For the camera mount i suggest you use long m2 bolt that go all the way through the mount and have a nut at the bottom and cut of the remaining bolt.

Best looking elf build!

[@popovek]

Perfect! Very neat Assembly!

What are your PIDs? I build and am getting crazy oscillations.

This was long ago and I'm not sure if I did anything special there. If I remember right, back in the days of Betaflight 3.2 or whatever the version was the advice for micros was to take Betaflight defaults and halve P and D gains. What I can also suggest trying is flashing Betaflight 4 if your FC supports that and using community presets for 2"-3" quads: github.com/betaflight/betaflight/wiki/Community-Presets#2---3-quad---11xx-12xx-motors

I wanted to build a quad just like this one but without the fpv stuff, just do fly line of sight because I love micros, however the ones that come pre built are almost all toy grade and don't have the power I would like them to have. I'm sure it can be done but correct me if I'm wrong. I want to do it AS CHEAP AS POSSIBLE if anyone can help me out I would be very grateful! 🙏

I am building this frame with DYS BE1104 7000KV and Gemfan 2035 4 blade props. AUW is 105gm with a gensace 800mah 2S 40C lipo. I don't want to fly in speed. Will I have any issues to get the quad off ground?

[@ErgoFPV]

I found static thrust figures for 6500 kv: fishpepper.de/2017/12/03/thrust-test-dys-be1104-6500kv/ According to that, I’d expect power to weight ratio about 4 given the battery can supply about 20 amps, which matches its capabilities. Thrust to weight ratio of 4 is quite low, but it will fly. You might fing throttle resolution a bit low though.

[@hengthanak5552]

This build would be perfect with 1104 7500-10000kv motors. The 1105 is a bit heavy and under prop for 2inch.

Can You give the file for camera mount printing?

[@ErgoFPV]

Hey. The first version of the camera pod and rear standoff is here www.thingiverse.com/thing:2774645/files Afterwards I made it a bit taller (23mm instead of 20) to account for more electronics inside. I will later upload that version's files to Thingiverse as well.

ErgoFPV Thanks!
