3.6rc1 FW supports this.

CUAV Pixhack v5 has already performed a preliminary test flight on the Alzrc 420 three-bladed version of my 420-level RC helicopter. It performs very well in all aspects. For example, the calibration process, vibration control, and flight stability of each sensor, the actual flight effect is still Quite well, thanks to the developers of ArduPilot, @tridge、@rmackay9、@ChrisOlson. they have efficiently released the Dev version firmware with great usability.

A few steps in between finish work lowering the side doors of the cowl and re-cutting the air outlets and carburetor filter opening. After reworking the shape and finishing of the glass re-work I lowered the engine side cowl on both sides, by about an inch . Using strip styrene I created a dam to build up with bondo fill, which was sanded flush to the styrene and feather into the sides to give the appearance of a single door over-lapping metal cowl door. I will make some cowl latches to give the appearance that the doors are held closed with these latches. The changes can be seen in the original cowl molding verses the changes made to my cowl.
My next step is to make the carburetor hood and inside filter , air outlet openings and finish , fill prime the cowl .

Foxeer Predator vs. the sunset | FPV CAMERA TEST (4 min 26 sec)

This is a DVR of the FOXEER PREDATOR V1 flying in one of the most difficult conditions: the sunset. There are a lot of shadows, different lights to handle, terrible backlit. I was really astonished by this camera, I've never seen so well in this conditions and I had no problem flying in any direction and in the shade. I can only imagine how good could it be the V2!!!

In the video I use the standard settings of the camera, the video's not been modified with any post production adjustments.

Coming soon a full test comparing:
- predator v1
- predator micro v2
- runcam swift 2 (the cam that I've always used before trying the predator)

N.B. All the images problem are only due to the bad DVR of my fatshark!

You can buy the cam here:

I have two LiPo batteries. One is at 3.7V (new battery) and other is at 3V(used one). I connected them in series and tried charging them in balance mode using iMax B6AC. But I am getting an error shown in picture.
