Weight of the components
due to my hard crash on the weekend I decided to take my Eachine Racer 180 completely apart.
I weighted all the parts so maybe this is interesting for someone.
- 1 sideplate 30gr
- complete carbon frame 75gr
- all mechanical parts 67gr (without the yellow box)
- my upgraded servo 48gr
- 1 complete arm 83gr
- all electronics 79gr
So in total mine will be around 435gr without battery.

Eachine Racer 180 IMU board connectors
Hey for all the guys out there, here is the contact plan for the eachine 180 racer flightcontroller…
This is a customized F3 board.
Thanks to Eachine for providing this.

Project unknown further thoughts
I think we have a proof of concept with some risks. When I think about the setup all is done, but will the FC do the things I want from it?
I was dealing with a brand new flight controller from far east. It is a FC with a built in VTX and OSD. Long story short with our brand new design it is not possible to use the onboard OSD. We are still trying to find out what is the most stable (in case of a crash) and most agile frame with less weight. Also we are thinking of a race unit or going for a video stabilized quad with longest flight times. Maybe a mix of both worlds. „Project Unknown“ will be a milestone for the future if there will be no other vendor from far east to force us on our knees.
Trappy this is your chance to get in contact with me again. PJCTUKNWN will be a huge impact if we will get it to life…
dual tilt multirotor
As I dive more into the multirotor builds there are more ideas to construct the perfect copter. right now I am thinking of a quad with 2 tilted axis. So the gimbal is obsolete at this build and the agility is much improved to any other multirotor on the market. The pitch and the roll will be done by special axis not by the props itself. the advantage is more speed and more stability for the camera on board. I will try to get a workring prototype as soon as possible to test out what I am thinking about. There will be a fully stabilized cam on board with the same power and speed as a quad racer, hopefully. The design will be at 8-10″ props but more powerful than everything is on the market at this time.
3rdeye or 3rdeee TE981H firmware misflash
Last weekend I did a mistake and flashed an old firmware on my 3rdeye fpv monitor. So it ended bricked with colored lines on the screen. 3rdeye told me that I have to send it back to them (to china). They provided a correct firmware for me but there is no screen even on the av out to go back into the menu to flash from sd card. Today I decided to take it apart. While dismantling the device I broke the switch for changing between movie and recording which is not a big problem for me if I can bring it back to life. So here are some specs the vendor is hiding so far.
- Battery 3.7v 3200mAh 11.8Wh
- Cpu Zoran ZR36490BGF
- SK hynix HY27US08561A (memory)
- SK hynix H5PS5162GFR (sdram ddr2)
- Techwell TW9910 (video decoder)
- SM201R (120mW video receiver)
Also there are only 5 buttons on the front frame but on the mainboard there are 6 buttons one is on the top which maybe only does a reset of the device. I will try my luck and hopefully find a way to flash it by myself.
